In Henry Chadwick’s history The Early Church there are some absolute gems which I’ll post for your reflection, edification and application.
Chadwick writes that in the 2nd century AD a ‘vivid and cruel portrait [of the church] was painted by the pagan satirist Lucian of Samosata (c.170)’ and then he says this,
Lucian had a low opinion of the human race, and treated Christianity as merely additional evidence of human absurdity and folly. But he knew that the Christians were unbelievably generous with their money and preferred to be open-handed rather than inquire too closely into the recipients. (p57)
Emphasis mine. Could our opponents possibly say that of the church today? Unbelievably generous and open handed?
