Lev 8, 6-9 He put the tunic on Aaron

(Lev 8, 6-9) He put the tunic on Aaron

[6] Bringing forward Aaron and his sons, he first washed them with water. [7] Then he put the tunic on Aaron, girded him with the sash, clothed him with the robe, placed the ephod on him, and girded him with the embroidered belt of the ephod, fastening it around him. [8] He then set the breastpiece on him, with the Urim and Thummim in it, [9] and put the miter on his head, attaching the gold plate, the sacred diadem, over the front of the miter, at his forehead, as the LORD had commanded him to do.

(CCC 1540) Instituted to proclaim the Word of God and to restore communion with God by sacrifices and prayer (Cf. Mal 2:7-9), this priesthood nevertheless remains powerless to bring about salvation, needing to repeat its sacrifices ceaselessly and being unable to achieve a definitive sanctification, which only the sacrifice of Christ would accomplish (Cf. Heb 5:3; 7:27; 10:1-4).
