4 To Titus, my own son, according to the common faith. Hence it is evident in what sense a minister of the word is said to beget spiritually those whom he brings to the obedience of Christ, that is, so that he himself is also begotten. Paul declares himself to be the father of Titus, with respect to his faith; but immediately adds, that this faith is common to both, so that both of them alike have the same Father in heaven. Accordingly, God does not diminish his own prerogative, when he pronounces those to be spiritual fathers along with himself, by whose ministry he regenerates whom he chooses; for of themselves they do nothing, but only by the efficacy of the Spirit. As to the remainder of the verse, the exposition of it will be found in the Commentaries on the former Epistles, and especially on the First Epistle to Timothy. (213)
