I think your analysis fails at the step where you propose a universalized, objectively correct morality. Please show me the empirical test for this. Or is it just about whether you feel your actions accord with the word of God? Because even then you're just practicing moral relativism and waving your hands at a book composed by fallible humans, all of whom were doing the same, all the way back to before the canons were written. Is it because the book is supposedly divinely-inspired? How do you know the correct divinity inspired the correct people in the correct way? even standing on the soapbox of "well uh uh uh of course my religion is the correct one you smelly heretic" you literally have nothing to go off of except your own feelings and perspective.
So, in short, I don't find your position very convincing. Also, if Christians were some sort of uniquely enlightened group with special access to the metaphysical groups of the universe, why do they keep falling into the same patterns of behavior as all the other humans who don't have this divine guarantee? Like, if religion was actually some special basis upon which to erect a human morality, why does it achieve such similar outcomes as every other basis? If it's because "humans are fallible and don't always accord perfectly to the perfect divine plan allocated to them," then, again, how is that exactly non-relativistic? Is it because the book exists as some sort of measuring stick by which to determine the essential goodness of someone? Because even that depends on the fallible interpretation of the interpreter, unless you presuppose some special person who is blessed with divine discernment to determine the actual divinely-approved interpretation.
It all ultimately devolves to "you just gotta have faith bro." I do not have faith in an entire group of people thumbing their noses at everyone else like their shit doesn't stink. Antisemitism and hate is literally built into every canonical version of Christianity by way of the Churchfathers.
Maybe we should judge Christianity on the outcomes of Christians, instead of on the most compassionate and kindest way they beg us to take their positions. Actually looking at the facts reveals something most priests blush about... we're all equally clueless. The major difference between me and a Christian is that I don't actively look forward to dying, in the hopes I'll get The Good Ending and have an infinitely good time after I've perished in service to people who have an incentive to get me to live my life in service to them.
