Tito 3:5
Who is the one who is born of the Spirit and is made Spirit? It is one who is renewed in the Spirit of his mind. It is one who is regenerated by water and the Holy Spirit. We receive the hope of eternal life through the laver of regeneration and renewing of the Holy Spirit. And elsewhere the apostle Peter says: "You shall be baptized with the Holy Spirit." For who is he that is baptized with the Holy Spirit but he who is born again through water and the Holy Spirit? Therefore the Lord said of the Holy Spirit, "Truly, truly, I say to you, except a man be born again by water and the Spirit, he cannot enter into the kingdom of God." And therefore he declared that we are born of him into the kingdom of God by being born again by water and the Spirit. — On the Holy Spirit 3.10.64
Tito 3:9
Blessed is that servant [Paul] who can say: "I have fed you with milk and not with meat; for until now you were not able to bear it." … Yet he—being so great a man and chosen by Christ for the care of his flock in order to strengthen the weak and to heal the sick—rejects immediately after a single admonition a heretic from the fold entrusted to him. This he does for fear that the taint of one erring sheep might infect the whole flock with a spreading sore. He further bids that foolish questions and contentions be avoided. — OF THE CHRISTIAN FAITH 5, Prologue 3-4
Tito 3:10
This monster's cavern [of heresies], your sacred Majesty, is thick laid (as seafaring men do say it is) with hidden lairs, and all the surrounding neighborhood, where the rocks of unbelief echo to the howling of her black dogs, we must pass by with ears stopped up. For it is written: "Hedge your ears about with thorns" and again: "Beware of dogs. Beware of evil workers"; and yet again: "One who is a heretic, avoid after the first reproof knowing that such a one is fallen and is in sin, being condemned of his own judgment." So then, like prudent pilots, let us set the sails of our faith for the course wherein we may pass by most safely and again follow the coasts of the Scriptures. — Exposition of the Christian Faith 1.6.47
