Young Kissing Girls

Kiss of peace
Nyrop notes that the kiss was used as an expression of deep, spiritual love in the primitive Christian Church. Christ said, for instance, "Peace be with you, my peace I give you," and the members of Christ's Church gave each other peace symbolically through a kiss. St Paul repeatedly speaks of the "holy kiss", and, in his Epistle to the Romans, writes: " Salute one another with an holy kiss" and his first Epistle to the Thessalonians (1 Th 5.26), he says : "Greet all the brethren with an holy kiss."
The holy kiss was also used in secular festivities. During the Middle Ages, for example, Nyrop points out that it was the custom to "seal the reconciliation and pacification of enemies by a kiss." Even knights gave each other the kiss of peace before proceeding to the combat, and forgave one another all real or imaginary wrongs. The holy kiss was also found in the ritual of the Church on solemn occasions, such as baptism, marriage, confession, ordination, or obsequies. However, toward the end of the Middle Ages the kiss of peace disappears as the official token of reconciliation.
