Greet one another with a kiss of love. Peace be to you all who are in Christ Jesus. Amen.
“In the ancient world kisses were normally exchanged among family members (parents and children; brothers and sisters; servants and masters) and at times between rulers and their clients. ... The familial kiss probably forms the background to the NT practice, for all fellow-Christians were considered brothers and sisters. This affectionate kissing was normally on the cheeks, forehead, or hands. We can assume such to be the practice here. -- . In calling it the ‘kiss of love’ Peter not only brings out the meaning of kiss (‘kiss,’ philema in Greek, comes from phileo, a verb indicating familial and friendly as opposed to erotic love), but also expresses the proper relationship among the members of the Christian community (‘love’ here is the typical Christian term for love, agape, used also in 1 Peter 1:22; 1 Peter 4:8)." - Constable
