<br><font size=2 face="sans-serif">i had the impression, i'm
not sure where i heard it, that a major purpose of instituting
the 19th bracha was to get out of shul, those who outwardly
looked jewish , but held alien beliefs, such as praying
to the trinity. someone over sukkot took great offense
to this idea, that there were jews who became xtians and were praying on
shul to other than the RBSO. it seems that the rambam
talks about the bracha as a warning to jews
to avoid </font>
<br><font size=2 face="sans-serif">heretical movements , rather than a
community purification method,</font>
<br>
<br><font size=2 face="sans-serif">maybe i am conflating a few
ideas, but the question is 1] was there initially a
problem with 'hebrew xtians' that this bracha caused to leave the
shuls</font>
<br><font size=2 face="sans-serif">2] was the bracha more a
curse and a warning , rather than a method to separate these sects into
separate communities 3] are there numbers as to the percent
of prushim [pharisees] versus tzdukim, baitusim,
xtians, etc and did they have their own institutions
?</font>

<br><font size=2 face="sans-serif">[ maybe i am conflating the issue
the fast of Ezra, which many have pointed to , as commemorating the effort
to separate out the early xtian community by paul]....<br>
