The Mass, known more fully as the Most Holy Sacrifice of the Mass is the central liturgical ritual in the Catholic Church where the bread and wine are consecrated and become the body and blood of Christ. As defined by the Church at the Council of Trent, in the Mass, “The same Christ who offered himself once in a bloody manner on the altar of the cross, is present and offered in an unbloody manner. ” The Church describes the Holy Mass as “the source and summit of the Christian life”. It teaches that through consecration by an ordained priest the bread and wine become the sacrificial body, blood, soul, and divinity of Christ as the sacrifice on Calvary made truly present once again on the altar. The Catholic Church permits only baptised members in the state of grace (Catholics who have recently confessed all mortal sins) to receive Christ in the Eucharist.
