And this modern discovery will, at no distant day, revolutionize all systems of religious faith in existence, and either dissolve and dissipate them, or modify and establish them upon a more natural and enduring basis, expurgated of their dogmatic errors. Let us, then, labor to banish the wide-spread delusion believed and taught by a thousand systems of worship--Jew, Pagan and Christian--that "religion is of supernatural or divine origin," and the many ruinous errors; senseless dogmas and deplorable soul-crushing superstitions so thoroughly inwrought into the Christian system will vanish like fog before the morning sun, and be replaced by a religion which sensible, intelligent and scientific men and women can accept, and will delight to honor and practice. ADDRESS TO THE CLERGY. FRIENDS and brethren--teachers of the Christian faith: Will you believe us when we tell you the divine claims of your religion are gone--all swept away by the "logic of history," and nullified by the demonstrations of science? The recently opened fountains of historic law, many of whose potent facts will be found interspersed through the pages of this work, sweep away the last inch of ground on which can be predicated the least show for either the divine origin of the Christian religion, or the divinity of Jesus Christ. For these facts demonstrate beyond all cavil and criticism, and with a logical force which can leave not the vestige of a doubt upon any unbiased mind, that all its doctrines are an outgrowth from older heathen systems. Several systems of religion essentially the same in character and spirit as that religion now known as Christianity, and setting forth the same doctrines, principles and precepts, and several personages filling a chapter in history almost identical with that of Jesus Christ, it is now known to those who are up with the discoveries and intelligence of the age, were venerated in the East centuries before a religion called Christian, or a personage called Jesus Christ were known to history.
