"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
All seven sacraments were established by Jesus Christ during His ministry and have been in use by the Church from its inception. The sacraments provide grace, from the sacrificial death of Christ on the Cross, to the faithful throughout their lives, from birth to death. Reception of the sacraments in accord with the teaching of the Church is the ordinary means of salvation for all the faithful.
