20. Therefore read that the three witnesses in baptism, the water, the blood, and the Spirit, 1 John v. 7. are one, for if you take away one of these, the Sacrament of Baptism does not exist. For what is water without the cross of Christ? A common element, without any sacramental effect. Nor, again, is there the Sacrament of Regeneration without water: “For except a man be born again of water and of the Spirit, he cannot enter into the kingdom of God.” S. John iii. 5. Now, even the catechumen believes in the cross of the Lord Jesus, wherewith he too is signed; but unless he be baptized in the Name of the Father, and of the Son, and of the Holy Spirit, he cannot receive remission of sins nor gain the gift of spiritual grace.
