The eyes of faith enable the believer to recognize the ineffable depths of the mystery that is the Holy Eucharist. Lord’s Supper, holy and divine Liturgy, Holy Communion, and Holy Mass.

They are thereby joined together as members of Christ’s mystical Body, sharing the one life of the Spirit.
In the great sacrament of the altar, they are joined to Christ Jesus and to one another. This sacrament is also to be a remedy to free us from our daily defects and to keep us from mortal sin. As Catholics, we fully participate in the celebration of the Eucharist when we receive Holy Communion. We are encouraged to receive Communion devoutly and frequently.
