Was Jesus the Messiah circumcised ?
I'd answer by saying that we need to prove he even existed before going to question his winkie.
Many start off with the premise that he existed.
He didn't write any books of the Bible (that was bunged together by some geezers who did a bit of an 'eenie meenie miny mo' for this).
There is absolutely no evidence of his existing outside of the Bible.
I know this character was supposed to be walking mysteriously and shizz, but come on.
The nearest are vagaries that can be crowbarred into the fiction.
Yep! First, prove this geezer existed outside of the Bible. I'll give a hint. No one can. It's all made up!
