The sacraments of the Catholic Church are, the Roman Catholic Church teaches, '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.'

Though not every individual has to receive every sacrament, the Church affirms that, for believers as a whole, the sacraments are necessary for salvation, as the modes of grace divinely instituted by Christ Himself. Likewise, as the sole dispenser of Christ's sacraments, the Catholic Church itself is spoken of as 'The universal sacrament of salvation' containing the individual seven sacraments. Through each of these sacraments, according to the Church, Christ bestows that sacrament's particular grace, such as incorporation into Christ and the Church, forgiveness of sins, or consecration for a particular service.

The Church teaches that the effect of a sacrament comes by the very fact of being administered, regardless of the personal holiness of the minister administering it. However, a recipient's own lack of proper disposition to receive the grace conveyed can block the effectiveness of the sacrament in that person. The sacraments presuppose faith and through their words and ritual elements, nourish, strengthen and express faith.

The Catechism of the Catholic Church lists the sacraments as follows: '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.'
