13. _Philosophy_.--The science of philosophy, in its matured aspect, is of modern origin, and furnishes the true explanation for many of the "mysteries of godliness," and other mysteries of the Christian Bible, which, by the illiterate writers of that age, were ascribed to the direct manifestation of deific powers. They are now known to be natural occurrences, instead of supernatural, as assumed by the writers. The Bible story of the rainbow furnishes one example. Moses must have been ignorant of philosophy when he selected the rainbow as an evidence there should be no rain in the future insufficient quantities to inundate the earth again, when it is known that the rainbow is a certain evidence of rain, as it is produced by the rain in the act of falling. This is but one of many errors which the ignorant, illiterate Bible writers have made for want of knowledge on scientific subjects, such as the history of creation, the story of the flood, &c. The several cases in which thunder is spoken of as being the voice of God disclose great ignorance of philosophy; and several instances in which God promises to take away the sickness of the people evince an entire ignorance of the natural laws which control health and disease. (See Exod. xxiii. 25; Deut. vii. 15.) 14. _Mathematics_.--The Bible is deficient in many cases with respect to the correct observance of the rules and principles of mathematics. Its assumption that there can be but one God, and at the same time acknowledging three, furnishes a striking proof of this. Its enumeration of the families and tribes furnishes another evidence of this. Its calculation of numbers rarely coincides with the names. For example: Matth., in his gospel, states there are forty-two generations from David to Joseph; but his list of names only makes forty-one. And Matthew says, "From Adam to David are fourteen generations;" but, by counting his list of names, we find but thirteen. The date of Methuselah's birth and his age, when compared together, extend his age ten months beyond the inauguration of the flood. How he sustained life, and avoided drowning during that time, must be one of the "mysteries of godliness." These are a few specimens of Bible mathematics.
