Sacraments & Liturgy
It is this mystery of Christ that the Church proclaims and celebrates in her liturgy so that the faithful may live from it and bear witness to it in the world: 'For it is in the liturgy, especially in the divine sacrifice of the Eucharist, that "the work of our redemption is accomplished," and it is through the liturgy especially that the faithful are enabled to express in their lives and manifest to others the mystery of Christ and the real nature of the true Church'* (CCC 1068).
*Sacrosanctum concilium 2.
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."*
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 (CCC 1115-1116).
