Which part, the divine substance or the physical properties of the specific species?
Which part????
Jesus said that in order to have eternal life, you had to eat His body and blood. Catholics are the ones who demand that that passage be taken literally.
If that's the case, then the host MUST be literally be transformed into the literal flesh and blood of Jesus and literally be eaten.
Are you now telling us that that is NOT the case?
According to the RCC you cant have it both ways. If you claim that the physical properties of the bread and wine remain you are anathema.
CANON II. If any one says, that, in the sacred and holy sacrament of the Eucharist, the substance of the bread and wine remains conjointly with the body and blood of our Lord Jesus Christ, and denies that wonderful and singular conversion of the whole substance of the bread into the Body, and of the whole substance of the wine into the Blood the species Only of the bread and wine remaining which conversion indeed the Catholic Church most aptly calls Transubstantiation; let him be anathema. (Council of Trent, 13th session) The form of this sacrament are the words of the Saviour with which he effected this sacrament. A priest speaking in the person of Christ effects this sacrament. For, in virtue of those words, the substance of bread is changed into the body of Christ and the substance of wine into his blood. In such wise, however, that the whole Christ is contained both under the form of bread and under the form of wine, under any part of the consecrated host as well as after division of the consecrated wine, there is the whole Christ. (Council of Florence, 8th Session)
