How can you belong to a religion?

Human psychology denotes that every mind has the potential to perceive things differently, so how do we know we're worshiping the same God? An example of this would be the different factions of Christians going around, some who love all creatures great and small and others who are anti-gay etc.

I went to church expecting to see like-minded people and all I got were a bunch of simple, ugly, fat old women.

Don't be dissing the bible.
So she discovered her whoredoms, and discovered her nakedness: then my mind was alienated from her, like as my mind was alienated from her sister. Yet she multiplied her whoredoms, in calling to remembrance the days of her youth, wherein she had played the harlot in the land of Egypt. For she doted upon their paramours, whose flesh is as the flesh of asses, and whose issue is like the issue of horses. Thus thou calledst to remembrance the lewdness of thy youth, in bruising thy teats by the Egyptians for the paps of thy youth.
Fucking beautiful poetry right there.
