Okay, well then why do you think Saul did it?
Because that was common practice at the time. Many people in the Bible who lived in different cultures took two different names: one Hebrew name and one foreign name. Prominent examples include:
Esther (Esther 2:7) whose Persian name was Hadassah.
Daniel, Hananiah, Mishael, and Azariah, (Daniel 1:7) who were given the Babylonian names Belteshazzar, Shadrach, Meshach, and Abednego respectively.
The Apostle Peter (Greek: Petros) is often referred to alternately in the New Testament as Cephas (Hebrew), both of which simply mean Rock. (for instance, see Gal 1:18-2:14)
Those examples are simply taken directly from the Bible. I was not using any sort of website to look up anything, they are just from memory. I am certain that more exist, however that ought to be enough to dispel your notion that people did not change their names - they quite frequently went under two names depending on the cultural context, when there was a mingling of cultures, as is the situation with Paul.
Perhaps you just desire that to be the case so you can have a “flaw” in Christianity and their beliefs.
What makes you think I am looking for a flaw? Personallly I don’t see how this is a flaw in Christianity. I am simply claiming that you don’t know your Bible well enough to bother defending it.
He renamed from Saul to Paul. Anyone not trying to read more into the Bible then is written there will see this as the case. I think you’re just over thinking the situation.
Actually I think you’re reading something that is clearly not there. Show me where it is written that he renamed. I have cited several verses from the Bible, you have yet to cite one. The only time you have attempted to cite any specific verses to me, it was in the other thread where it was clear that the passage meant the opposite of what you were trying to make it say. Somehow this gives me little confidence you will be able to prove your point. All I have from you are assertions. If you say it often enough, it will not magically appear when you open your Bible.
He changed his identity when his religion changed, to reflect that his name changed as well.
Again, SHOW ME WHERE. You can claim this as often as you like, but you have yet to back this up. I have given you several specific verses that seem to counter your claim, including when he is called Saul AFTER becoming a Christian, but you have not given one.
