Is Judaism more like Christianity or Islam?

[Scam of God]

Which of the two 'spin-off' religions retains more of the essential character of the Jewish religion? I've always thought that Islam held more in common, insofar as both religions place a much higher emphasis on asceticism and personal purity (rather than personal piety) than the more liturgical Christianity, but I don't really know enough about Judaism and Islam to say.

I've always been of the opinion that Judaism : Islam :: Christianity : Mormonism; that is to say, I've always thought that Islam is basically Judaism extrapolated for an Arabic audience, much as Mormonism was an attempt to 'Americanize' Christianity. In that sense, they'd be essentially the same faith. Is that at all accurate?

(though despite this Christianity is the true religion while Mormonism is an abomination of lies.)

No, Christianity is pretty much a lie that the weak-willed tell themselves to get to sleep at night.

EDIT: Actually, Christianity is probably slightly more ridiculous than Islam. The very ethical foundation of Christianity is pathetic; at least Islam encourages a warrior mentality.
