John Gill, on Titus 1:4

“To Titus my beloved son, according to the common faith, grace and peace from God the Father, and from Christ Jesus our Saviour.”

“To Titus, mine own son after the common faith,.... Not in a natural, but in a spiritual sense; the apostle being the instrument of his conversion, as he was of the conversion of Onesimus, and of many of the Corinthians, and therefore is said to beget them, Plm 1:10 and so was their spiritual father, and they his children: Titus was, in this sense, his "own son", or a true son, a legitimate one; a true convert; one really born again; a sincere believer, an Israelite indeed: and this he was "after the common faith"; either the doctrine of faith, which is but one, and is common to all the saints; or the grace of faith, which though different in degrees, yet is alike precious faith in all; the same for nature, kind, object, operation, and effects: and this phrase is used to show in what sense Titus was son to the apostle; as he was a believer, and no otherwise. Grace, mercy, and peace, &c. which is the apostle's usual salutation; see Ti1 1:2. The word "mercy" is left out in the Claromontane copy, and in the Vulgate Latin, Syriac, and Ethiopic versions.”
