The Liturgy

In the Church's liturgy the divine blessing is fully revealed and communicated. the Father is acknowledged and adored as the source and the end of all the blessings of creation and salvation. In his Word who became incarnate, died, and rose for us, he fills us with his blessings. Through his Word, he pours into our hearts the Gift that contains all gifts, the Holy Spirit.

The 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 covena nt.

The Sacraments of Initiation

The Compendium of the  Catechism of the Catholic Church states: "Christian  initiation is accomplished by  means of the  sacraments which establish the foundations of Christian life. The faithful born anew by Baptism are strengthened by  Confirmation and are then nourished by the Eucharist."
