The creation is the Bible of the Deist. He there reads, in the handwriting of the Creator himself, the certainty of His existence and the immutability of His power, and all other Bibles and Testaments are to him forgeries.
Thomas PaineBut 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. ... Mystery is the antagonist of truth. It is a fog of human invention, that obscures truth, and represents it in distortion. 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.
Thomas Paine
