Look, let’s talk a bit about scripture and the prophets who largely shaped scripture. Christians, of course, accept all of the Jewish prophets, but ascribe their messages to something other than the Jews themselves understand them to have been about. (Surprising, really, that Christians should know so much more about Jewish prophets than Jews themselves, but what do I know?)I can only refer you to the Writings of Baha'u'llah and Abdul-Baha Reading them are what convinced me of the truth. That is the method I used.
I didn't find any mistakes.
"Every word that proceedeth out of the mouth of God is endowed with such potency as can instill new life into every human frame, if ye be of them that comprehend this truth." Baha'u'llah
Of course, Christians added their own prophets – Jesus, Paul, and I would venture to say the Gospellers. And these Christian prophets fundamentally redefined the religion known until then. The Jews, of course, were not impressed, but then, why should they be – they’d been living with their religion for dozens of generations by that time, and religion, as we know, is hard to expunge. And the consequences were often terrible.
Muslims believe the first prophet was also the first human being, Adam (Adem). Many of the revelations delivered by the 48 prophets in Judaism and many prophets of Christianity are mentioned as such in the Quran but usually in altered form and with different names. For example, the Jewish Elisha is called Alyasa, Job is Ayyub, Jesus is Isa, etc. The Torah given to Moses (Musa) is called Tawrat, the Psalms given to David (Dawud) is the Zabur, the Gospel given to Jesus is Injil). (For reasons known only to themselves, of course, none of the seven Jewish Prophetesses are mentioned in the Quran as prophets.)
Of course, Islam added its own prophets, notably Mohammed “the Seal of the Prophets,” who fundamentally changed the meaning of everything that had been understood by both Christians and Jews before. And the Christians and Jews were not impressed, but then, why should they be – they’d been living with their religions for dozens of generations by that time, and religions, it is well known, are remarkably difficult to erase. And the consequences have been awful for a very long time.
Bahá’ís believe that Throughout the ages, God has sent Divine Messengers known as Manifestations of God—among them Abraham, Krishna, Zoroaster, Moses, Buddha, Jesus Christ, Muhammad, and, in more recent times, the Báb and Bahá’u’lláh – to cultivate humanity’s spiritual, intellectual and moral capacities. Following the coming of a Manifestation of God extraordinary progress occurs in the world. Reaching to the roots of human motivation, His teachings awaken in whole populations capacities to contribute to the advancement of civilization to an extent never before possible.
While Bahá’í belief looks remarkably “Christian,” it is in actuality quite different again, and Christians, Muslims and Jews aren’t generally all that interested in it. And by the way, the consequences haven’t been all that wonderful in places like Iran.
Now, one of the things all these religions share is a belief in an omniscient and omnipotent deity. And if that is the case, they must believe (although they probably are not aware that they believe) that this deity has done all of this – changing His mind repeatedly and causing all the confusion and dreadful consequences that have resulted – either on purpose or without caring about those consequences. (The other choice, of course, is that the deity is not in fact omniscient – quite a bit removed from omniscience, actually – but I don’t think this will be acceptable to believers.)
If those religions all believe what they believe they believe, then this is undeniable, even though none of them will give it any thought, because giving it the thought it deserves would be dreadfully uncomfortable. But I repeat it is logically inescapable, if they really do believe what they think they believe, that the religious strife that has caused untold misery and death to millions upon millions of human beings is the deliberate result of how an omniscient and omnipotent deity chose to express himself to humanity.
I myself find that remarkably difficult to accept. But what do I know?
