Sacraments of the Christian initiation constitute on one hand the origin of the Christian life and on the other hand the fullness of this life. It happens so, because Eucharist as the third sacrament of the Christian initiation is a source and summit of the Christian life. These sacraments are: the participation in the fullness of the life received in the baptism; the life of Holy Spirit who is present in mainstreams and in the most important moments of our life (confirmation); the thanksgiving and the sacrifice given to the Father in heaven in the Eucharistic activity of the Lord and in His unity with the Holy Spirit. Each of this sacraments is the Passover of the Lord, the mystery of His death and resurrection completed by the Holy Spirit. The target of these sacraments is the unification of man with God.
