Baptism is one of the Seven Sacraments of the Christian Church; the first sacrament, the door of the sacraments, and the door of the Church.

Holy Baptism holds the first place among the sacraments, because it is the door of the spiritual life; for by it we are made members of Christ and incorporated with the Church. The matter of this sacrament is true and natural water.

Baptism is the sacrament of regeneration by water in the word; the external ablution of the body, performed with the prescribed form of words.
