Guided by the Holy Spirit, the Church recognizes the existence of Seven Sacraments instituted by the Lord. They are the Sacraments of Initiation (Baptism, Confirmation, the Eucharist), the Sacraments of Healing (Penance and Anointing of the Sick), and the Sacraments at the Service of Communion (Holy Matrimony and Holy Orders). Through the Sacraments, God shares his holiness with us so that we, in turn, can make the world holier.
According to the Second Vatican Council, “The purpose of the sacraments is to sanctify men, to build up the body of Christ, and finally, to give worship to God. Because they are signs they also instruct. They not only presuppose faith, but by words and objects they also nourish, strengthen, and express it; that is why they are called ‘sacraments of faith.’ They do indeed 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 duly, and to practice charity” (Sacred Constitution on the Liturgy, 59).
