The Church as the Body of Christ — 1 Corinthians 12

1Cor 12:12-27: "for just as the body is one and has many members... so it is with Christ." By one Spirit all are baptized into one body, and the diversity of gifts serves the common good. Augustine's totus Christus — the whole Christ, head and members — expresses this unity, and Calvin treated the church as the mother of believers. The Catechism develops the body-of-Christ image for the communion of saints. The Spirit who distributes gifts here is the same Spirit of John 15:26 and Pentecost in Acts 2:17. The one baptism into one body connects to Rom 6:3 and Eph 4:4-6.
