1Tim 2, 5-7 There is one mediator Christ Jesus

(1Tim 2, 5-7) There is one mediator Christ Jesus

[5] For there is one God. There is also one mediator between God and the human race, Christ Jesus, himself human, [6] who gave himself as ransom for all. This was the testimony at the proper time. [7] For this I was appointed preacher and apostle (I am speaking the truth, I am not lying), teacher of the Gentiles in faith and truth.

(CCC 618) The cross is the unique sacrifice of Christ, the "one mediator between God and men" (1 Tim 2:5). But because in his incarnate divine person he has in some way united himself to every man, "the possibility of being made partners, in a way known to God, in the paschal mystery" is offered to all men (GS 22 § 5; cf. § 2). He calls his disciples to "take up [their] cross and follow [him]" (Mt 16:24), for "Christ also suffered for [us], leaving [us] an example so that [we] should follow in his steps" (1 Pt 2:21). In fact Jesus desires to associate with his redeeming sacrifice those who were to be its first beneficiaries (Cf. Mk 10:39; Jn 21:18-19; Col 1:24). This is achieved supremely in the case of his mother, who was associated more intimately than any other person in the mystery of his redemptive suffering (Cf. Lk 2:35). Apart from the cross there is no other ladder by which we may get to heaven (St. Rose of Lima: cf. P. Hansen, Vita mirabilis (Louvain, 1668). (CCC 1544) Everything that the priesthood of the Old Covenant prefigured finds its fulfillment in Christ Jesus, the "one mediator between God and men" (2 Tim 2:5). The Christian tradition considers Melchizedek, "priest of God Most High," as a prefiguration of the priesthood of Christ, the unique "high priest after the order of Melchizedek" (Heb 5:10; cf. 6:20; Gen 14:18); "holy, blameless, unstained" (Heb 7:26), "by a single offering he has perfected for all time those who are sanctified" (Heb 10:14), that is, by the unique sacrifice of the cross. (CCC 2574) Once the promise begins to be fulfilled (Passover, the Exodus, the gift of the Law, and the ratification of the covenant), the prayer of Moses becomes the most striking example of intercessory prayer, which will be fulfilled in "the one mediator between God and men, the man Christ Jesus" (1 Tim 2:5).
