Epistle to Diognetus

The Epistle of Mathetes to Diognetus (Greek: Πρὸς Διόγνητον Ἐπιστολή) is an example of Christian apologetics, writings defending Christianity against the charges of its critics. The Greek writer and recipient are not otherwise known. Estimates of dating based on the language and other textual evidence have ranged from AD 130 (which would make it one of the earliest examples of apologetic literature), to the general era of Melito of Sardis, Athenagoras of Athens, and Tatian.
