Maybe not the biggest, but I think it's definitely way up there.
It's the transition from a cultural and intellectual climate like with Aquinas to a climate of unquestionably accepting dogma without connecting religious concepts to secular ones, which means not seeing the connection between things like sin, spiritual death, spirit, etc., and how they make sense in secular language, as well as where God and all related concepts "fit" into the world in general.
I've always held that most Christians and theologians around today are esoteric to themselves. They don't know what their own concepts even mean, and they're too busy just accepting the "right things" about God, as if he could be placated by a formula and a divine checklist of all the right things you need to accept without really understanding them at all. This pretty clearly is motivated by tribalism or fear: the desire to fit in for the sake of excluding others or trepidation at God to the point that our intellectual faculties aren't capable of working properly.
What we need is not so much arguments for God as a really relevant theism. A theoretical theism that bridges the gap between secular and spiritual. Just like evolution is unavoidably useful because it connects everything biological together through a theory, the same would be the case if God were actually made relevant and aspects of religion connected theoretically to things like happiness, pathology, ethics, and ontology.
