There are seven sacraments of the Catholic Church, which were instituted by Jesus and entrusted to the Church. Sacraments are visible rites seen as signs and efficacious channels of the grace of God to all those who receive them with the proper disposition. The sevenfold list of sacraments is often organized into three groups: the sacraments of initiation (into the Church, the body of Christ), consisting of Baptism, Confirmation, and the Eucharist; the sacraments of healing, consisting of Penance and Anointing of the Sick; and the sacraments of service: Holy Orders and Matrimony.
Sacraments of Initiation are comprised of Baptism, Confirmation, and Eucharist (communion). Christian initiation is accomplished by means of the sacraments which establish the foundations of Christian life. The faithful born anew by Baptism are strengthened by Confirmation and are then nourished by the Eucharist.
The Sacraments of Healing are comprised of the sacraments of Reconciliation and Anointing of the Sick. All of us experience the need for healing. We are subject to sin, suffering, disease and death. We begin to heal by reconciling with God and receiving the prayers and holy oil for the sick and dying.
The Sacraments of Service are comprised of the sacraments of Holy Orders and Matrimony. They are directed toward the salvation of others; if they contribute as well to personal salvation, it is through service to others that they do so. They confer a particular mission in Church and serve to build up the People of God.
