To keep a person on the Scientology path, feed him a mystery sandwich.
L. Ron Hubbard, Founder of Scientology
The most vital element in the study of Christian theology is a radical commitment to mystery.
Herman Bavinck, Dutch Reformed theologian
In order to be effective a doctrine must not be understood, but has rather to be believed in. We can be absolutely certain only about things we do not understand. A doctrine that is understood is shorn of its strength. Once we understand a thing, it is as if it had originated in us. And, clearly, those who are asked to renounce the self and sacrifice it cannot see eternal certitude in anything which originates in that self.
