I have no problem with Clement, but the writings attributed to him establishing Primacy were proved to be forgeries.
(By Roman scholars)
Pope Gregory the Great rejected the title of “universal”....
Preminence is not a problem with most Orthodox Christians. The Pope was the “first among equals”, or “chairman of the board” (my analogy)....
One day, maybe he will resume that role, and speed reunion....
The Orthodox already have a”chairman of the board,” and look how they treat him.
