To Titus, my own son after the common faith: Grace, mercy, and peace, from God the Father and the Lord Jesus Christ our Savior.
All Commentaries on Titus 1:4 Go To Titus 1
John Chrysostom
AD 407
After Paul had called Titus his own son and assumed the dignity of a father, hear how it is that he lessens and lowers that honor. He adds, “After the common faith”—that means: with respect to the faith I have no advantage over you. It is common to us both. You and I were together born by it. Why then does he call him son? Either wishing to express his affection for him, or his priority in the gospel, or to show that Titus had been enlightened by him. In a similar way he calls the faithful both children and brothers. They are brothers because they were born by the same faith. They are children, because it was by his hands.
