the Institution of Confirmation by Christ (cont.) C. The Apostles acted in the mandate of Christ, seeing themselves as ministers of Christ and the dispensers of the mysteries of God

St. Thomas Aquinas on the institution of the Sacrament: “Christ instituted the Sacrament of Confirmation in such a manner that He Himself did not administer it, but that He merely promised its administration for the future, because in the Sacrament the fullness of the Holy Spirit is conferred, which was not to be given before His Resurrection and Ascension. Thus, Christ did institute the sacrament, though He never Himself administered it.”
