Lots of people screw around with what the steps say. The bottom line is an HP is open ended.
Lots of "we agnostics" is very condecending, but if you look at it from another perspective..there is room for the agnostic. The aithiest has a harder row to hoe, but the steps still have room for them.
Historically the first AA members were from a christian background, but that doesn't mean the solution is only for christians. It was simply couched in terms that they shared in common.
