Andreas of Caesarea : See how the beginning and the end of the epistle are the same. At the beginning Peter said that the Father has mercy on us through the Son and here he once again says that the Father has called us into his eternal glory through Jesus Christ. — CATENA Bede : Grace to all of you who are in Christ Jesus. He began the Epistle with grace, ended with grace, and sprinkled grace throughout, in order to condemn the Pelagian error in every part of his speech and to teach that the Church of Christ can only be saved by his grace. And thoughtfully, when he said: Grace to you, he added: To all who are in Christ Jesus, signifying that what he wrote to a few Churches, that is, to Pontus, Galatia, Cappadocia, Asia, and Bithynia, he wrote to all the Churches of Christ throughout the world. Just as John, in the Apocalypse, when he admonished the seven Churches of Asia individually as befitting each, added at the end of each, thus concluding: He who has ears to hear, let him hear what the Spirit says to the Churches (Apoc. II), plainly indicating that everything he wrote to any one Church, was written to all Churches of the faithful who have a discerning ear. — Commentary on the Catholic Epistles Clement of Alexandria ((as quoted by Cassiodorus)) : "But the God of all grace," he says. [1 Peter 5:10] "Of all grace," he says, because He is good, and the giver of all good things. — From the Latin Translation of Cassiodorus Oecumenius : But the God of all grace, who has called us to His eternal glory by Christ Jesus, after you have suffered a little while, will Himself restore, establish, strengthen, and settle you. To Him be glory and dominion forever and ever. Amen. And beginning the letter, Peter said that the Father, for the sake of the Son, have mercy on us, and now concluding, he teaches to call the same Father through the Son: for this is their aim to preach the mystery, although they do this with exhortation. — Commentary on 1 Peter
