Your choice. Last chance.
You’d have to handle disagreement about just what everybody, everywhere... believed.
Putting that aside, you had major disagreements and heresy going on. Those wouldn’t fit your method. To take one major example, who Christ was/is. Would you accept the decrees of the First Council of Nicaea? Arius or Athanasius? Would the dogma Arianism be ok? You end up violating your criteria one way or the other.
The Church accepts the Council.
