The two main sacraments, baptism and the Eucharist, are the spiritual pillars of the Church.  They are not simply instruments by which the Church exercises its ministry.  They are not just means by which we become and remain members of the Church but belong to the essence of the Church.  Without these sacraments there is no Church.  The Church is the body of Christ fashioned by baptism and the Eucharist.  When people are baptised in the Name of the Father and the Son and the Holy Spirit, and when they gather around the table of Christ and receive his Body and Blood, they become the people of God, called the Church.
