John Cassian

In his own words on Mark

• Mark 6:5

  In some cases he so richly poured forth the mighty work of healing that the Evangelist was led to exclaim: "He healed all their sick." But among others the unfathomable depth of Christ's goodness was so thwarted that it was said: "And Jesus could do there no mighty works because of their unbelief." So the bounty of God is actually curtailed temporarily according to the receptivity of our faith. So it is said to one: "According to your faith may it be to you," and to another: "Go your way, and as you have believed so let it be to you," and to another "Let it be to you according as you will," and again to another: "Your faith has made you whole."

  THIRD CONFERENCE OF ABBOT CHAERMEON 15

• Mark 6:5

  If the faith of those who bring them or of the sick is lacking, it may prevent those who possess the gift of healing from exercising it.

  SECOND CONFERENCE OF ABBOT NESTEROS 15.1

• Mark 9:24

  Seeing that his faith was being driven by the waves of unbelief on the rocks which would cause a fearful shipwreck, he asks of the Lord an aid to his faith, saying "Lord, help me in my unbelief." So thoroughly did the apostles and those who live in the gospel realize that everything which is good is brought to completion by the aid of the Lord, and not imagine that they could preserve their faith unharmed by their own strength or free will, that they prayed that it might be helped and granted to them by the Lord.

  CONFERENCE OF ABBOT PAPHNUTIUS 16

• Mark 10:30

  For he who for the sake of Christ's name distances himself from his particular beloved father or mother or child, and gives himself over to the purest love of all who serve Christ, will receive a hundred times the measure of brothers and kinsfolk. Instead of but one he will begin to have so many fathers and brothers bound to him by a still more fervent and admirable affection. That this is so you can prove by your own experience, since you have each left but one father and mother and home, and as you have done so you have gained without any effort or care countless fathers and mothers and brothers, as well as houses and lands and most faithful servants, in any part of the world to which you go, who receive you as their own family, and welcome, and respect, and take care of you with the utmost attention.

  CONFERENCES 3.24.26

• Mark 11:23

  While we are praying, there should be no hesitation that would intervene or break down the confidence of our petition by any shadow of despair. We know that by pouring forth our prayer we are obtaining already what we are asking for. We have no doubt that our prayers have effectually reached God. For to that degree that one believes that he is regarded by God, and that God can grant it, just so far will one be heard and obtain an answer.
