THE SACRAMENTS OF CHRISTIAN INITIATION
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." (CCC 1212)
THE SACRAMENTS OF HEALING
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." We are still in our "earthly tent," subject to suffering, illness, and death. This new life as a child of God can be weakened and even lost by sin.
The Lord Jesus Christ, physician of our souls and bodies, who forgave the sins of the paralytic and restored him to bodily health, 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. (CCC 1420-21)
THE SACRAMENTS AT THE SERVICE OF COMMUNION
Baptism, Confirmation, and Eucharist are sacraments of Christian initiation. They ground the common vocation of all Christ's disciples, a vocation to holiness and to the mission of evangelizing the world. They confer the graces needed for the life according to the Spirit during this life as pilgrims on the march towards the homeland.
Two other sacraments, Holy Orders and Matrimony, are directed towards 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 the Church and serve to build up the People of God.
Through these sacraments those already consecrated by Baptism and Confirmation for the common priesthood of all the faithful can receive particular consecrations. Those who receive the sacrament of Holy Orders are consecrated in Christ's name "to feed the Church by the word and grace of God." On their part, "Christian spouses are fortified and, as it were, consecrated for the duties and dignity of their state by a special sacrament." (CCC 1533-35)
