Overview: The Sacraments
The life of the church revolves around the sacraments especially the Eucharist. There are three sacraments of initiation into the Christ-life: Baptism, Confirmation and Eucharist. There are two sacraments that are channels of God’s forgiveness and healing at certain times in life: Reconciliation (Penance or Confession) and the Anointing of the Sick. There are two sacraments that mark a significant change in one’s life in response to God’s call: Ordination (Holy Orders) and Matrimony.
All the sacraments are signs and channels of God’s grace, making God’s love present to believers.
The sacraments bear fruit both in the person and in the church. The believer deepens their life in Christ, and their relationship to God. The church deepens their desire to ‘love one another’ as Christ commanded, and is energized for Christ’s mission, and as witnesses to his gospel.
The Church celebrates the mystery of her Lord "until he comes," when God will be "everything to everyone." In the sacraments of Christ the Church already receives the guarantee of her inheritance and even now shares in everlasting life, while "awaiting our blessed hope, the appearing of the glory of our great God and Saviour Christ Jesus."
