It was brought up in another thread that Paul got his Roman citizenship by serving as a soldier for at least 20 years. This was the only way a non-italian non-Roman born could do it.
I remember an illustration - in one of the big books, like "things in which it is impossible for God to lie" or "life everlasting" where Saul of Tarsus is pictured holding the robes of those who are stoning christians to death.
He is dressed as a Roman soldier with a metal breast plate. Anybody have a scan of this?
I am also convinced that his illustration of spiritual armor is based on his training as a Roman soldier. That is where he would have been trained to make and mend tents of course.
