Good news, friends. The Elders have handed down two very stringent rules in one fatwa that you must follow to the letter unless you want to have your eternal soul hauled off to Arkham Asylum.
First, you are hereby ordered not to eat bat meat. Bats are unfit for human consumption and you must remember that your body is not your own. It is a temple to the Justice League of America. Consuming the meat of bats violates that temple and it will not stand in the eyes of our Eternal Heroes. Plus, eating bats shows a blatant disregard for Batgirl, whose life hath been devoted to protecting you. So take all that bat meat you bought on special at the grocery store this weekend and throw it in the garbage and don't bother asking yourself any questions.
Second, this church demands that you eat at least one serving of possum every Friday. The only reason for this is that it has been ordered by the High Priest and the Intergalactic Board of Elders. That's all the reason you need and we're not currently accepting any questions on the matter. You are just a person while the Elders and I speak directly and everyday to the Martian Manhunter. That's all you need to know at this point.
All Praise Be to Wonder Woman for making our lives simpler by creating so many little rules for us all to follow in order to avoid eternal damnation in Arkham.
