In the Tridentine Mass form of the Roman Rite, the sign of peace is given at Solemn Masses alone and is exchanged only among the clergy (unless emperors, kings or princes were present, in which case they, too, received the greeting. If several members of a royal family were present, at least the sovereign received the greeting). It is given by extending both arms in a slight embrace with the words "Pax tecum" (Peace be with you), first by the priest celebrant to the deacon, who in turn gives it to the subdeacon, who gives the sign to any other clergy present in choir dress. During the Nuptial Solemn Mass, it is also given to the groom, who then gives the sign of peace to his bride.
