"For I received from the Lord what I also handed on to you: that the Lord Jesus, on the night he was handed over, took bread, and after he had given thanks, broke it, saying "This is my body that is for you. Do this in remembrance of me." (1 Corinthians 11:23-24)
The Holy Eucharist is the most important of the seven sacraments because in the Eucharist we receive the very body and blood, soul and divinity of Jesus Christ.
When we come to the Eucharist, we participate in both Jesus' Last Supper and his Sacrifice on the Cross. Through our prayers and rituals, we hear Jesus' words in the Scriptures, offer our own lives to God, and receive Jesus' body in Communion.
Communion is an intimate encounter with Jesus Christ, in which we sacramentally receive Christ into our bodies, that we may become more like him.
