Background on Irenaeus

In his own words on Mark

  • Mark 1:1

    Wherefore Mark also says: "The beginning of the Gospel of Jesus Christ, the Son of God; as it is written in the prophets." Knowing one and the same Son of God, Jesus Christ, who was announced by the prophets, who from the fruit of David's body was Emmanuel, "the messenger of great counsel of the Father;" through whom God caused the day-spring and the Just One to arise to the house of David, and raised up for him an horn of salvation, "and established a testimony in Jacob;" as David says when discoursing on the causes of His birth: "And He appointed a law in Israel, that another generation might know [Him,] the children which should be born from these, and they arising shall themselves declare to their children, so that they might set their hope in God, and seek after His commandments." And again, the angel said, when bringing good tidings to Mary: "He shall be great, and shall be called the Son of the Highest; and the Lord shall give unto Him the throne of His father David;" acknowledging that He who is the Son of the Highest, the same is Himself also the Son of David. And David, knowing by the Spirit the dispensation of the advent of this Person, by which He is supreme over all the living and dead, confessed Him as Lord, sitting on the right hand of the Most High Father.

  • Mark 1:2

    Wherefore also Mark, the interpreter and follower of Peter, does thus commence his Gospel narrative: "The beginning of the Gospel of Jesus Christ, the Son of God; as it is written in the prophets, Behold, I send My messenger before Thy face, which shall prepare Thy way. The voice of one crying in the wilderness, Prepare ye the way of the Lord, make the paths straight before our God." Plainly does the commencement of the Gospel quote the words of the holy prophets, and point out Him at once, whom they confessed as God and Lord; Him, the Father of our Lord Jesus Christ, who had also made promise to Him, that He would send His messenger before His face, who was John, crying in the wilderness, in "the spirit and power of Elias," "Prepare ye the way of the Lord, make straight paths before our God." For the prophets did not announce one and another God, but one and the same; under various aspects, however, and many titles. For varied and rich in attribute is the Father...

    Against Heresies Book III

  • Mark 1:24

    And through the Word Himself who had been made visible and palpable, was the Father shown forth, although all did not equally believe in Him; but all saw the Father in the Son: for the Father is the invisible of the Son, but the Son the visible of the Father. And for this reason all spake with Christ when He was present [upon earth], and they named Him God. Yea, even the demons exclaimed, on beholding the Son: "We know Thee who Thou art, the Holy One of God." And the devil looking at Him, and tempting Him, said: "If Thou art the Son of God;"-all thus indeed seeing and speaking of the Son and the Father, but all not believing [in them]. For it was fitting that the truth should receive testimony from all, and should become [a means of] judgment for the salvation indeed of those who believe, but for the condemnation of those who believe not; that all should be fairly judged, and that the faith in the Father and Son should be approved by all, that is, that it should be established by all [as the one means of salvation], receiving testimony from all, both from those belonging to it, since they are its friends, and by those having no connection with it, though they are its enemies. For that evidence is true, and cannot be gainsaid, which elicits even from its adversaries striking testimonies in its behalf; they being convinced with respect to the matter in hand by their own plain contemplation of it, and bearing testimony to it, as well as declaring it.

    Against Heresies Book IV

  • Mark 2:7

    Now the commandment was given to man by the Word. For Adam, it is said, "heard the voice of the Lord God." Rightly then does His Word say to man, "Thy sins are forgiven thee;" He, the same against whom we had sinned in the beginning, grants forgiveness of sins in the end. But if indeed we had disobeyed the command of any other, while it was a different being who said, "Thy sins are forgiven thee;" such an one is neither good, nor true, nor just. For how can he be good, who does not give from what belongs to himself? Or how can he be just, who snatches away the goods of another? And in what way can sins be truly remitted, unless that He against whom we have sinned has Himself granted remission "through the bowels of mercy of our God," in which "He has visited us" through His Son? And therefore, when He had healed the man sick of the palsy, [the evangelist] says "The people upon seeing it glorified God, who gave such power unto men." What God, then, did the bystanders glorify? Was it indeed that unknown Father invented by the heretics? And how could they glorify him who was altogether unknown to them? It is evident, therefore, that the Israelites glorified Him who has been proclaimed as God by the law and the prophets, who is also the Father of our Lord; and therefore He taught men, by the evidence of their senses through those signs which He accomplished, to give glory to God. If, however, He Himself had come from another Father, and men glorified a different Father when they beheld His miracles, He [in that case] rendered them ungrateful to that Father who had sent the gift of healing. But as the only-begotten Son had come for man's salvation from Him who is God, He did both stir up the incredulous by the miracles which He was in the habit of working, to give glory to the Father; and to the Pharisees, who did not admit the advent of His Son, and who consequently did not believe in the remission [of sins] which was conferred by Him, He said, "That ye may know that the Son of man hath power to forgive sins." And when He had said this, He commanded the paralytic man to take up the pallet upon which he was lying, and go into his house. By this work of His He confounded the unbelievers, and showed that He is Himself the voice of God, by which man received commandments, which he broke, and became a sinner; for the paralysis followed as a consequence of sins. Therefore, by remitting sins, He did indeed heal man, while He also manifested Himself who He was. For if no one can forgive sins but God alone, while the Lord remitted them and healed men, it is plain that He was Himself the Word of God made the Son of man, receiving from the Father the power of remission of sins; since He was man, and since He was God, in order that since as man He suffered for us, so as God He might have compassion on us, and forgive us our debts, in which we were made debtors to God our Creator. And therefore David said beforehand, "Blessed are they whose iniquities are forgiven, and whose sins are covered. Blessed is the man to whom the Lord has not imputed sin;" pointing out thus that remission of sins which follows upon His advent, by which "He has destroyed the handwriting" of our debt, and "fastened it to the cross;" so that as by means of a tree we were made debtors to God, [so also] by means of a tree we may obtain the remission of our debt.

    AGAINST HERESIES 5.17.1-3

  • Mark 2:17

    For no persons of any kind would act properly, if they should advise blind men, just about to fall over a precipice, to continue their most dangerous path, as if it were the right one, and as if they might go on in safety. Or what medical man, anxious to heal a sick person, would prescribe in accordance with the patient's whims, and not according to the requisite medicine? But that the Lord came as the physician of the sick, He does Himself declare saying, "They that are whole need not a physician, but they that are sick; I came not to call the righteous, but sinners to repentance." How then shall the sick be strengthened, or how shall sinners come to repentance? Is it by persevering in the very same courses? or, on the contrary, is it by undergoing a great change and reversal of their former mode of living, by which they have brought upon themselves no slight amount of sickness, and many sins? But ignorance, the mother of all these, is driven out by knowledge. Wherefore the Lord used to impart knowledge to His disciples, by which also it was His practice to heal those who were suffering, and to keep back sinners from sin. He therefore did not address them in accordance with their pristine notions, nor did He reply to them in harmony with the opinion of His questioners, but according to the doctrine leading to salvation, without hypocrisy or respect of person.

    Against Heresies Book III

  • Mark 3:27

    For as in the beginning he enticed man to transgress his Maker's law, and thereby got him into his power; yet his power consists in transgression and apostasy, and with these he bound man [to himself]; so again, on the other hand, it was necessary that through man himself he should, when conquered, be bound with the same chains with which he had bound man, in order that man, being set free, might return to his Lord, leaving to him (Satan) those bonds by which he himself had been fettered, that is, sin. For when Satan is bound, man is set free; since "none can enter a strong man's house and spoil his goods, unless he first bind the strong man himself." The Lord therefore exposes him as speaking contrary to the word of that God who made all things, and subdues him by means of the commandment. Now the law is the commandment of God. The Man proves him to be a fugitive from and a transgressor of the law, an apostate also from God. After [the Man had done this], the Word bound him securely as a fugitive from Himself, and made spoil of his goods,-namely, those men whom he held in bondage, and whom he unjustly used for his own purposes. And justly indeed is he led captive, who had led men unjustly into bondage; while man, who had been led captive in times past, was rescued from the grasp of his possessor, according to the tender mercy of God the Father, who had compassion on His own handiwork, and gave to it salvation, restoring it by means of the Word-that is, by Christ-in order that men might learn by actual proof that he receives incorruptibility not of himself, but by the free gift of God.

    AGAINST HERESIES 5.21.3

  • Mark 4:15

    For as the good olive, if neglected for a certain time, if left to grow wild and to run to wood, does itself become a wild olive; or again, if the wild olive be carefully tended and grafted, it naturally reverts to its former fruit-bearing condition: so men also, when they become careless, and bring forth for fruit the lusts of the flesh like woody produce, are rendered, by their own fault, unfruitful in righteousness. For when men sleep, the enemy sows the material of tares; and for this cause did the Lord command His disciples to be on the watch. And again, those persons who are not bringing forth the fruits of righteousness, and are, as it were, covered over and lost among brambles, if they use diligence, and receive the word of God as a graft, arrive at the pristine nature of man-that which was created after the image and likeness of God.

    AGAINST HERESIES 5.10.1

  • Mark 4:28

    Those, again, who maintain that the things around us originated from apostasy, ignorance, and passion, do, while offering unto Him the fruits of ignorance, passion, and apostasy, sin against their Father, rather subjecting Him to insult than giving Him thanks. But how can they be consistent with themselves, [when they say] that the bread over which thanks have been given is the body of their Lord, and the cup His blood, if they do not call Himself the Son of the Creator of the world, that is, His Word, through whom the wood fructifies, and the fountains gush forth, and the earth gives "first the blade, then the ear, then the full corn in the ear." Then, again, how can they say that the flesh, which is nourished with the body of the Lord and with His blood, goes to corruption, and does not partake of life? Let them, therefore, either alter their opinion, or cease from offering the things just mentioned. But our opinion is in accordance with the Eucharist, and the Eucharist in turn establishes our opinion. For we offer to Him His own, announcing consistently the fellowship and union of the flesh and Spirit. For as the bread, which is produced from the earth, when it receives the invocation of God, is no longer common bread, but the Eucharist, consisting of two realities, earthly and heavenly; so also our bodies, when they receive the Eucharist, are no longer corruptible, having the hope of the resurrection to eternity.

    AGAINST HERESIES 4.18.4-5

  • Mark 5:22

    Let our opponents-that is, they who speak against their own salvation-inform us [as to this point]: The deceased daughter of the high priest; the widow's dead son, who was being carded out [to burial] near the gate [of the city]; and Lazarus, who had lain four days in the tomb, -in what bodies did they rise again? In those same, no doubt, in which they had also died. For if it were not in the very same, then certainly those same individuals who had died did not rise again. For [the Scripture] says, "The Lord took the hand of the dead man, and said to him, Young man, I say unto thee, Arise. And the dead man sat up, and He commanded that something should be given him to eat; and He delivered him to his mother." Again, He called Lazarus "with a loud voice, saying, Lazarus, come forth; and he that was dead came forth bound with bandages, feet and hands." This was symbolical of that man who had been bound in sins. And therefore the Lord said, "Loose him, and let him depart." As, therefore, those who were healed were made whole in those members which had in times past been afflicted; and the dead rose in the identical bodies, their limbs and bodies receiving health, and that life which was granted by the Lord, who prefigures eternal things by temporal, and shows that it is He who is Himself able to extend both healing and life to His handiwork, that His words concerning its [future] resurrection may also be believed; so also at the end, when the Lord utters His voice "by the last trumpet," the dead shall be raised, as He Himself declares: "The hour shall come, in which all the dead which are in the tombs shall hear the voice of the Son of man, and shall come forth; those that have done good to the resurrection of life, and those that have done evil to the resurrection of judgment."

    AGAINST HERESIES 5.13.1

  • Mark 5:31

    They further maintain that the passion which took place in the case of the twelfth Aeon is pointed at by the apostasy of Judas, who was the twelfth apostle, and also by the fact that Christ suffered in the twelfth month. For their opinion is, that He continued to preach for one year only after His baptism. The same thing is also most clearly indicated by the case of the woman who suffered from an issue of blood. For after she had been thus afflicted during twelve years, she was healed by the advent of the Saviour, when she had touched the border of His garment; and on this account the Saviour said, "Who touched me?" -teaching his disciples the mystery which had occurred among the Aeons, and the healing of that Aeon who had been involved in suffering. For she who had been afflicted twelve years represented that power whose essence, as they narrate, was stretching itself forth, and flowing into immensity; and unless she had touched the garment of the Son, that is, Aletheia of the first Tetrad, who is denoted by the hem spoken of, she would have been dissolved into the general essence [of which she participated]. She stopped short, however, and ceased any longer to suffer. For the power that went forth from the Son (and this power they term Horos) healed her, and separated the passion from her.

    Against Heresies Book I

  • Mark 7:8

    For the tradition of the elders themselves, which they pretended to observe from the law, was contrary to the law given by Moses. Wherefore also Esaias declares: "Thy dealers mix the wine with water," showing that the elders were in the habit of mingling a watered tradition with the simple command of God; that is, they set up a spurious law, and one contrary to the [true] law; as also the Lord made plain, when He said to them, "Why do ye transgress the commandment of God, for the sake of your tradition?" For not only by actual transgression did they set the law of God at nought, mingling the wine with water; but they also set up their own law in opposition to it, which is termed, even to the present day, the pharisaical. In this [law] they suppress certain things, add others, and interpret others, again, as they think proper, which their teachers use, each one in particular; and desiring to uphold these traditions, they were unwilling to be subject to the law of God, which prepares them for the coming of Christ. But they did even blame the Lord for healing on the Sabbath-days, which, as I have already observed, the law did not prohibit. For they did themselves, in one sense, perform acts of healing upon the Sabbath-day, when they circumcised a man [on that day]; but they did not blame themselves for transgressing the command of God through tradition and the aforesaid pharisaical law, and for not keeping the commandment of the law, which is the love of God.

    Against Heresies Book 4

  • Mark 8:31

    Therefore did the Lord also say to His disciples after the resurrection, "O thoughtless ones, and slow of heart to believe all that the prophets have spoken! Ought not Christ to have suffered these things, and to enter into His glory?" And again does He say to them: "These are the words which I spoke unto you while I was yet with you, that all things must be fulfilled which were written in the law of Moses, and in the prophets, and in the Psalms, concerning Me. Then opened He their understanding, that they should understand the Scriptures, and said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise again from the dead, and that repentance for the remission of sins be preached in His name among all nations." Now this is He who was born of Mary; for He says: "The Son of man must suffer many things, and be rejected, and crucified, and on the third day rise again." The Gospel, therefore, knew no other son of man but Him who was of Mary, who also suffered; and no Christ who flew away from Jesus before the passion; but Him who was born it knew as Jesus Christ the Son of God, and that this same suffered and rose again, as John, the disciple of the Lord, verities, saying: "But these are written, that ye might believe that Jesus is the Christ, the Son of God, and that believing ye might have eternal life in His name," -foreseeing these blasphemous systems which divide the Lord, as far as lies in their power, saying that He was formed of two different substances. For this reason also he has thus testified to us in his Epistle: "Little children, it is the last time; and as ye have heard that Antichrist doth come, now have many antichrists appeared; whereby we know that it is the last time. They went out from us, but they were not of us; for if they had been of us, they would have continued with us: but [they departed], that they might be made manifest that they are not of us. Know ye therefore, that every lie is from without, and is not of the truth. Who is a liar, but he that denieth that Jesus is the Christ? This is Antichrist."

    Against Heresies Book III

  • Mark 9:2

    He asserts that the fruit of this arrangement and analogy has been manifested in the likeness of an image, namely, Him who, after six days, ascended into the mountain along with three others, and then became one of six (the sixth), in which character He descended and was contained in the Hebdomad, since He was the illustrious Ogdoad, and contained in Himself the entire number of the elements, which the descent of the dove (who is Alpha and Omega) made clearly manifest, when He came to be baptized; for the number of the dove is eight hundred and one. And for this reason did Moses declare that man was formed on the sixth day; and then, again, according to arrangement, it was on the sixth day, which is the preparation, that the last man appeared, for the regeneration of the first, Of this arrangement, both the beginning and the end were formed at that sixth hour, at which He was nailed to the tree. For that perfect being Nous, knowing that the number six had the power both of formation and regeneration, declared to the children of light, that regeneration which has been wrought out by Him who appeared as the Episemon in regard to that number. Whence also he declares it is that the double letters contain the Episemon number; for this Episemon, when joined to the twenty-four elements, completed the name of thirty letters.

    Against Heresies Book I

  • Mark 9:23

    And not merely in works, but also in faith, has God preserved the will of man free and under his own control, saying, "According to thy faith be it unto thee;" thus showing that there is a faith specially belonging to man, since he has an opinion specially his own. And again, "All things are possible to him that believeth;" and, "Go thy way; and as thou hast believed, so be it done unto thee." Now all such expressions demonstrate that man is in his own power with respect to faith. And for this reason, "he that believeth in Him has eternal life while he who believeth not the Son hath not eternal life, but the wrath of God shall remain upon him." In the same manner therefore the Lord, both showing His own goodness, and indicating that man is in his own free will and his own power, said to Jerusalem, "How often have I wished to gather thy children together, as a hen [gathereth] her chickens under her wings, and ye would not! Wherefore your house shall be left unto you desolate."

    Irenaeus Against Heresies Book 4

  • Mark 9:44

    Since, therefore, He whom these men boast of as their Master, and of whom they affirm that He had a soul greatly better and more highly toned than others, did indeed, with much earnestness, command certain things to be done as being good and excellent, and certain things to be abstained from not only in their actual perpetration, but even in the thoughts which lead to their performance, as being wicked, pernicious, and abominable,-how then can they escape being put to confusion, when they affirm that such a Master was more highly toned [in spirit] and better than others, and yet manifestly give instruction of a kind utterly opposed to His teaching? And, again, if there were really no such thing as good and evil, but certain things were deemed righteous, and certain others unrighteous, in human opinion only, He never would have expressed Himself thus in His teaching: "The righteous shall shine forth as the sun in the kingdom of their Father;" but He shall send the unrighteous, and those who do not the works of righteousness, "into everlasting fire, where their worm shall not die, and the fire shall not be quenched."

    Against Heresies (Book II, Chapter 32), Section 1

  • Mark 10:17

    Some passages, also, which occur in the Gospels, receive from them a colouring of the same kind, such as the answer which He gave His mother when He was twelve years of age: "Wist ye not that I must be about My Father's business?" Thus, they say, He announced to them the Father of whom they were ignorant. On this account, also, He sent forth the disciples to the twelve tribes, that they might proclaim to them the unknown God. And to the person who said to Him, "Good Master," He confessed that God who is truly good, saying, "Why callest thou Me good: there is One who is good, the Father in the heavens;" and they assert that in this passage the Aeons receive the name of heavens.

    Against Heresies Book I

  • Mark 10:38

    They maintain that those who have attained to perfect knowledge must of necessity be regenerated into that power which is above all. For it is otherwise impossible to find admittance within the Pleroma, since this [regeneration] it is which leads them down into the depths of Bythus. For the baptism instituted by the visible Jesus was for the remission of sins, but the redemption brought in by that Christ who descended upon Him, was for perfection; and they allege that the former is animal, but the latter spiritual. And the baptism of John was proclaimed with a view to repentance, but the redemption by Jesus was brought in for the sake of perfection. And to this He refers when He says, "And I have another baptism to be baptized with, and I hasten eagerly towards it." Moreover, they affirm that the Lord added this redemption to the sons of Zebedee, when their mother asked that they might sit, the one on His right hand, and the other on His left, in His kingdom, saying, "Can ye be baptized with the baptism which I shall be baptized with?" Paul, too, they declare, has often set forth, in express terms, the redemption which is in Christ Jesus; and this was the same which is handed down by them in so varied and discordant forms.

    Against Heresies Book I

  • Mark 13:32

    The gnostics presumptuously assume acquaintance with the unspeakable mysteries of God. Remember that even the Lord, the very Son of God, allowed that the Father alone knows the very day and hour of judgment.… If then the Son was not ashamed to ascribe the knowledge of that day to the Father only, but declared what was true regarding the matter, neither let us be ashamed to reserve for God those enigmatic questions which come our way.

    AGAINST HERESIES 2.28.6

  • Mark 13:33

    As, therefore, when the wild olive has been engrafted, if it remain in its former condition, viz., a wild olive, it is "cut off, and cast into the fire;" but if it takes kindly to the graft, and is changed into the good olive-tree, it becomes a fruit-bearing olive, planted, as it were, in a king's paradise: so likewise men, if they do truly progress by faith towards better things, and receive the Spirit of God, and bring forth the fruit thereof, shall be spiritual, as being planted in the paradise of God. For when men sleep, the enemy sows the material of tares; and for this cause did the Lord command His disciples to be on the watch.

    Irenaeus Against Heresies Book 5

  • Mark 14:21

    But Judas having been once for all cast away, never returns into the number of the disciples; otherwise a different person would not have been chosen to fill his place. Besides, the Lord also declared regarding him, "Woe to the man by whom the Son of man shall be betrayed;" and, "It were better for him if he had never been born;" and he was called the "son of perdition" by Him.

    Irenaeus Against Heresies Book 2

  • Mark 14:22

    Giving directions to his disciples to offer to God the first fruits of his creatures—not as if he stood in need of them, but that they might be themselves neither unfruitful nor ungrateful—he took that created thing, bread, and gave thanks, and said, "This is my body." And the cup likewise, which is part of the creation to which we belong, he confessed to be his blood, and taught the new offering of the new covenant. This is what the church has received from the apostles and throughout the whole world offers to God, who affords us nourishment as the first fruits of his gifts in the New Testament.

    AGAINST HERESIES 4.17.5

  • Mark 16:17

    But the Lord, having suffered, and bestowing the knowledge of the Father, conferred on us salvation. For the Lord, through means of suffering, "ascending into the lofty place, led captivity captive, gave gifts to men," and conferred on those that believe in Him the power "to tread upon serpents and scorpions, and on all the power of the enemy," that is, of the leader of apostasy. Our Lord also by His passion destroyed death, and dispersed error, and put an end to corruption, and destroyed ignorance, while He manifested life and revealed truth, and bestowed the gift of incorruption.

    Irenaeus Against Heresies Book 2

  • Mark 16:19

    Also, towards the conclusion of his Gospel, Mark says: "So then, after the Lord Jesus had spoken to them, He was received up into heaven, and sitteth on the right hand of God;" confirming what had been spoken by the prophet: "The Lord said to my Lord, Sit Thou on My right hand, until I make Thy foes Thy footstool." Thus God and the Father are truly one and the same; He who was announced by the prophets, and handed down by the true Gospel; whom we Christians worship and love with the whole heart, as the Maker of heaven and earth, and of all things therein.
