This is a Christian named Frank Schaeffer speaking:
The Mainstream culture does not take stock of the fact that we have within our culture a subculture which is literally a fifth column of insanity, which is bred from birth, through home school, Christian school, evangelical college, whatever, to reject facts as a matter of faith.
“Can Christianity be rescued from Christians?”
What is a fifth column? A Fifth column is “a group of people who clandestinely undermine a larger group such as a nation from within, to help an external enemy.”
