The correction is it is a mystery. Christ did not detail how the bread is His body. He only said that, “this [bread] is my body”. Certainly, we see, feel, touch, taste bread and wine, but we know that it is not mere bread and wine. It is His body and His blood, given and shed for the remission of sin.=Nita;9108108]We’ve been on Eucharist threads together before, so I know how close your beliefs are to Catholic teaching. I don’t want to sidetrack this thread, but perhaps my question/s can be answered quickly.
Using “substance” in it’s philosophical sense, do you hold that the original bread and wine have the substance of bread and wine? - and thus that a change occurs whereby those substances (of bread and wine) are transformed into the substances of flesh and blood?
If someone were to preach that both substances were present in the Eucharist - those of bread/wine and Christ’s body/blood - would you accept that position as true? If not, how would you correct it?
As you know, Lutherans don’t use philosphical language regarding the Eucharist, but if you put me in the position of choosing transub or consub, I would choose transub, as it more closely reflects Christ’s own words.
I’ll reference the Lutheran-Catholic dialogue on the Eucharist, which speaks directly to the issue: prounione.urbe.it/dia-int/l-rc/doc/e_l-rc_eucharist.html
Eucharistic Presence
JonCatholic and Lutheran Christians together confess the real and true presence of the Lord in the Eucharist. There are differences, however, in theological statements on the mode and therefore duration of the real presence.
In order to confess the reality of the eucharistic presence without reserve the Catholic Church teaches that "Christ whole and entire"34 becomes present through the transformation of the whole substance of the bread and the wine into the substance of the body and blood of Christ while the empirically accessible appearances of bread and wine (accidentia) continue to exist unchanged. This “wonderful and singular change” is “most aptly” called transsubstantiation by the Catholic Church.35 This terminology has widely been considered by Lutherans as an attempt rationalistically to explain the mystery of Christ’s presence in the sacrament; further, many suppose also that in this approach the present Lord is not seen as a person and naturalistic misunderstandings become easy.
The Lutherans have given expression to the reality of the Eucharistic presence by speaking of presence of Christ’s body and blood in, with and under bread and wine�but not of transsubstantiation. Here they see real analogy to the Lord’s incarnation: as God and man become one in Jesus Christ, Christ’s body and blood, on the one hand, and the bread and wine, on the other, give rise to a sacramental unity. Catholics, in turn, find that this does not do sufficient justice to this very unity and to the force of Christ’s word “This is my body”.
The ecumenical discussion has shown that these two positions must no longer be regarded as opposed in a way that leads to separation. The Lutheran tradition agrees with the Catholic tradition that the consecrated elements do not simply remain bread and wine but by the power of the creative Word are bestowed as the body and blood of Christ. In this sense it also could occasionally speak, as does the Greek tradition of a “change”.36 The concept of transsubstantiation for its part is intended as a confession and preservation of the mystery character of the Eucharistic presence; it is not intended as an explanation of how this change occurs37 (see the appendices on “Real Presence” and “Christ’s Presence in the Eucharist”).
