The seven sacraments—Baptism, Confirmation, Holy Communion, Confession, Marriage, Holy Orders, and the Anointing of the Sick—are the life of the Catholic Church. Each sacrament is an outward sign of an inward grace. When we participate in them worthily, each provides us with graces—with the life of God in our soul. In worship, we give to God that which we owe Him; in the sacraments, He gives us the graces necessary to live a truly human life.
