Odd that it hasn’t occurred to me before something which, now being recognised, seems obvious - I’d like to think this cognitive failure stems from the media’s politically correct noise doing such a good job of burying info it doesn’t want to hear or see - or maybe I’m just stupid - I dunno - but the obvious revelation that just sort of popped into my head is that if the claims of Christianity are true, then Islam must be a false religion - and vice versa - Islam can only make sense if the divinity of Jesus is denied - Christianity can only make sense by denying that Allah is the one true God because that’s the only way to explain him not informing Muhammad about the divinity of his son - therefore, logically neither religion can tolerate the other and still hope to express a coherent understanding of some deity’s creation. This is so obvious as to be almost a tautology - and yet, in the Christian world at least, that fact is practically ignored - indeed, some Christians reach out to Muslims as if they shared some sacred bond with them, which is a ludicrous absurdity - Muslims on the other hand seem to be much more cognizant of this inherent tension between the two faiths and I’d say that’s not just because the Koran clearly identifies the problem as a problem, as of course it must since the Gospels predate it by several hundred years and undermine its central point.
No, I’d say the reason this inherent tension between the two faiths seems to go unnoticed in the Christian world is because, unlike Islam, Christianity as an apolitical religion is well suited to running on faith alone and therefore tends to be much more tolerant of certain beliefs ‘not making sense’ - a true Christian, certainly in the modern era, simply doesn't care about making sense - contrarily, the highly political nature of Islam makes it much less tolerant of accepting a charge of incoherence because such a charge would not just render the faith incoherent but also the entire culture which props it up.
Point being the takeaway is: Islam and Christianity are not just perforce incompatible given the tenets they espouse - those tenets, if taken seriously, logically pose an existential threat to the validity and credibility of the other - but Christians tend to look past this highly problematic conflict of interests because Christianity's apolitical nature puts practically all justification for its credo in an individual’s faith in the redeeming power of the resurrection of Christ and the grace that comes of it - whereas Islam depends a great deal on an active political component to get to where it wants to go.
As for me, from an epistemological point of view, I believe all religions are false constructs - understandable consequences of natural human behavior and psychology for sure and therefore not necessarily illegitimate per se - but false regardless - still, I do not embrace atheism as a sensible position for the simple reason I can’t prove the claims of the various religions to be false and so the potentiality of me being wrong clearly exists, no matter how small I may consider that potentiality to be - nevertheless, by the same token believers have little choice but to accept that for the very reasons I can’t prove religions to be false things neither can the faithful prove they are not.
