If you haven’t yet stopped by Libby Anne’s blog, you should at the very least check out this post about Kirk Cameron and Doug Phillips.
Phillips teaches that a woman is never to be out from under male authority no matter her age or marital condition, and that being under male authority includes complete submission and obedience, because God speaks to women through their male authorities. This is nothing short of slavery.
Christians all too often criticize mainstream Muslims for failing to police the more radical and barbaric of their sects, but turn a blind eye to oppression and medieval morality in their own ranks.
