You missed the point again, I don’t think you read the block quote.
This isn’t anything to do with nihilism or Christianity. As the link and the quote mention this is about some apparent higher reality, one that is beyond logic since the Absolute does not “make sense” which is why they speak of it in contradictory terms. This is about the possibility of living in some kind of illusion and not according to what is true. It has little or anything to deal with the easily shut down idea of Christianity and God. It’s about how all our concepts and ideas don’t describe the true reality.
