EXOD359 One is not to utter any word who sense is heresy (Heaven forbid), or some acknowledgment of idolatry (Heaven forbid). For if anyone acknowledges idol-worship, it is as though he denies heretically the entire Torah, since he denies the very fundamental principle. And we are duty-bound to be ready to give up our lives and our might over this; for in regard to all things that touch on the main principle of our faith, there is an obligation to accept death [if necessary] and not transgress.
