Is Judaism more like Christianity or Islam?

[anvi]

Islam, like other religious traditions, is very complex.  At least complex enough to make the phrase "strict adherence to the Qur'an" somewhat meaningless.  In Sunni Islam, there are four major schools of jurisprudence that have different interpretations of the Qur'an and Hadith and then legalist "disputants" in addition to those.  Shia has its own variety of interpretations of the Qur'an.  And Sufi Muslims of either stripe have far more symbolic and mystical interpetations than the jurors of either major tradition.  In this way, the juridical heritage of Islam much more closely resembles that of the Jewish tradition with its complex rabinnical interpretive history and modern divisions.  I think the other major feature that Judaism and Islam share is a far more stringent version of monotheism than Christianity with its triune theology.

For whom?  I know many, many people from Muslim families that hail from Karachi and Delhi and Jakara and Istanbul and South Africa who are pretty "progressive" and reform-minded.  It's important, it seems to me, not to paint two billion people with too broad strokes and it's important not to confuse what clerics might insist on from what practicing laypeople do and believe.  I mean, I get your point, but I'm just saying that these sorts of things are pretty hard to quantify in traditions that are so global and adhered to by people of very different kinds in very different circumstances.
