2 Tessalonicenses 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 Tessalonicenses 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 Tessalonicenses 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 Tessalonicenses 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 Tessalonicenses 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
