Q. 165. What is baptism?

A.
Baptism is a sacrament of the New Testament, wherein Christ hath ordained the washing with water in the name of the Father, and of the Son, and of the Holy Ghost,[1058] to be a sign and seal of ingrafting into himself,[1059] of remission of sins by his blood,[1060] and regeneration by his Spirit;[1061] of adoption,[1062] and resurrection unto everlasting life;[1063] and whereby the parties baptized are solemnly admitted into the visible church,[1064] and enter into an open and professed engagement to be wholly and only the Lord’s.[1065]
