The body of Christ is present in substance; the soul and divinity are present by concomitancy (association). The soul and divinity are not present in substance.
The most holy Eucharist has indeed this in common with the rest of the sacraments, that it is a symbol of a sacred thing, and is a visible form of an invisible grace; but there is found in the Eucharist this excellent and peculiar thing, that the other sacraments have then first the power of sanctifying when one uses them, whereas in the Eucharist, before being used, there is the Author Himself of sanctity. For the apostles had not as yet received the Eucharist from the hand of the Lord, when nevertheless Himself affirmed with truth that to be His own body which He presented (to them). And this faith has ever been in the Church of God, that, immediately after the consecration, the veritable Body of our Lord, and His veritable Blood, together with His soul and divinity, are 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 the species of wine, and the blood under the species of bread, and the soul under both, by the force of that natural connexion and concomitancy whereby the parts of Christ our Lord, who hath now risen from the dead, to die no more, are united together; and the divinity, furthermore, on account of the admirable hypostatical union thereof with His body and soul. Wherefore it is most true, that as much is contained under either species as under both; for Christ whole and entire is under the species of bread, and under any part whatsoever of that species; likewise the whole (Christ) is under the species of wine, and under the parts thereof.
