Lev 16, 15-16 He shall make atonement for the sanctuary

(Lev 16, 15-16) He shall make atonement for the sanctuary

[15] "Then he shall slaughter the people's sin-offering goat, and bringing its blood inside the veil, he shall do with it as he did with the bullock's blood, sprinkling it on the propitiatory and before it. [16] Thus he shall make atonement for the sanctuary because of all the sinful defilements and faults of the Israelites. He shall do the same for the meeting tent, which is set up among them in the midst of their uncleanness.

(CCC 613) Christ's death is both the Paschal sacrifice that accomplishes the definitive redemption of men, through "the Lamb of God, who takes away the sin of the world" (Jn 1:29; cf. 8:34-36; 1 Cor 5:7; 1 Pt 1:19), and the sacrifice of the New Covenant, which restores man to communion with God by reconciling him to God through the "blood of the covenant, which was poured out for many for the forgiveness of sins" (Mt 26:28; cf. Ex 24:8; Lev 16:15-16; 1 Cor 11:25). (CCC 614) This sacrifice of Christ is unique; it completes and surpasses all other sacrifices (Cf. Heb 10:10). First, it is a gift from God the Father himself, for the Father handed his Son over to sinners in order to reconcile us with himself. At the same time it is the offering of the Son of God made man, who in freedom and love offered his life to his Father through the Holy Spirit in reparation for our disobedience (Cf. Jn 10:17-18, 15:13; Heb 9:14; 1 Jn 4:10).
