many and such great Churches should have gone astray into a unity of
faith?
St. Athanasius, Letter on the Councils of Rimini and Seleucia 5 (361-
362 AD)
Without prefixing Consulate, month, and day, (the Fathers) wrote
concerning Easter, It seemed good as follows, for it did then seem good
that there should be a general compliance; but about the faith they wrote
not, It seemed good, but, thus believes the Catholic Church; and
thereupon they confessed how they believed, in order to show that their
own sentiments were not novel, but Apostolic; and what they wrote down
was no discovery of theirs, but is the same as was taught by the Apostles.
St. Athanasius, Synodal Letter to the Bishops of Africa 2 (inter 368-
372 AD)
But the word of the Lord which came through the Ecumenical Council at
Nicaea remains forever.
St. Ambrose of Milan, Letter to the Emperor Valentinian II 21, 14
(386 AD)
This (denial of the divinity of Christ) was written in the Council of
Rimini, and I am right when I shiver at the thought of that Council. I follow
the teaching of the Council of Nicaea, from which neither death nor the
sword shall ever be able to separate me.

Leo I 98, 1 (451 AD)
