"What are the Sacraments:"
-From the United States Conference of Catholic Bishops
We recognize that the Sacraments have a visible and invisible reality, a reality open to all the human senses but grasped in its God-given depths with the eyes of faith. When parents hug their children, for example, the visible reality we see is the hug. The invisible reality the hug conveys is love. We cannot "see" the love the hug expresses, though sometimes we can see its nurturing effect in the child.
The visible reality we see in the Sacraments is their outward expression, the form they take, and the way in which they are administered and received. The invisible reality we cannot "see" is God's grace, his gracious initiative in redeeming us through the death and Resurrection of his Son. His initiative is called grace because it is the free and loving gift by which he offers people a share in his life, and shows us his favor and will for our salvation. Our response to the grace of God's initiative is itself a grace or gift from God by which we can imitate Christ in our daily lives.
The saving words and deeds of Jesus Christ are the foundation of what he would communicate in the Sacraments through the ministers of the Church. 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 the Anointing of the Sick), and the Sacraments at the Service of Communion (Marriage and Holy Orders). Through the Sacraments, God shares his holiness with us so that we, in turn, can make the world holier.
Sacraments of Initiation
1212 The sacraments of Christian initiation - Baptism, Confirmation, and the Eucharist - lay the foundations of every Christian life. "The sharing in the divine nature given to men through the grace of Christ bears a certain likeness to the origin, development, and nourishing of natural life. The faithful are born anew by Baptism, strengthened by the sacrament of Confirmation, and receive in the Eucharist the food of eternal life. By means of these sacraments of Christian initiation, they thus receive in increasing measure the treasures of the divine life and advance toward the perfection of charity."

Sacraments of Vocation
THE SACRAMENT OF MATRIMONY
1601 "The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament."
THE SACRAMENT OF HOLY ORDERS
1536 Holy Orders is the sacrament through which the mission entrusted by Christ to his apostles continues to be exercised in the Church until the end of time: thus it is the sacrament of apostolic ministry. It includes three degrees: episcopate, presbyterate, and diaconate.

Sacraments of Healing
THE SACRAMENTS OF HEALING
1420 Through the sacraments of Christian initiation, man receives the new life of Christ. Now we carry this life "in earthen vessels," and it remains "hidden with Christ in God."1 We are still in our "earthly tent," subject to suffering, illness, and death.2 This new life as a child of God can be weakened and even lost by sin.
1421 The Lord Jesus Christ, physician of our souls and bodies, who forgave the sins of the paralytic and restored him to bodily health,3 has willed that his Church continue, in the power of the Holy Spirit, his work of healing and salvation, even among her own members. This is the purpose of the two sacraments of healing: the sacrament of Penance and the sacrament of Anointing of the Sick.
