As sacrifice, the Eucharist is also offered in reparation for the sins of the living and the dead and to obtain spiritual or temporal benefits from God.
Anyone who desires to receive Christ in Eucharistic communion must be in a state of grace. Anyone aware of having sinned mortally must not receive communion without having received absolution in the sacrament of penance.
Communion with the Body and Blood of Christ increases the communicantís union with the Lord, forgives his venial sins, and preserves him from grave sins. Since receiving this sacrament strengthens the bonds of charity between the communicant and Christ, it also reinforces the unity of the Church as the Mystical Body of Christ.
The Church warmly recommends that the faithful receive Holy Communion each time they participate in the celebration of the Eucharist; she obliges them to do so at least once a year.
Q: What is Holy Communion?
A: Holy Communion is the receiving of the body and blood of Christ.
Q: Is it not beneath the dignity of Our Lord to enter our bodies under the appearance of ordinary food?
A: It is not beneath the dignity of Our Lord to enter our bodies under the appearance of ordinary food any more than it was beneath His dignity to enter the body of His Blessed Mother and remain there as an ordinary child for nine months. Christ's dignity, being infinite, can never be diminished by any act on His own or on our part.
Q: What is necessary to make a good Communion?
A: To make a good Communion it is necessary to be in the state of sanctifying grace and to fast according to the laws of the Church.
Q: Does he who receives Communion in mortal sin receive the body and blood of Christ?
A: He who receives Communion in mortal sin receives the body and blood of Christ, but does not receive His grace, and commits a great sacrilege.
Q: Is it enough to be free from mortal sin to receive plentifully the graces of Holy Communion?
A: To receive plentifully the graces of Holy Communion it is not enough to be free from mortal sin, but we should be free from all affection to venial sin, and should make acts of lively faith, of firm hope, and ardent love.
