The late great theologian, pastor, and teacher Harry A. Ironside once used the following illustration in one of his sermons:
When Pliny was governor of Bithynia, he wrote a most interesting letter to the Roman Emperor Trajan, asking why Christians were being exterminated, and added: “I have been trying to get all the information I could regarding them. I have even hired spies to profess to be Christians and become baptized in order that they might get into the Christian services without suspicion.
“Contrary to what I had supposed, I find that the Christians meet at dead of night or at early morn, that they sing a hymn to Christ as God, that they read from their own sacred writings and partake of a very simple meal consisting of bread and wine and water (the water added to the wine to dilute it in order that there might be enough for all).
“This is all that I can find out, except that they exhort each other to be subject to the government and to pray for all men.”
