The sacraments are “efficacious signs of grace, instituted by Christ and entrusted to the Church, by which divine life is dispensed to us” (CCC 1131). In other words, a sacrament is a sacred and visible sign that is instituted by Jesus to give us grace, an undeserved gift from God. (See also CCC 1084).
