The liturgical life of the Catholic Church revolves around the sacraments.

There are seven sacraments in the Church: Baptism, Confirmation, Eucharist, Penance, Anointing of the Sick, Matrimony, and Holy Orders.

The purpose of the sacraments is to make people holy, to build up the body of Christ, and finally, to give worship to God; but being signs, they also have a teaching function. They not only presuppose faith, but by words and object, they also nourish, strengthen, and express it; that is why they are called "sacraments of faith." The sacraments impart grace, but, in addition, the very act of celebrating them disposes the faithful most effectively to receive this grace in a fruitful manner, to worship God rightly, and to practice charity.

Worship is integral to our lives as Christians. When we engage in the prayer and ritual of the Church, we are formed as Church. Our sacramental rites are of primary importance while we are gathered.

The history of human salvation is the history of the way God came to men. The first step on this way was the bridging of the gulf separating God and man in the person of the one Mediator Jesus Christ and by his work of redemption. By means of his Church Christ makes his grace available to all. Only in this application of redemption to mankind is the redemptive action of Christ completed. The doctrine of the sacraments is the doctrine of the second part of God's way of salvation to us. It deals with the holy signs which Christ instituted as the vehicles of his grace.
