“American Christianity is becoming less intellectual and more mystical over time, he explains”
Nonsense, American Christians and Christians from time recorded believe in all manner of miracles, from creation out of nothing to chariots of fire to water into wine to the RESURRECTION, lest we forget -
what poppycock this denier is spouting. Christianity without miracles is not Christianity.
Remember how the serpent in the Garden challenged Adam: "Did God really say that?" (Yes, He really did.) Satan wants us to doubt. Resist him, and he will flee.
