We're not talking about God as absolute truth though.
We're talking about God as personified by Jesus, Allah, Vishnu etc. We can acknowledge absolute truth without throwing God into it.
Those personifications of God, as well as the doctrines that go along with it, are an obstruction to truth. If you ask me, the personification of God spawns a bigger mystery. Which of the million belief systems has got him right, if any? Why doesn't God make himself evident to people? Who created God?
Personifying God is presumptuous, dishonest, and narrow-minded. It stifles unity, knowledge, and freedom.
