1Pet 5:14

“May I enjoy your prayers! Pray ye that may attain to Jesus. I commend unto you the Church which is at Antioch. The Churches of Philippi, whence also I write to you, salute you. Philo, your deacon, to whom also I give thanks as one who has zealously ministered to me in all things, salutes you. Agathopus, the deacon from Syria, who follows me in Christ, salutes you. "Salute ye one another with a holy kiss." I salute you all, both male and female, who are in Christ. Fare ye well in body, and soul, and in one Spirit; and do not ye forget me. The Lord be with you!”

“But when is peace more to be concluded with brethren than when, at the time of some religious observance, our prayer ascends with more acceptability; that they may themselves participate in our observance, and thereby be mollified for transacting with their brother touching. their own peace? What prayer is complete if divorced from the "holy kiss? " Whom does peace impede when rendering service to his Lord? What kind of sacrifice is that from which men depart without peace? Whatever our prayer be, it will not be better than the observance of the precept by which we are bidden to conceal our fasts; for now, by abstinence from the kiss, we are known to be fasting.”

“Greet one another with a holy kiss. With a holy kiss, a true kiss, a peaceful kiss, a dove-like kiss, not deceitful, not polluted, like the one Joab used to kill Amasa, like the one Judas used to betray the Savior, like those who speak peace with their neighbor, but evil is in their hearts (Psalm 27). Therefore, they greet one another with a holy kiss, who do not love in word or tongue, but in deed and truth.”

“Whereas Paul writes (Rom. 16:16; 1 Cor. 16:20) that believers should greet one another "with a holy kiss," Peter says: greet one another "with a kiss of love." But the thought of both is one and the same. Paul knows that love in the Lord is greater than all virtues, even martyrdom for Christ, and therefore calls holy the kiss that is given in God. And Peter, when he speaks of a kiss of love, means: of true love.”

“He speaks not of the ordinary, human peace, but wishes them to receive that peace which Christ bestowed upon them when He was departing to His sufferings, saying: "Peace I leave with you," and noting the distinction: "not as the world gives" (Jn. 14:27). For one must keep peace not out of partiality, but because you are bound by love, so that one must endure blows from adversaries. The disciples of the Lord everywhere, at the end of their epistles, append a prayer like a seal, and thereby show their genuine holiness. Some of those who came before us thought that the Mark of whom holy Peter speaks was his son also according to the flesh. They based this conjecture on the fact that in the Acts of the Apostles Luke says that after the angel of God miraculously freed the apostle Peter from the prison in which he had been placed by Herod, and ceased guiding him, he, the apostle Peter, "came to the house of Mary the mother of John, who was called Mark" (Acts 12:12). They supposed that he had come to his own house and to his lawful wife.”

“However, when Paul writes that they should greet each other with a holy kiss (2 Cor. 14:12), Peter says here, "With a kiss of love," saying the same as that. For Paul (1 Cor. 13:1-19) knows the love which is according to Christ and is greater than all virtues, even than martyrdom itself suffered for Christ. Therefore, he calls the holy kiss separate and defined in God, while he similarly refers to the kiss of love which is true love, which Paul has praised. Therefore, he also adds: "Peace to you all who are in Christ Jesus:" not speaking of the common peace which is among men, which is dear to men because of the affection for vain glory and the enjoyment of pleasures, to which those who are free from war surrender themselves; but Peter prays that they may attain the peace which Christ himself agreed to grant them as he proceeded to passion, saying: "My peace I leave with you;" and adding a distinction: "Not as the world gives." (Jn. 14:27) For peace is not to be sought because of affection, but that we may be united in love, in order to receive in this way the blows of adversaries. Moreover, the disciples of the Lord, adding as it were a seal, bring a prayer at the end, as a genuine sign of their holiness. (It was written from the city of Rome.)”
