.We are not permitted to study cults, other religions, other philosophies-that is a fact derived from Torah
‘make no mention of the names of other gods; they shall not be heard on your lips.’Vayikra 23.13
‘Most cults never heard of the Torah’- we don’t know that for sure, but the cults, all cults are still forbidden.
True beliefs exclude cults.
Judaism is the only true belief. Torah emes.
