So I'm currently writing a story set in an Arabian-influenced medieval world. This society worships a mother goddess, and I was wondering if a matriarchal religion is culturally consistent for a culture that is also patriarchal in its family and political structures (and also pride themselves in having a strong military class). 

I tried to research empires in history that worshipped a central female goddess, but there doesn't seem to be a lot of information in regard to these societies' power structures, since many of them predate the popularization of Abrahamic religions.  

However, from what I've gathered I think men and women in these societies still followed heteronormative roles.

Can anyone give their two cents in this subject, or point me to a few resources that could give me more information?
