“‘Adhering to the teaching of the Holy Scriptures, to the apostolic traditions, and to the consensus… of the Fathers,’ we profess that ‘the sacraments of the new law were… all instituted by Jesus Christ our Lord’” (Catechism of the Catholic Church 1114; see also Council of Trent, Session 7, Introduction, and Canon 1).
“Sacraments are ‘powers that comes forth’ from the Body of Christ, which is ever-living and life-giving. They are actions of the Holy Spirit at work in his Body, the Church. They are ‘the masterworks of God’ in the new and everlasting covenant” (Catechism of the Catholic Church 1116).
“As she has done for the canon of Sacred Scripture and for the doctrine of the faith, the Church, by the power of the Spirit who guides her ‘into all truth,’ has gradually recognized this treasure received from Christ and, as the faithful steward of God’s mysteries, has determined its ‘dispensation.’ Thus the Church has discerned over the centuries that among liturgical celebrations there are seven that are, in the strict sense of the term, sacraments instituted by the Lord” (Catechism of the Catholic Church 1117).
“Jesus’ words and actions during his hidden life and public ministry were already salvific, for they anticipated the power of his Paschal mystery. They announced and prepared what he was going to give the Church when all was accomplished. The mysteries of Christ’s life are the foundations of what he would henceforth dispense in the sacraments, through the ministers of his Church, for ‘what was visible in our Savior has passed over into his mysteries’” (Catechism of the Catholic Church 1115; see also St. Leo the Great, Sermon 74).
