The Ecclesiastical History, Dialogues, and Letters of Theodoret.: Of the ambassage of Chrysostom to Gainas.

Chapter XXXIII.—Of the ambassage of Chrysostom to Gainas.

Then when every one else was passed over because of the universal panic, this great chief was persuaded to undertake the ambassage. He took no heed of the dispute which has been related, nor of the ill feeling which it had engendered, and readily set out for Thrace. No sooner did Gainas hear of the arrival of the envoy than he bethought him of the bold utterance which he had made on behalf of true religion. He came eagerly from a great distance to meet him, placed his right hand upon his eyes, and brought his children to his saintly knees. So is it the nature of goodness to put even those who are most opposed to it to the blush and vanquish them. But envy could not endure the bright rays of his philosophy. It put in practice its wonted wiles and deprived of his eloquence and his wisdom the imperial city—aye indeed the whole world. 923

Footnotes

It is not clear where the mission of Chrysostom to Gainas should be placed. Gainas attacked the capital by sea and by land, but his Goths were massacred in their own church, and he was repulsed. He was finally defeated and slain in Jan. 401.
