Baptism is the sign and seal of incorporation into Christ. Presbyterians believe Baptism the beginning of life in Christ, not its completion. Both believers and their children are included in God’s covenant love. Baptism, whether administered to those who profess their faith or to those presented for Baptism as children, is one and the same sacrament. Baptism is received only once, though there may be many times throughout one’s life to reaffirm the commitments made at Baptism. As there is one body, there is one Baptism. (Eph. 4:4-6). The PCUSA recognizes all Baptisms with water in the name of the Father, of the Son, and of the Holy Spirit administered by other Christian churches. Baptism is celebrated in a service of public worship.
