Why so Many Denominations?

Q: Why so Many Denominations?

A: She had DAUGHTERS

And upon her forehead was a name written, MYSTERY, BABYLON THE GREAT, 

THE MOTHER OF HARLOTS AND ABOMINATIONS OF THE EARTH....And I heard another voice from heaven, saying, Come out of her, MY PEOPLE, that ye be not partakers of her sins, and that ye receive not of her plagues. 

Revelation 17:5/18:4
