We Are One Body in Christ

12 . Regenerated as "Children in the Son", the baptized are inseparably joined together as "members of Christ and members of the body of the Church", as the Council of Florence teaches(17).

Baptism symbolizes and brings about a mystical but real incorporation into the crucified and glorious body of Christ. Through the sacrament Jesus unites the baptized to his death so as to unite the recipient to his resurrection (cf. Rom 6:3-5). The "old man" is stripped away for a reclothing with "the new man", that is, with Jesus himself: "For as many of you as were baptized into Christ have put on Christ" (Gal 3:27; cf. Eph 4:22-24; Col 3:9-10). The result is that "we, though many, are one body in Christ" (Rom 12:5).

In the words of Saint Paul we find again the faithful echo of the teaching of Jesus himself, which reveals the mystical unity of Christ with his disciples and the disciples with each other, presenting it as an image and extension of that mystical communion that binds the Father to the Son and the Son to the Father in the bond of love, the Holy Spirit (cf. Jn 17:21). Jesus refers to this same unity in the image of the vine and the branches: "I am the vine, you the branches" (Jn 15:5), an image that sheds light not only on the deep intimacy of the disciples with Jesus but on the necessity of a vital communion of the disciples with each other: all are branches of a single vine.
