CCC 462

The Letter to the Hebrews refers to the same mystery:

Consequently, when Christ came into the world, he said, "Sacrifices and offerings you have not desired, but a body have you prepared for me; in burnt offerings and sin offerings you have taken no pleasure. Then I said, Lo, I have come to do your will, O God."⁸⁴ Heb 10:5-7, citing Ps 40:6-8 (7-9 LXX).
