The seven sacraments are essential to the Catholic faith and to being Catholic. Sacraments are the Mysteries of our faith celebrated – our participation in the realities which we profess in the Creed. The sacraments are our immersion in the life of grace, they graft us as branches into the vine of Christ, they provide us grace to live the virtues, and are the remedy for the sickness of sin. There is an ebb and flow between the public prayer of the Church (sacraments/liturgy), and our private prayer life. Each nourishes the other.
The sacraments, instituted by Christ and entrusted to the Church, are efficacious signs of grace perceptible to the senses. Through them divine life is bestowed upon us (CCCC 224). Another classic definition of a sacrament: an outward sign, instituted by Christ, to give grace.
The sacramental economy consists in the communication of the fruits of Christ’s redemption through the celebration of the sacraments of the Church, most especially that of the Eucharist, “until he comes” (1 Corinthians 11:26). (CCCC 220) The mysteries of Christ’s life are the foundations of what he would henceforth dispense in the sacraments, through the ministers of His Church. (CCC 1115) As Pope St. Leo the Great said, “What was visible in our Savior has passed over into His mysteries.”
