The sacramentality of the Church
16. The Second Vatican Council recalled that "all the sacraments, and indeed all ecclesiastical ministries and works of the apostolate, are bound up with the Eucharist and are directed towards it. For in the most blessed Eucharist is contained the entire spiritual wealth of the Church, namely Christ himself our Pasch and our living bread, who gives life to humanity through his flesh – that flesh which is given life and gives life by the Holy Spirit. Thus men and women are invited and led to offer themselves, their works and all creation in union with Christ." (41) This close relationship of the Eucharist with the other sacraments and the Christian life can be most fully understood when we contemplate the mystery of the Church herself as a sacrament. (42) The Council in this regard stated that "the Church, in Christ, is a sacrament – a sign and instrument – of communion with God and of the unity of the entire human race." (43) To quote Saint Cyprian, as "a people made one by the unity of the Father, the Son and the Holy Spirit," (44) she is the sacrament of trinitarian communion.
The fact that the Church is the "universal sacrament of salvation" (45) shows how the sacramental economy ultimately determines the way that Christ, the one Saviour, through the Spirit, reaches our lives in all their particularity. The Church receives and at the same time expresses what she herself is in the seven sacraments, thanks to which God's grace concretely influences the lives of the faithful, so that their whole existence, redeemed by Christ, can become an act of worship pleasing to God. From this perspective, I would like here to draw attention to some elements brought up by the Synod Fathers which may help us to grasp the relationship of each of the sacraments to the eucharistic mystery.
