St. Optatus, 1500 years prior, apparently knew the answer:
St. Optatus writes to Parmenian:
But you allege that you too have some sort of a party in the City of Rome. It is a branch of your error growing out of a lie, not from the root of truth. In a word, were Macrobius to be asked where he sits in the City, will he be able to say on Peter’s Cathedra? I doubt whether he has even set eyes upon it, and schismatic that he is, he has not drawn nigh to Peter’s Shrine…. Behold, in Rome are the Shrines of the two Apostles *. Will you tell me whether he * has been able to approach them, or has offered Sacrifice in those places, where as is certain are these Shrines of the Saints.
And:
ou cannot then deny that you do know that upon Peter first in the City of Rome was bestowed the Episcopal Cathedra, on which sat Peter, the Head of all the Apostles … that, in this one Cathedra, unity should be preserved by all [in qua unica Cathedra unitas ab omnibus servaretur], lest the other Apostles might claim each for himself separate Cathedras, so that he who should set up a second Cathedra against the unique Cathedra would already be a schismatic and a sinner. Well then, on the one Cathedra, which is the first of the Endowments, Peter was the first to sit.
o, of the above-mentioned Endowments, the Cathedra is, as we have said, the first, which we have proved to be ours, through Peter, and which draws to itself the ANGEL — unless, perchance, you claim him for yourselves, and have him shut up somewhere or other.30**
1500 years ago I would probably have sought unity with Rome too.
This was before Rome started teaching error. So it was right to seek unity with Rome.
