Baptism is the foundation for all future church participation and ministry. It is full initiation by water and the Holy Spirit into Christ's Body, and the Church. God establishes an indissoluble bond with each person in Baptism. God adopts us, making us members of the church and inheritors of the Kingdom of God (BCP, pp. 298, 858).
In baptism we are made sharers in the new life of the Holy Spirit. During the baptismal rite the members of the congregation promise to do all they can to support the candidates for baptism in their life in Christ. The newly baptized is "sealed by the Holy Spirit in Baptism and marked as Christ's own for ever." The Catechism notes that "Infants are baptized so that they can share citizenship in the Covenant, membership in Christ, and redemption by God." The baptismal promises are made for infants by their parents or sponsors, "who guarantee that the infants will be brought up within the Church, to know Christ and be able to follow him" (BCP, pp. 858-859).
