Jas 5:19

“My brothers, if anyone among you strays from the truth, etc. For, as in the earlier sections of this Epistle, our tongue is restrained from wicked or idle speech, it is now shown what we should especially speak at the end. Therefore, we are commanded to pray and sing psalms to the Lord whenever we are struck by adversities. Likewise, we must confess our sins to one another and pray for each other, so that we may be saved, showing as much care as we can for the health of our neighbors, not only their temporal but rather their eternal health. For just as it is of great reward to save a body destined to die, how much more meritorious is it to save a soul destined to live forever in the heavenly homeland? It should be noted that some codices have: "He will save his own soul from death." And from the ambiguous Greek, it can also be rightly interpreted this way. Indeed, whoever corrects a stray person thereby secures for themselves greater joys of celestial life. He says, "He will save his own soul from death and will cover a multitude of sins." He who converts a sinner from error hides his sins from the view of the inner Judge by the superposition of a better life; and he also covers his own failings, in whatever ways he has erred, from the sight of Him who sees all things by caring for his neighbor, according to the Psalmist: "Blessed are those whose iniquities are forgiven, and whose sins are covered" (Psalm 31). And Blessed James, urging this, does not forget what he said earlier: "Do not become many teachers, my brothers" (James 3). For there, he removes the imperfect from the office of teaching, which they sought out of pride. Here, however, he instructs those who are well-prepared on what they ought to do for the salvation of their neighbors out of fraternal love. For what a teacher is said to do here, elsewhere charity is remembered to do, according to Blessed Peter the apostle: "Because charity covers a multitude of sins" (1 Peter 4). Nor should it be overlooked that this conversion of the erring is often accomplished not only by speaking but also frequently by acting well. For if anyone shows good examples of action to their neighbors, even without speaking, and converts them to works of alms, hospitality, or other virtues they had neglected, they indeed perform the office of a teacher and will receive a certain reward from the merciful Judge for the salvation of the brother they corrected.”

“Jeremiah says the same: "If you bring forth the honorable from the unworthy, you shall be as My mouth" ("and if you extract the precious from the worthless, you shall be as My mouth") (Jer. 15:19), for everyone who proclaims the words of God becomes the mouth of God. For what does He say? "It is not you who speak, but the Spirit of your Father who speaks in you" (Matt. 10:20). Therefore through David He also forbids the sinner to declare His ordinances (Ps. 50:16).”

“Brothers, if anyone among you has strayed from the truth and someone turns him back, let him know that whoever turns a sinner from the error of his way will save his soul from death and will cover a multitude of sins. "someone turns him back, let him know." For it is necessary to serve the salvation of one's neighbor. "whoever turns a sinner from the error of his way." This is also said by Jeremiah: "And if you separate the precious from the vile, you will be as my mouth." (Jer. 15:12) For whoever announces His words becomes the mouth of God. "For it is not you who speak," He says, "but the Spirit of my Father who speaks in you." (Matt. 10:19) Therefore, He also forbids the sinner, through David (Ps. 49:16), not to declare his justifications, and to take the covenant upon his lips. on the Epistles of Peter This letter is written by Peter to the Jews who had become Christians and were dispersed in various places, teaching them. For he confirms those who believed from among the Jews. First, he narrates and shows that faith in Christ was announced by the prophets, and that the redemption which would come through His blood was signified by them: and that all things to which angels desire to look have been announced to them and the Gentiles. Then, having urged them to conduct themselves worthily toward Him who called them, Peter exhorts them to honor even kings and commands harmony among women and men, and after briefly encouraging them regarding morals, he signifies that a preaching of salvation and resurrection was also made by the Lord in Hades: so that those who had previously died might indeed rise and be judged in the body, but through the grace of resurrection may persevere. And that the end of all things is imminent, and all should be prepared, as if to give an account to the Judge: and thus Peter concludes the letter.”
