Can it be that she was an adulteress to the law of Moses by following Jesus?
Even worse... she made Him King and high Priest...

The passage about Jesus forgiving her is not just to show how a nice guy Jesus was/is.
There are only 3 persons that can forgive a woman adultary.
Her husband. Her father. Her oldest son.
We all know Jesus didn't marry and didn't have children.
He was her adopted son. (bloodlien of David and Nathan etc)
When a woman was caught in adulatry she coul dbe stoned to death or forgiven. But even wheb forgiven all her offspring born after the adultary would be bastards. Meaning nobody born after her adultary could be the new pillar.
Meaning nobody could annoint new priests and kings. Not sure but if she hadn't chidren before the event it simply means it's impossible the messiah the Jews are waiting for can ever exist.
Only kings can sit on David's throne. But if there is nobody that can annoit the king.....
OTOH I'm sure the hundreds of Rabbis that teach a future Messiah didn't overlook what I wrote in this post. So I could be very wrong...
