The Letter To Diognetus Alternate title: The Epistle To Diognetus c. 100-150 C.E. The Epistle to Diognetus is a well-crafted argument extolling the virtues of Christianity over paganism. It is difficult to determine the date of the letter, for it was never referred to in any known ancient writings, but it obviously dates from a period when Christianity was still regarded as a mystery religion.
