what’s ironic is anyone who denies the Real Presence in the Eucharist would not fellowship or worship with Tertullian, Origen or Clement and they would have considered such people heretics, outside the Faith.

Either you deny His resurrection and transfiguration and put Him back into His mortal flesh or …….?
