The Seven Sacraments of the Church
Christ instituted the sacraments of the new law. There are seven: Baptism, Confirmation (or Chrismation), the Eucharist, Penance, the Anointing of the Sick, Holy Orders and Matrimony. The seven sacraments touch all the stages and all the important moments of Christian life:1 they give birth and increase healing and mission to the Christian's life of faith. There is thus a certain resemblance between the stages of natural life and the stages of the spiritual life.
Following this analogy, the first chapter will expound the three sacraments of Christian initiation; the second, the sacraments of healing; and the third, the sacraments at the service of communion and the mission of the faithful. This order, while not the only one possible, does allow one to see that the sacraments form an organic whole in which each particular sacrament has its own vital place. In this organic whole, the Eucharist occupies a unique place as the "Sacrament of sacraments": "all the other sacraments are ordered to it as to their end."2

Sacraments of Initiation
1 - BAPTISM
In Baptism we receive new life in Christ. Baptism takes away original sin and gives us a new birth in the Holy Spirit. Its sign is the pouring of water.
2 - CONFIRMATION
Confirmation seals our life of faith in Jesus. Its signs are the laying on of hands on a person’s head, most often by a bishop, and the anointing with oil. Like Baptism, Confirmation is received only once.
3 - EUCHARIST
The Eucharist nourishes our life of faith. Its signs are the bread and wine we receive—the Body and Blood of Christ.
Sacraments of Healing
4 - PENANCE
Through Penance we receive God’s forgiveness. Forgiveness requires being sorry for our sins. In Penance we receive Jesus’ healing grace through absolution by the priest. The signs of this sacrament are our confession of sins and the words of absolution.
5 - ANOINTING OF THE SICK
This sacrament unites a sick person’s suffering with that of Jesus and brings forgiveness of sins. Oil, a symbol of strength, is the sign of this sacrament. A person is anointed with oil and receives the laying on of hands from a priest.
Sacraments at the Service of Communion
6 - MATRIMONY
In Matrimony a baptized man and woman are united with each other as a sign of the unity between Jesus and his Church. Matrimony requires the consent of the couple, as expressed in the marriage promises. The couple and their wedding rings are the signs of this sacrament.
7 - HOLY ORDERS
In Holy Orders men are ordained as priests, deacons, or bishops. Priests serve as spiritual leaders of their communities, and deacons serve to remind us of our baptismal call to help others. Bishops carry on the teachings of the apostles. The signs of this sacrament are the laying on of hands and anointing with oil by the bishop.
