Sacraments
The whole liturgical life of the Church revolves around the Eucharistic sacrifice and the sacraments. There are seven sacraments in the Church: Baptism, Confirmation or Chrismation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony.
Sacraments are "powers that comes forth" from the Body of Christ, which is ever-living and life-giving. They are actions of the Holy Spirit at work in his Body, the Church. They are "the masterworks of God" in the new and everlasting covenant.
The sacraments are efficacious signs of grace, instituted by Christ and entrusted to the Church, by which divine life is dispensed to us. The visible rites by which the sacraments are celebrated signify and make present the graces proper to each sacrament. They bear fruit in those who receive them with the required dispositions.
Catechism of the Catholic Church 1113, 1116, 1131.
Baptism
Holy Baptism is the basis of the whole Christian life, … 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..."
- Roman Catechism II,2,5
Reconciliation
Reconciliation is a sacrament of healing. Reconciliation enables us to receive God's unconditional love and forgiveness.
Confirmation
At Confirmation we are sealed with the Holy Spirit, who strengthens and guides our Christian faith.
Holy Communion
In the Eucharist, Jesus gives himself completely to us. Jesus becomes the spiritual food we need for life's journey.
Marriage
"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." CIC, can. 1055 § 1; cf. GS 48 § 1.
Anointing of the Sick
"By the sacred anointing of the sick and the prayer of the priests the whole Church commends those who are ill to the suffering and glorified Lord, that he may raise them up and save them. And indeed she exhorts them to contribute to the good of the People of God by freely uniting themselves to the Passion and death of Christ." Lumen Gentium 11.
