As for much of Rome's own (heresy by way of novel theological invention, one example being claims for their own office of 'papacy', etc.) they are often one and the same, bound up as that issue (of overweening 'papal authority') is, within cause and effect relationship.
That should suffice to answer the question.
Now, about that question which I posed to you --- tell us just what specific "heresy" the folks at 'Got Questions' are guilty of.
You never answered the question; and now you have switched you accusations of schismatic to heresy.
So it appears you did not know the difference between the two until just now.
