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. There are seven sacraments: Baptism, Confirmation, Holy Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony.
Sacramental grace is the grace of the Holy Spirit which is given by Christ and is proper to each sacrament. This grace helps the faithful in their journey toward holiness and so assists the Church as well to grow in charity and in her witness to the world.
