In his own words on 2 Thessalonians

• 2 Thessalonians 1:2

  For while I say that similar things are written of the Son as of the Spirit, I am rather proceeding to the following point. My claim is not that because something is written of the Son, therefore it would appear to be reverently written of the Holy Spirit. Rather, I am contending against the argument that because the same is written of the Spirit, therefore the Son's honor is lessened because of the Spirit. For they say, Is it not written of God the Father? But let them learn that it is also said of God the Father, "In the Lord I will praise the word," and elsewhere, "In God we will do mighty deeds," "My remembrance shall be ever in Thee," and "In Thy name will we rejoice," and again in another place, "That his deeds may be manifested, that they are wrought in God," and by Paul, "In God, who created all things," and again, "Paul and Silvanus and Timothy to the church of the Thessalonians in God the Father and the Lord Jesus Christ."

  On the Holy Spirit 2.8.75-76

• 2 Thessalonians 2:8

  We have heard that the Lord Jesus not only judges but also punishes in the Spirit. For neither would he punish Antichrist, whom, as we read, "the Lord Jesus shall slay with the Spirit of his mouth," unless he had already judged him as fit for punishment … but the unity of the divine action remains undivided, since Christ cannot be separated from the Spirit, nor the Spirit act apart from Christ. For the unity of the divine nature cannot be divided.

  On the Holy Spirit 3.7.44

• 2 Thessalonians 2:12

  Who, then, is the Lord Who makes us to increase and abound before God and our Father at the coming of the Lord Jesus? He has named the Father and has named the Son; Whom, then, has he joined with the Father and the Son except the Spirit? Who is the Lord Who establishes our hearts in holiness. For holiness is a grace of the Spirit, as, too, is said farther on: "In holiness of the Spirit and belief of the truth."

  On the Holy Spirit, Book 3, Chapter 14, 95

• 2 Thessalonians 2:13

  And the apostle also teaches that the Holy Spirit sanctifies. For he speaks thus, "We are bound to give thanks to God always for you, brothers dearly beloved of the Lord; because God chose you as first fruits for salvation, in sanctification of the Spirit, and belief of the truth." So, then, the Father sanctifies, the Son also sanctifies, and the Holy Spirit sanctifies; but the sanctification is one, and the grace of the sacrament is one.

  On the Holy Spirit 3.4.27-28

• 2 Thessalonians 2:14

  The very tradition, teaching, and faith of the Catholic Church from the beginning was preached by the Apostles and preserved by the Fathers.

• 2 Thessalonians 2:15

  Again, that thou mayest know that the Father is, and the Son is, and that the work of the Father and of the Son is one, follow the saying of the Apostle: "Now may God Himself, and our Father, and our Lord Jesus Christ direct our way unto you." Both Father and Son are named, but there is unity of direction, because unity of power.

  Exposition of the Christian Faith, Book 2

• 2 Thessalonians 3:1

  Indeed, there is good wisdom, but sweet mercy. Few attain the former, while the latter reaches everyone. Because of this, he says, souls renewed by the spirit love you. Hence, it is also said to the soul: Your youth will be renewed like the eagle's. For he was speaking to the soul, saying: Bless the Lord, O my soul. And therefore it hurries to the Word, and asks to be drawn, lest it be left behind; for the Word of God runs and is not hindered.
