Gregory to Olympius.

Even gray hairs have something to learn, and old age, it seems, cannot always be trusted for wisdom. I knew better than anyone the thoughts and the heresy of the Apollinarians, and yet I allowed myself to be persuaded into a course of action I now regret.

But confession is the beginning of correction. And now, armed with the wisdom that bitter experience provides, I ask your help in repairing the damage. Support the cause of orthodoxy, as you have always done, and do not let the Apollinarian error find shelter in our province.
