Eating human flesh (aka, as you define it, real presence) was the accusation made against them. They denied the eucharist is flesh idea and because of their denial, were martyred.
You completely twisted what happened. Here is the scenario:
1) Romans accused the saints of eating human flesh, and the romans were sickened by the thought. I am correct in this.
2) The christians denied that they were eating human flesh, as so far they were accused.
3) therefore, they were killed for it.
now you are claiming something like this:
1)the romans acused them of beleiving in the real presence of Christ in the Eucharist
2) the christians denied it
3) therefore, they were killed for it
The first explanation makes much more sense. why? first of all because according to every other church writing at the time, christians believed in the real presence. Do I have to pour out tons of writings of the early church fathers?? I will if you need me to. The whole early church believed. I will prove it to you, while you will come up with not even one early church father who did not believe.
secondly, you think they were killed because they believed in the real presence? re-read your source again. Be honest with yourself, for the sake of honesty! The romans were disgusted. why? because they heard about what we believed about the eucharist and then apprehended the saints, accusing them of eating human flesh. Put yourself into the minds of unbelieving romans. they werent theologians, they were angry that it was heard that we christians were eating the flesh and drinking the blood of someone.
I cant believe the dishonesty some people will go to to try to prove their points. You should be ashamed of yourself for twisting the truth as you are attempting to do. I am going to prove this to you and then you can be quiet.
