"But don't be so fast, says one; don't you know that there are only about 197,000,000 of square miles, or about 126,000,000,000 of acres upon the surface of the globe? Will these accommodate all the inhabitants after the resurrection? Yes; for if the earth should stand 8000 years, or 80 centuries, and the population should be a thousand millions in every century, that would be 80,000,000,000 of inhabitants, and we know that many centuries have passed that would not give the tenth part of this; but supposing this to be the number, there would then be over an acre and a half for each person upon the surface of the globe." By eliminating the wicked, so that only one out of a hundred would share this real estate, he calculated that every Saint "would receive over 150 acres, which would be quite enough to raise manna, flax to make robes of, and to have beautiful orchards of fruit trees." The Mormon belief is stated by the church leaders to rest on the Holy Bible, the Mormon Bible, and the "Book of Doctrine and Covenants," together with the teachings of the Mormon instructors from Smith's time to the present day. Although the Holy Bible is named first in this list, it has, as we have seen, played a secondary part in the church ritual, its principal use by the Mormon preachers having been to furnish quotations on which to rest their claims for the inspiration of their own Bible and for their peculiar teachings. Mormon sermons (usually styled discourses) rarely, if ever, begin with a text. The "Book of Doctrine and Covenants" "containing," as the title-page declares, "the revelations given to Joseph Smith, Jr., for the building up of the Kingdom of God in the last days," was the directing authority in the church during Smith's life, and still occupies a large place in the church history. An examination of the origin and character of this work will therefore shed much light on the claims of the church to special direction from on high. There is little doubt that this system of "revelation" was an idea of Rigdon. Smith was not, at that time, an inventor; his forte was making use of ideas conveyed to him. Thus, he did not originate the idea of using a "peek-stone," but used one freely as soon as he heard of it. He did not conceive the idea of receiving a Bible from an angel, but readily transformed the Spaniard-with-his-throat-cut to an angel when the perfected scheme was presented to him. We can imagine how attractive "revelations" would have been to him, and how soon he would concentrate in himself the power to receive them, and would adapt them to his personal use.
