**The Holy Eucharist is the Whole Christ
by Fr. John A. Hardon, S.J.
The most fundamental question to ask about the Blessed Sacrament is, “Who is the Holy Eucharist?” And the correct answer is: The Holy Eucharist is Jesus Christ.
There is more behind this answer than many Catholics realize. When the Council of Trent in the sixteenth century defined the meaning of the Eucharist, it declared that “the Body and Blood, together with the Soul and Divinity of our Lord Jesus Christ, and therefore the whole Christ, is truly, really and substantially contained in the sacrament of the Holy Eucharist.”
Shortly after Trent, Pope St. Pius V authorized the publication of the Roman Catechism which built on the Council of Trent and explained its teachings for the pastors of the Church.
Regarding the Real Presence, the pastors were told to explain that “in this sacrament is contained not only the true Body of Christ-and that means everything that goes to make up a true body, such as bones, nerves, and so on-but also Christ whole and entire.” Consequently the Eucharist contains Jesus Christ in the fullness of his divinity and the completeness of his humanity.
Jesus is therefore in the Blessed Sacrament “whole and entire: the Soul, the Body and Blood of Christ, with all their component parts. In heaven a complete human nature is united to the divine nature in one. . . person. It is a denial of the faith to suppose that in this sacrament there is anything less.”**
