Baha'i
The Old Testament is Classic Coke, the New Testament is New Coke, and Islam is Pepsi. All inter-religious strife is about brand loyalty - plain and simple.
I'm pretty sure this simple idea has been thought of before... only rather than Cokes and Pepsi in terms of chapters in the same book...
It is an article of our Faith that there is but one religion, and the Source of that religion is the Creator, God. Different religions are but progressive chapters in that book of religion. Bahá'u'lláh states, "That the divers communions of the earth, and the manifold systems of religious belief, should never be allowed to foster the feelings of animosity amongst men, is, in this Day, of the essence of the Faith of God and His Religion. These principles and laws, these firmly established and mighty systems, have proceeded from one Source, and are the rays of one Light. That they differ one from another is to be attributed to the varying requirements of the ages in which they were promulgated."
