Im my experience bahai often ignore the points, the specific contradictions which can be cited. That is the quran would indicate Christ was a mere creature who in no way was equal to God. Yet in the new testament Jesus Christ is not only our creator who is worshipped by his apostles, he is the one to whom forgiveness of sins is due to (Which the Quran says can only come from allah), he is the one salvation belongs to and that all judgement belongs to the son. Bahai do tend to gloss over these differences and not address tehm and still claim that there is no contradiction, they only do that by ignoring the contradictions.
That being said I disagree with this idea of “rising above difference.” What does that mean exactly? That unity is more important than truth? The contempt Christ and the early church had for the paganism around them would suggest to me that truth is worth more than unity for its own sake. What difference are we supposed to rise up and over? Should I expect the bahai to accept me worshipping Christ as God whom you view as a mere manifestation who is not God? Should you expect me to not take issue when you deny who I view as God as God? So what is this transcendence other than ignoring the differences and claiming that there is something else?
Simply making a claim doesn’t mean I should take anyone seriously. There have been a lot of attempts by many people to get the quran and bible, and Christianity and islam to be in harmony and usually they do this at the expense of one ideology of the other. Christ is not God, Christ is God, Christ did not die, Christ did die.
