Given that sin destroys our relationship with God and undermines our relationship with other human beings, “reconciliation” designates that precise effect of Christ’s redemption of the human race that restores our relationship with God and our human fellowship. Christ breaks down the barriers that sin raises between us and God, and within the human community. Our conversion from sin and reception of divine mercy are continually renewed by confession. Serious sin separates us from the body of the church, and sacramental penance reconciles us with God and the community of his people. This sacrament is also referred to as the sacrament of penance or confession.
The Eucharist completes Christian initiation. Through this sacrament of initiation we participate with the whole community of believers in the Lord’s own sacrifice. The Eucharist (from the Greek word eucharistia meaning “thanksgiving”) is the sacrament of the body and blood of Christ in which he is present under the forms of bread and wine offering himself in the sacrifice of the Mass and giving himself as spiritual food to the faithful.
At the Last Supper, the Lord instituted the eucharistic sacrifice of his body and blood. He did this in order to perpetuate the sacrifice of the cross throughout the ages until he should come again, and so to entrust to the church a memorial of his death and resurrection. The Eucharist is the source and summit of the Christian life.
Confirmation brings to completion the grace received through baptism. By this sacrament the baptized are more perfectly bound to the church and are enriched by the strength of the Holy Spirit. This gift conforms believers more fully to Christ and strengthens them to bear witness to Christ for the building up of his body in faith and love.
