Just not so ..there was no real consensus on the Lords supper and men were free to believe yes or no ..a close reading of the church fathers show some thought Christ was spiritually present not the platonic view of a physical presence ..it was not doctrine that was required until the Lateran council
So the question is only the "real presence" if one does not believe that the spiritual is real
No. The Real Presence was a key part of the Christian Faith from Scripture onwards as far back as we have records, contiguously.
The early martyrs were martyred for this belief and others. I would not take it lightly.
I'm sorry, but this statement shows an almost total lack of the vocabulary, philosophy, and what the debates between the Platonic and Aristotelean spheres was about; along with an erroneous conflation concerning the Real Presence.
Study up on it quite a bit more and perhaps it can be discussed here.
