Whether confirmation is a sacrament?

Objections

Objection 1 : It seems that Confirmation is not a sacrament. For sacraments derive their efficacy from the Divine institution, as stated above (Question [64], Article [2]). But we read nowhere of Confirmation being instituted by Christ. Therefore it is not a sacrament.
Objection 2 : Further, the sacraments of the New Law were foreshadowed in the Old Law; thus the Apostle says (1 Cor. 10:2-4), that "all in Moses were baptized, in the cloud and in the sea; and did all eat the same spiritual food, and all drank the same spiritual drink." But Confirmation was not foreshadowed in the old Testament. Therefore it is not a sacrament.
Objection 3 : Further, the sacraments are ordained unto man's salvation. But man can be saved without Confirmation: since children that are baptized, who die before being confirmed, are saved. Therefore Confirmation is not a sacrament.
Objection 4 : Further, by all the sacraments of the Church, man is conformed to Christ, Who is the Author of the sacraments. But man cannot be conformed to Christ by Confirmation, since we read nowhere of Christ being confirmed.
