“From the start it has been your custom to treat all Christians with unfailing kindness, and to send contributions to many churches in every city, sometimes alleviating the distress of those in need, sometimes providing for your brothers in the mines.”
Dionysius of Corinth (c. 170) excerpt from letter to the Church in Rome as quoted by Eusebius in Ecclesiastical History, 4.23.6 (1965)
