Manly P. Hall

This order preserved to the end the high ethical and rational standards which confer honor upon a teaching. The Church therefore attacked Gnosticism vigorously and relentlessly, recognizing these mystical philosophers as being the most formidable adversaries to the temporal power of Christian theology.
