Checking in on our new beliefs here, we see +2 culture, a waste, and +10% growth, a reasonable enough bonus though significantly less so at this stage of the game. It is interesting to see Fertility Rites go to a religion whose leadership is comprised almost exclusively of women and gay men (again, per Wikipedia). I say this not as any kind of value judgment, but purely out of practical curiosity for the mechanics here.
Incidentally, do you think Lutheranism's Charitable Missions could let them bribe the Afghan peacekeepers out of the way to finally unite Arabia? It certainly couldn't hurt to try!
