Be The Light
The sacraments are efficacious signs of grace, instituted by Christ and entrusted to the Church, by which divine life is dispensed to us. The visible rites by which the sacraments are celebrated signify and make present the graces proper to each sacrament. They bear fruit in those who receive them with the required dispositions. --Catechism of the Catholic Church, 1131
The sacraments of the New Covenant are necessary for salvation. “Sacramental grace” is the grace of the Holy Spirit, given by Christ and proper to each sacrament. The Spirit heals and transforms those who receive Him by conforming them to the Son of God.
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. --Catechism of the Catholic Church, 1134
