HOLY EUCHARIST
The Sacrament of the Holy Eucharist is the true Body and Blood of Jesus Christ, together with his soul and Divinity, under the appearances of bread and wine. This Sacrament completes the Sacraments of Christian Initiation, because those who have been raised to the dignity of the royal priesthood by Baptism, and configured more deeply to Christ by Confirmation, participate with the whole community in the Lord’s own sacrifice by means of the Eucharist.
The Eucharist is the heart and the summit of the Church’s life, for in it Christ associates his Church and all her members with his sacrifice of praise and thanksgiving offered once and for all on the cross to his Father; by the sacrifice he pours out the graces of salvation on his Body which is the Church. (C/f CCC 1407). It is important to note that, anyone who desires to receive Christ in the Eucharistic communion must be in the state of grace. Anyone aware of having sinned mortally must not receive communion without having received absolution in the Sacrament of Penance. (C/f CCC 1415).
Worthy of note here is that, the most venerable sacrament is the blessed Eucharist, in which Christ the Lord himself is contained, offered and received, and by which the Church continually lives and grows. The eucharistic Sacrifice, the memorial of the death and resurrection of the Lord, in which the Sacrifice of the cross is forever perpetuated, is the summit and the source of all worship and Christian life (Can. 897).
