“Holy Baptism is full initiation by water and the Holy Spirit into Christ’s Body, the Church”
(Book of Common Prayer, p. 298).
In the waters of baptism we are lovingly adopted by God into God’s family, which we call the Church, and given God’s own life to share and reminded that nothing can separate us from God’s love in Christ.
The Rite of Holy Baptism can be found on pp. 297-308 of the Book of Common Prayer.
