St. Gregory the Theologian ca. 329-389
For we on our part graciously welcomed the leaders who had been assigned to the separated portion on the grounds that their novel secession was prompted by piety with the object of helping the struggle of Orthodox doctrine, and we did not reject them as enemies but embraced them as brothers who for a short time had contested our paternal inheritance, though in a brotherly, not a malicious way. Though we did not welcome their opposition, we respected their zeal. Disagreement motivated by piety is superior to concord held together by sentiment. That is why we converted their withdrawal to our increment, dispelling their suspicions by an act of charity and reversing the usual order to such a degree that instead of grace following their election, election followed grace, and we accepted to this end the consecration by alien hands, anticipated to a degree by the Spirit. You for your part laid aside your misgivings based on the letter and sought reassurance in the spirit… (Oration 6.11)
