But though every created thing is, in this sense, a mystery, the word mystery cannot be applied to moral truth, any more than obscurity can be applied to light. ...

Truth never envelops itself in mystery, and the mystery in which it is at any time enveloped is the work of its antagonist, and never of itself.

Of all the systems of religion that ever were invented, there is no more derogatory to the Almighty, more unedifying to man, more repugnant to reason, and more contradictory to itself than this thing called Christianity.
