Reply Obj. 2: Holiness is the cause of salvation. Therefore it comes to the same whether we say "chrism of salvation" or "of sanctification."
Reply Obj. 3: Baptism is the regeneration unto the spiritual life, whereby man lives in himself. And therefore in the baptismal form that action alone is expressed which refers to the man to be sanctified. But this sacrament is ordained not only to the sanctification of man in himself, but also to strengthen him in his outward combat. Consequently not only is mention made of interior sanctification, in the words, "I confirm thee with the chrism of salvation": but furthermore man is signed outwardly, as it were with the standard of the cross, unto the outward spiritual combat; and this is signified by the words, "I sign thee with the sign of the cross."
But in the very word "baptize," which signifies "to cleanse," we can understand both the matter, which is the cleansing water, and the effect, which is salvation. Whereas these are not understood by the word "confirm"; and consequently they had to be expressed.
Again, it has been said above (Q. 66, A. 5, ad 1) that the pronoun "I" is not necessary to the Baptismal form, because it is included in the first person of the verb. It is, however, included in order to express the intention. But this does not seem so necessary in Confirmation, which is conferred only by a minister of excellence, as we shall state later on (A. 11). _______________________
FIFTH ARTICLE [III, Q. 72, Art. 5]
Whether the Sacrament of Confirmation Imprints a Character?
Objection 1: It seems that the sacrament of Confirmation does not imprint a character. For a character means a distinctive sign. But a man is not distinguished from unbelievers by the sacrament of Confirmation, for this is the effect of Baptism; nor from the rest of the faithful, because this sacrament is ordained to the spiritual combat, which is enjoined to all the faithful. Therefore a character is not imprinted in this sacrament.
Obj. 2: Further, it was stated above (Q. 63, A. 2) that a character is a spiritual power. Now a power must be either active or passive. But the active power in the sacraments is conferred by the sacrament of order: while the passive or receptive power is conferred by the sacrament of Baptism. Therefore no character is imprinted by the sacrament of Confirmation.
Obj. 3: Further, in circumcision, which is a character of the body, no spiritual character is imprinted. But in this sacrament a character is imprinted on the body, when the sign of the cross is signed with chrism on man's brow. Therefore a spiritual character is not imprinted by this sacrament.
On the contrary, A character is imprinted in every sacrament that is not repeated. But this sacrament is not repeated: for Gregory II says (Ep. iv ad Bonifac.): "As to the man who was confirmed a second time by a bishop, such a repetition must be forbidden." Therefore a character is imprinted in Confirmation.
