876: The Excellence of the Most Holy Eucharist Over the Other Sacraments
This, indeed, the most Holy Eucharist has in common with the other sacraments, that it is a “symbol of a sacred thing and a visible form of an invisible grace”; but this excellent and peculiar thing is found in it, that the other sacraments first have the power of sanctifying, when one uses them, but in the Eucharist there is the Author of sanctity Himself before it is used [can. 4]. For the apostles had not yet received the Eucharist from the hand of the Lord [Matt. 26:26; Mark 14:22] when He Himself truly said that what He was offering was His body; and this belief has always been in the Church of God, that immediately after the consecration the true body of our Lord and His true blood together with His soul and divinity exist under the species of bread and wine; but the body indeed under the species of bread, and the blood under the species of wine by the force of the words, but the body itself under both by force of that natural connection and concomitance by which the parts of Christ the Lord, “who hath now risen from the dead to die no more” [Rom. 6:9], are mutually united, the divinity also because of that admirable hypostatic union [can. I and 3] with His body and soul. Therefore, it is very true that as much is contained under either species as under both. For Christ whole and entire exists under the species of bread and under any part whatsoever of that species, likewise the whole (Christ) is present under the species of wine and under its parts [can. 3].
