Are efficacious signs of grace, instituted by Christ and entrusted to the Church, by which divine life is dispersed to us through the Holy Spirit. The visible rites by which the sacraments are celebrated signify and make present the graces proper to the sacrament (CCC 1131).
The Holy Spirit prepares the faithful for the sacraments by the Word of God and the faith which welcomes that word in well-disposed hearts. Thus the sacraments strengthen faith and express it (CCC 1133).
The fruit of sacramental life is both personal and ecclesial. For every one of the faithful on the one hand, this fruit is life for God in Christ Jesus, for the Church, on the other, it is an increase in charity and in her mission of witness (CCC 1134).
