Pratt was at once commissioned, "by revelation and the laying on of hands," to preach the new Gospel, and was sent, also by "revelation" (Sec. 32, "Doctrine and Covenants"), along with Cowdery, Z. Peterson, and Peter Whitmer, Jr., "into the wilderness among the Lamanites." Pratt and Cowdery went direct to Rigdon's house in Mentor, where they stayed a week. Pratt's own account says: "We called on Mr. Rigdon, my former friend and instructor in the Reformed Baptist Society. He received us cordially, and entertained us with hospitality."* * "Autobiography of P. P. Pratt," p. 49. In Smith's autobiography it is stated that Rigdon's visitors presented the Mormon Bible to him as a revelation from God, and what followed is thus described:-- "This being the first time he had ever heard of or seen the Book of Mormon, he felt very much prejudiced at the assertion, and replied that 'he had one Bible which he believed was a revelation from God, and with which he pretended to have some acquaintance; but with respect to the book they had presented him, he must say HE HAD SOME CONSIDERABLE DOUBT' Upon which they expressed a desire to investigate the subject and argue the matter; but he replied, 'No, young gentlemen, you must not argue with me on the subject. But I will read your book, and see what claim it has upon my faith, and will endeavor to ascertain whether it be a revelation from God or not'. After some further conversation on the subject, they expressed a desire to lay the subject before the people, and requested the privilege of preaching in Elder Rigdon's church, TO WHICH HE READILY CONSENTED. The appointment was accordingly published, and a large and respectable congregation assembled. Oliver Cowdery and Parley P. Pratt severally addressed the meeting. At the conclusion Elder Rigdon arose and stated to the congregation that the information they that evening had received was of an extraordinary character, and certainly demanded their most serious consideration; and, as the apostle advised his brethren 'to prove all things and hold fast that which is good,' so he would exhort his brethren to do likewise, and give the matter a careful investigation, and NOT TURN AGAINST IT, WITHOUT BEING FULLY CONVINCED OF ITS BEING AN IMPOSITION, LEST THEY SHOULD POSSIBLY RESIST THE TRUTH." * Millennial Star, Vol. XIV, p. 47. Accepting this as a correct report of what occurred (and we may consider it from Rigdon's pen), we find a clergyman who was a fellow-worker with men like Campbell and Scott expressing only "considerable doubt" of the inspiration of a book presented to him as a new Bible, "readily consenting" to the use of his church by the sponsors for this book, and, at the close of their arguments, warning his people against rejecting it too readily "lest they resist the truth"! Unless all these are misstatements, there seems to be little necessity of further proof that Rigdon was prepared in advance for the reception of the Mormon Bible.
