I am shocked at the notion of digging up popes for trial, and the notion that anyone who did this was still pope and capable of speaking ex cathedra makes me laugh at the possibility of union between the Orthodox and Rome.
Rome should have distanced itself from this years ago.
What more are they supposed to do to distance themselves. The pope who led the trial was promptly imprisoned and killed. The next pope annuled the verdict only months later. Then a year later the pope forbade any future trials of dead people.
Also the dead pope accused at trial really had invited the Franks to invade Italy.
