But you asked a theological question. So you have to approach it methodologically. Basically, put your feet into muslim shoes. If you are unable, then you will of course not understand or agree.
No, I made a point about factual history, not theology. I don't really care whether the issue has theological importance or not because I'm not trying to critique Islam the religion, but just have an interest in history.
If I put myself in a Muslim's shoes I would be basing my beliefs on different axiomatic assumptions which is why the two approaches don't mix. We both start with the unchallenged assumption that the other's approach is fundamentally wrong.
From a historical perspective though:
Imo it is a fair assumption that Muhammad understood who the Sabians were.
The evidence shows that later exegetes did not know.
Therefore we have some knowledge that has been lost (a point which is supported by exegetes not understanding other parts of the Quran, and the growth of hadith/sirah literature that helped explain these passages).
I am not gonna respond to your rhetorical "hoops" and other cross fence type of discussion.
You aren't going to respond to my simple request that you clarify what you think I said, in the context I said it so we can see if you are barking up the wrong tree or not?
And that such a request is a "cross fence rhetorical hoop"
Kind of sums up your approach perfectly.
Well done.
