We do have a pretty good understanding of some necessary claims, like “It is necessarily true that 2+2=4.” Asking “why is that necessary?” has a fairly good answer: “Because it’s what the symbols mean, and if you deny it you soon find yourself in incoherence.”
Whereas, one does not seem to fall into incoherence when asserting “There is no such thing as an omniscient, omnipotent being whose son died by crucifixion.” (I dare say one teeters upon that chasm when asserting the opposite!)
