This document discusses the sacraments of the Catholic Church. It defines sacraments as efficacious signs of grace instituted by Christ and entrusted to the Church to dispense divine life. When celebrated, sacraments bear fruit in those who receive them by making people holy and building up the body of Christ. There are seven sacraments grouped into the categories of Christian initiation, healing, and service/communion. The sacraments are celebrated through liturgical elements like readings, gestures, and music that unfold the Church's doctrine on the sacraments.
