Exodus 29 (chosen pages)

(Ex 29, 5-7) Take the anointing oil and anoint him

[5] Take the vestments and clothe Aaron with the tunic, the robe of the ephod, the ephod itself, and the breastpiece, fastening the embroidered belt of the ephod around him. [6] Put the miter on his head, the sacred diadem on the miter. [7] Then take the anointing oil and anoint him with it, pouring it on his head.

(CCC 436) The word "Christ" comes from the Greek translation of the Hebrew Messiah, which means "anointed". It became the name proper to Jesus only because he accomplished perfectly the divine mission that "Christ" signifies. In effect, in Israel those consecrated to God for a mission that he gave were anointed in his name. This was the case for kings, for priests and, in rare instances, for prophets (Cf. Ex 29:7; Lev 8:12; 1 Sam 9:16; 10:1; 16:1, 12-13; I Kings 1:39; 19:16). This had to be the case all the more so for the Messiah whom God would send to inaugurate his kingdom definitively (Cf. Ps 2:2; Acts 4:26-27). It was necessary that the Messiah be anointed by the Spirit of the Lord at once as king and priest, and also as prophet (Cf. Isa 11:2; 61:1; Zech 4:14; 6:13; Lk 4:16-21). Jesus fulfilled the messianic hope of Israel in his threefold office of priest, prophet and king. (CCC 1539) The chosen people was constituted by God as "a kingdom of priests and a holy nation" (Ex 19:6; cf. Isa 61:6). But within the people of Israel, God chose one of the twelve tribes, that of Levi, and set it apart for liturgical service; God himself is its inheritance (Cf. Num 1:48-53; Josh 13:33). A special rite consecrated the beginnings of the priesthood of the Old Covenant. The priests are "appointed to act on behalf of men in relation to God, to offer gifts and sacrifices for sins." (Heb 5:1; cf. Ex 29:1-30; Lev 8). (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).
