The Church As Sign and Instrument of Salvation

9. The first beneficiary of salvation is the Church. Christ won the Church for himself at the price of his own blood and made the Church his co-worker in the salvation of the world. Indeed, Christ dwells within the Church. She is his Bride. It is he who causes her to grow. He carries out his mission through her.

The Council makes frequent reference to the Church's role in the salvation of mankind. While acknowledging that God loves all people and grants them the possibility of being saved (cf. l Tm 2:4),¹⁵ the Church believes that God has established Christ as the one mediator and that she herself has been established as the universal sacrament of salvation. ¹⁶ "To this catholic unity of the people of God, therefore,...all are called, and they belong to it or are ordered to it in various ways, whether they be Catholic faithful or others who believe in Christ or finally all people everywhere who by the grace of God are called to salvation."¹⁷ It is necessary to keep these two truths together, namely, the real possibility of salvation in Christ for all mankind and the necessity of the Church for salvation. Both these truths help us to understand the one mystery of salvation, so that we can come to know God's mercy and our own responsibility. Salvation, which always remains a gift of the Holy Spirit, requires man's cooperation, both to save himself and to save others. This is God's will, and this is why he established the Church and made her a part of his plan of salvation. Referring to "this messianic people," the Council says; "It has been set up by Christ as a communion of life, love and truth; by him too it is taken up as the instrument of salvation for all, and sent on a mission to the whole world as the light of the world and the salt of the earth."¹⁸
