I have no problem with that, since the Judeo Christian morality and values were the founding of this country. But what Jefferson was referring to is that amazingly enough (or not), all basic moral absolutes are essentially the same in all monotheist religions, and I include Hinduism since it is actually monotheistic. Even Buddhism, which is more a philosophy than an actual religion, espouses the same moral absolutes - did you know the Dalai Lama considers homosexuality unnatural and is against same sex marriage?
Even Islam, as much as I loathe it, has in principle, the same moral values. Leaving aside polygamy, but that is extant in the OT as well.
Bad Juju and Bad Zen.
