About this book
What does it mean to live as a foreigner at home—and as the soul within the world?
Diognetus, an educated outsider, wants clear answers about Christians. Why do they reject Greek gods and Jewish ceremonies? Who is their God, and why is their faith so new? In The Epistle to Diognetus, an unknown Christian writer replies with a calm argument that reads more like a speech than a quarrel.
The letter moves from criticism of idols and religious rites to a vivid portrait of ordinary believers. They share their neighbours’ cities, language and customs, yet understand their belonging differently. The writer then presents Christian teachings about God’s Word, patience and redemption, linking an account of divine love to a life of imitation.

In short
What if the best defence of a faith were simply a calm description of how its people live? The Epistle to Diognetus is a short letter from an unknown Christian writer to a man named Diognetus.
From the 15-minute summary · Key idea 1
Diognetus asks questions and gets a gentle reply
Diognetus wants to know what God the Christians trust, why they refuse the gods of the Greeks, why they do not keep the ways of the Jews, and why they love one another so much. He also asks why this new people has appeared only now.
The writer does not treat him as an enemy. He prays that he may speak well and that Diognetus may listen well. That gentleness runs through the whole letter and sets it apart from angrier defences of the same age.
