The Bible is vast, has terse or "poetic" language that is prone to misinterpretation, has many variants that rely on different translations or canonical versions, and has some big internal contradictions. Calling that a moral framework is lunacy, because anyone can cherry pick whatever they want because it's impossible to get a simple unified message out of it. Hence you have Catholics and Anabaptists, Mormons and Adventists, Christian Identity and zionist evangelicals, Westboro Baptist and faggot Unitarians, all calling themselves Christians.
