Whether it is fitting that Christ should be a priest?

Objections

Objection 1 : It would seem unfitting that Christ should be a priest. For a priest is less than an angel; whence it is written (Zach. 3:1): "The Lord showed me the high-priest standing before the angel of the Lord." But Christ is greater than the angels, according to Heb. 1:4: "Being made so much better than the angels, as He hath inherited a more excellent name than they." Therefore it is unfitting that Christ should be a priest.
Objection 2 : Further, things which were in the Old Testament were figures of Christ, according to Col. 2:17: "Which are a shadow of things to come, but the body is Christ's." But Christ was not descended from the priests of the Old Law, for the Apostle says (Heb. 7:14): "It is evident that our Lord sprang out of Judah, in which tribe Moses spoke nothing concerning priests." Therefore it is not fitting that Christ should be a priest.
Objection 3 : Further, in the Old Law, which is a figure of Christ, the lawgivers and the priests were distinct: wherefore the Lord said to Moses the lawgiver (Ex. 28:1): "Take unto thee Aaron, thy brother . . . that he [Vulg.: 'they'] may minister to Me in the priest's office." But Christ is the giver of the New Law, according to Jer. 31:33: "I will give My law in their bowels." Therefore it is unfitting that Christ should be a priest.
