Letter 6015: Gregory to John, Bishop of Constantinople. As the pravity of heretics is to be repressed by the zeal of a right faith, so the integrity of a true confession is to be embraced. For, if one who declares himself sound in the faith is scorned, the faith of all is brought into doubt, and fatal errors are generated from inconsiderate strictness.

Gregory to John, Bishop of Constantinople.

Just as the corruption of heretics must be checked by zeal for the true faith, so the integrity of a genuine confession of faith must be embraced. If someone who declares himself sound in the faith is spurned, the faith of everyone is called into doubt, and dangerous errors spring from thoughtless severity. The result is that not only are wandering sheep not brought back to the Lord's fold, but even those already inside are left exposed to the teeth of wolves. Let us consider this carefully, dear brother, and not allow anyone who truly professes the Catholic faith to be harassed under the pretext of heresy -- nor, God forbid, allow heresy to grow stronger under the guise of correcting it.

I have been greatly puzzled, then, as to why the judges you appointed in the case of John, priest of the church of Chalcedon, chose to believe rumor over truth and refused to accept his clear profession of faith. This is especially troubling given that his accusers, when asked to explain the Marcionist heresy they charged him with, openly admitted they did not know what it was. From this it is plain that they were not motivated by concern for God or justice but simply wished to harm him out of personal spite.

After holding a council, as the record of proceedings shows, and thoroughly examining everything necessary -- since we have been unable to find the aforementioned priest guilty of any wrong belief, and since the statement of faith he submitted to your appointed judges is entirely consistent with orthodox truth -- we therefore reject the sentence of those judges and, by the revealing grace of Christ our God and Redeemer, declare him by our definitive judgment to be Catholic and free from all charge of heresy.
