The Sacrament of Baptism has made you a temple of the Holy Spirit; do not cause such a great guest to flee because of your poor conduct; do not put yourself again into slavery of the devil, for the price by which you were ransomed is the blood of Christ. He ransomed you out of mercy, but he will judge you in the truth of he who reigns with the Father and the Holy Spirit forever and ever. Amen.
