Mischaracterization of something that Christians have done for 2000 years going all the way back to what the Apostles received from Christ. It is about Christian practice, not about what heretical theological revolutionaries like or dislike.
You use the term "mischaracterization". Do you mean I am making a mistatement when I say transubstantiation is a reenactment of the crucifixtion of Christ? Read the RCC Catechism and notice that it is a redux of the sacrifice being effected anew for the supplicant. Explain.
OR, do you mean that I am mischaracterizing the fact that Christians have believed transubstantiation for 2000 years? If this were the case, you would have to be claiming that the apostles and all Christians understood the supper in terms of transubstantiation. History tells us that it took several hundred years for trans to get traction. Explain.
As far as, "...heretical theological revolutionaries..." go, if you mean the men like Paul, Augustine, Calvin who spoke against certain popular theological positions of their day, I respectfully disagree with your assessment
