The changes and improvements in religious ideas now observant in the most intelligent portion of the community, are due in part to the rapid progress of scientific discovery and the dissemination of scientific knowledge in Christian countries. The explorer in the field of religious history, however, comes in here for his meed of praise. New stores of historic facts and data may be reckoned among the recent acquisitions of the laborious archeologist; new fountains of religious history have recently been unsealed, which have had the effect to reveal many errors and false claims set up for the current religion of Christendom--a religion long regarded as settled and stereotyped. For many centuries subsequent to the establishment of the Christian religion, but little was known by its disciples of the character, claims and doctrines of the oriental systems of worship. These religions, in fact, were scarcely known to exist, because they had long been veiled in secrecy. They were found, in some cases, enshrined in religious books printed or written in a language so very ancient and obscure, as to bid defiance for centuries to the labors of the most indefatigable, profound and erudite archeological scholar to decipher it. That obstacle is now partially surmounted. The recent translation for the first time of the Hindoo Vedas into the English language (the oldest bible now extant or ever written) has revealed to the unwelcome gaze of the Christian reader the startling fact that "the heathen" had long been in possession of "holy books," possessing essentially the same character, and teaching essentially the same doctrines as the Christian bible--there being, as Horace Greeley expressed it, "No doctrine of Christianity but what has been anticipated by the Vedas." (See Vol. II., Chap. i, of this work.) If, then, this heathen bible (compiled, according to the Christian missionary, Rev. D. G Allen, 1400 B. C.), contains all the doctrines of Christianity, then away goes over the dam all claim for the Christian bible as an original bible as an original revelation, or a work of divine inspiration. Bibles are thus shown to be of heathen and human origin, instead of heavenly and divine authorship, as claimed for them by their respective disciples--the Christian bible forming no exception to this statement. The latter, being essentially like other bibles, it must, of course, have had the same or a similar origin--a fact which, though it may be new and startling to millions, will be universally accepted as truth before the lapse of many generations, and a fact which confronts with open denial the claims of two hundred millions of Christian professors, who assert with unscrupulous boldness that every doctrine, principle and precept of their bible is of divine emanation. How utterly groundless and untenable is such a claim when arranged by the side of modern discoveries in religious history!
