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. (From USCCB Website)
Sacrament of Baptism Holy Baptism is the basis of the whole Christian life, the gateway to life in the spirit, and the door which gives access to the other sacraments. Through baptism we are freed from sin and reborn as sons of god; we become members of Christ, are incorporated into the Church and made sharers in her mission: "Baptism is the sacrament of regeneration through water in the word."
Sacrament of Confirmation Confirmation deepens our baptismal life that calls us to be missionary witnesses of Jesus Christ in our families, neighborhoods, society, and the world. . . . We receive the message of faith in a deeper and more intensive manner with great emphasis given to the person of Jesus Christ, who asked the Father to give the Holy Spirit to the Church for building up the community in loving service.
Sacrament of the Eucharist In the celebration of the Eucharist, bread and wine become the Body and Blood of Jesus Christ through the power of the Holy Spirit and the instrumentality of the priest. The whole Christ is truly present -- body, blood, soul, and divinity -- under the appearances of bread and wine, the glorified Christ who rose from the dead. This is what the Church means when she speaks of the "Real Presence" of Christ in the Eucharist. The transformed bread and wine are truly the Body and Blood of Christ and are not merely symbols. When Christ said “This is my body” and “This is my blood,” the bread and wine are transubstantiated. Though the bread and wine appear the same to our human faculties, they are actually the real body and blood of Jesus.
Sacrament of Penance Not only does it [the Sacrament of Penance] free us from our sins but it also challenges us to have the same kind of compassion and forgiveness for those who sin against us. We are liberated to be forgivers. We obtain new insight into the words of the Prayer of St. Francis: "It is in pardoning that we are pardoned." Jesus entrusted the ministry of reconciliation to the Church. The Sacrament of Penance is God's gift to us so that any sin committed after Baptism can be forgiven. In confession we have the opportunity to repent and recover the grace of friendship with God. It is a holy moment in which we place ourselves in his presence and honestly acknowledge our sins, especially mortal sins. With absolution, we are reconciled to God and the Church. The Sacrament helps us stay close to the truth that we cannot live without God. "In him we live and move and have our being" (Acts 17:28).
Sacrament of Anointing of the Sick The Rite of Anointing tells us there is no need to wait until a person is at the point of death to receive the Sacrament. A careful judgment about the serious nature of the illness is sufficient. When the Sacrament of Anointing of the Sick is given, the hoped-for effect is that, if it be God's will, the person be physically healed of illness. But even if there is no physical healing, the primary effect of the Sacrament is a spiritual healing by which the sick person receives the Holy Spirit's gift of peace and courage to deal with the difficulties that accompany serious illness or the frailty of old age.
Sacrament of Marriage Man and woman were created for each other. By their marriage, the couple witnesses Christ's spousal love for the Church. One of the Nuptial Blessings in the liturgical celebration of marriage refers to this in saying, "Father, you have made the union of man and wife so holy a mystery that it symbolizes the marriage of Christ and his Church." The Sacrament of Marriage is a covenant, which is more than a contract. Covenant always expresses a relationship between persons. The marriage covenant refers to the relationship between the husband and wife, a permanent union of persons capable of knowing and loving each other and God. The celebration of marriage is also a liturgical act, appropriately held in a public liturgy at church. Catholics are urged to celebrate their marriage within the Eucharistic Liturgy.
Sacrament of Holy Orders From the moment of Jesus' conception in the womb of Mary until his Resurrection, he was filled with the Holy Spirit. In biblical language, he was anointed by the Holy Spirit and thus established by God the Father as our high priest. As Risen Lord, he remains our high priest. . . . While all the baptized share in Christ's priesthood, the ministerial priesthood shares this through the Sacrament of Holy Orders in a special way. Ordination to the priesthood is always a call and a gift from God. Christ reminded his Apostles that they needed to ask the Lord of the harvest to send laborers into the harvest. Those who seek priesthood respond generously to God's call using the words of the prophet, "Here I am, send me" (Is 6:8). This call from God can be recognized and understood from the daily signs that disclose his will to those in charge of discerning the vocation of the candidate.
