Bede : Through Sylvanus, your faithful brother, etc. What he says, beseeching, can refer to what precedes, because he writes briefly after all, not commanding, but beseeching them to stand firm in faith. It can also be rightly connected to what follows, so that it is understood that he not only testifies that this is their true grace which he declares by writing, since indeed there is no other in whom we must be saved (Acts IV), but also urges them to make this their true grace which they have been imbued with in Christ. For the grace of Christ becomes their grace, who accept it with a pure heart. For he who despises the grace of God does not diminish grace itself, but makes it not his own, that is, makes it to not benefit himself. — Commentary on the Catholic Epistles Oecumenius : "By Silvanus." This Silvanus was very faithful and eagerly motivated around the preaching. Indeed, Paul also mentions him and takes him as a helper along with Timothy in his letters, saying: "Paul, and Silvanus, and Timothy." (1-2 Thess. 1:1) — Commentary on 1 Peter
