The mystery of the existing Church, in all its grades of dissent, having set forth and caused the belief of a temporal and local existence of the personated principles of Deity, as distinct and separate from ourselves, in imitation of the Pagan Mythology, and not as simulated beings; it is requisite, as matter of proof, sooth and truth, that a case of clear human history of the circumstances be first made out, the doing of which my knowledge, after trial, challenges; and if that could be done, the more difficult task would remain, to prove, that such beings, the authors of such circumstances, as could be historically proved, were super-human. If the first cannot be done, the clumsy mystery falls to the ground, as the Dagon of the day, before historical criticism: and if the first be done, and the second cannot bear the light of scientific and philosophical criticism, the mystery is still but a mummery, which belief can no longer prop, nor physical power farther propagate; it is thrown into the crucible of moral criticism, and men will not longer consent to believe that the same causes will demonstrate differing effects, nor that varying causes may be made to demonstrate the same effect. I have read in public prints of your creditable attendance at the Royal Institution of Albemarle Street, on the demonstrative Lectures of Mr. Faraday in the Science of Chemistry. When there, were you asked to believe anything? Was not everything demonstrated, so that the words were verified by the acts of the Lecturer? If Mr. Faraday had played you _hocus pocus_ or legerdemain tricks, as a pretence of chemistry, would you have been satisfied? If he had told you of strange and incomprehensible things, which he could not demonstrate, would you have believed?--I think not: I give you credit for a better state of mind. Take a lesson from the inference, and grasp this truth, that the Royal Institution in Albemarle Street is the best Church in the country, and is, in reality, the nearest existing approach to the Catholic Church of Christ. It would be rational, it would be wisdom, if all were spending their Church time at such lectures, who are old enough to receive such instruction.
