Why then do we think that this [hoping for change in the pagan faith] is sufficient and do not observe how the kindness of Christians to strangers, their care for the burial of their dead, and the sobriety of their lifestyle has done the most to advance their cause?…

For it is disgraceful when no Jew is a beggar and the impious Galileans [Christians] support our poor in addition to their own; everyone is able to see that our coreligionists are in want of aid from us.

Julian the Apostate, Roman Emperor, in a letter to Arsacius the priest, AD 360

Those pesky Christians…being kind to strangers, taking care of the pagan poor, their high regard for life. Sounds like a lot of work. Couldn’t they have found some doctrine to fight over or some network to boycott?
