John Chrysostom : "This is a faithful saying," that is, it is true that godliness is profitable both here and hereafter. Observe how everywhere he brings in this, he needs no demonstration, but simply declares it, for he was addressing Timothy. So then even here, we have good hopes? For he who is conscious to himself of no evil, and who has been fruitful in good, rejoices even here: as the wicked man on the other hand is punished here as well as hereafter. He lives in perpetual fear, he can look no one in the face with confidence, he is pale, trembling, and full of anxiety. Is it not so with the fraudulent, and with thieves, who have no satisfaction even in what they possess? Is not the life of murderers and adulterers most wretched, who look upon the sun itself with suspicion? Is this to be called life? No; rather a horrid death! — Homily on 1 Timothy 12 Oecumenius : This is a faithful saying and worthy of all acceptance. For to this end we both labor and suffer criticism, because we trust in the living God, who is the Savior of all, especially of those who believe. This is a faithful saying and worthy of all acceptance. What kind? The one that gives life both here and there. And see that you yourself are also trustworthy, as if true, and acceptable to all; for in some things you are truly so, but in others doubtful. But because of the courage of the disciple, Paul speaks clearly throughout the entire Epistle. For to this end we both labor and suffer criticism. For what purpose? "because we trust in the living God." And we too labor readily to be conscious of this, and for this very reason our enemies especially wage war against us. who is the Savior of all. He is the Savior of all here. But here, not of all, but of those worthy to be saved. And here, He especially cares for the faithful. For even though we are fought against by so many, we are saved. Paul encourages Timothy into dangers for the sake of the faith, having God as Savior. Concerning his care, and that of the Church. — COMMENTARY ON 1 TIMOTHY
