I think they were called clerks for a long time after that too. John Newton, the writer of Amazing Grace, had it written on his gravestone, in Olne, England. "John Newton, clerk. Once an infidel and libertine." I believe he saw, and understood the simplicity of the gospel. I would not classify him as one who was ever learning, but never able to come to the knowledge of the truth. He came to the truth, or maybe I should say, the truth came to him.
Thats interesting..thanks for the factoid..
