The main reason Judaism is not a good religion to convert to is because a new convert would have to accept the Jewish teaching that Jesus of Nazareth was a conman and a charlatan.
It went into effect in AD100. It is part of rabbinic law.
That is indeed relatively recent . We find the Prophet Jonah cautioning against Jewish exclusivity, supposedly in the 8th Century B.C., but during the 'Persian' period we see Jews impressing a lot of non-Jews re the events that the Purim holidays celebrate, generating a lot new converts, so I had the impression it was only some Jewish sects that concerned themselves with trying to ban proselytism as a policy, and that it was mainly post-exile Babylonian Jews that obsess over genealogies and 'racial purity' laws. I assumed it was the general 'permanent' case by the 2nd Century B.C.
you assume all kinds of idiotic things PIC------in the navy I learned this little
limerick ' A S S U M E makes an ASS out of U and ME . I this case it
is more like -----U (you) Jews never
obsessed over genealogies or racial
purity (laws) It is my EDUCATED belief that the SEEKING OF CONVERTS
became outlawed in Judaism because this activity was a capital crime as declared by the various despots that invaded or ruled over jews. In fact CANON LAW---rendered the conversion of a Christian by a jew to Judaism a CAPITAL CRIME---
The Assyrians also outlawed it as do the muslims. The grain of truth to which
Pic desperately clings is that some of the prophets (like Ezra) distressed over the
frequent marriage by jews of "foreign women"----who brought their religion and
customs along with them-----this stuff was especially prevalent amongst jews living Elsewhere---whether by migration or exile. The big time "lesson" was
JEZEBEL. Ezra's approach was controversial back then and actually---interestingly enough----remains a bone of contention between some jewish groups that I will not mention. I am intimately involved with someone from that group
