Jesus gave us the Sacraments to call us to worship God, to build up the Church, to deepen our faith, to show us how to pray, to connect us with the living Tradition of the Church, and to sanctify us. While God works primarily through the sacraments, He also touches us through the community of the Church, through the lives of holy people, through prayer, spirituality, and acts of love. But "for believers, the sacraments of the New Covenant are necessary for salvation....The fruit of the sacramental life is that the Spirit of adoption makes the faithful partakers of the divine nature" (CCC, no.1129)
“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, no 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” (CCC, no. 1117)
