Charles Ellicott Commentary 1 Peter 5:14

"Salute one another with a kiss of love. Peace be unto you all that are in Christ." — 1 Peter 5:14 (ASV)

Kiss of charity.—Not only does he wish them to receive the greetings of the Roman Church, but to display their brotherly love to each other as well. On the kiss of charity, see 1 Thessalonians 5:26. The “peace” which he wishes to them includes, though it is not limited to, peace amongst themselves.
