CIC 1293 In treating the rite of Confirmation, it is fitting to consider the sign of anointing and what it signifies and imprints: a spiritual seal.
Anointing, in Biblical and other ancient symbolism, is rich in meaning: oil is a sign of abundance and joy;1 it cleanses (anointing before and after a bath) and limbers (the anointing of athletes and wrestlers); oil is a sign of healing, since it is soothing to bruises and wounds;2 and it makes radiant with beauty, health, and strength.
1 Cf. Deut 11:14; Pss 23:5; 104:15.
2 Cf. Isa 1:6; Lk 1034.
