When hard pressed in the struggle against heretics, people felt that they could turn with confidence to the Pope…"

And the Popes in the first millennium professed the same Orthodox Faith we profess to this day, and many of them are Orthodox Saints.

Heresies reached, and most often sprang out of Constantinople, with the Imperial Patriarch as their chief architect. Satan managed to deceive the second only to the Pope, but the Popes never wavered (save for one possibly). We Orthodox have a lot to thank the Bishops of Rome.

For, such greats as +John Chrysostom and +Maximos the Confessor found refuge from heretical Patriarchs of Constantinople, and warm and brotherly welcome and encouragement among the Popes of Rome.

"And the Popes in the first millennium professed the same Orthodox Faith we profess to this day, and many of them are Orthodox Saints."

Here's a link to a list of them. I don't know if it is complete but it looks it. Its from a Roman source so the "spin" may be a bit off what we would say.
