Incorporated into the Church, the Body of Christ
Baptism makes us members of the Body of Christ: "Therefore . . . We are members one of another." Baptism incorporates us into the Church. From the baptismal fonts is born the one People of God of the New Covenant, which transcends all the natural or human limits of nations, cultures, races, and sexes: "For by one Spirit we were all baptized into one body."
