It will be seen from the foregoing sketch of this celebrated man, that so far as scholarship and trained ability in religious controversy is concerned, he was competent to analyze and make a severe criticism of the Book of Mormon. Before going into that, however, I think there is one other fact bearing on his career that should be noted. It will perhaps be remembered that Walter Scott and Sidney Rigdon were associated with Mr. Campbell in his reform operations in the state of Pennsylvania and Ohio. Up to 1830, the last named gentleman was as energetic in the interests of the "Disciples" as Mr. Scott or Mr. Campbell. Cardinal points in the reformation proposed by these gentlemen were, first: the recognition of the Bible as the only creed of the church; and after that faith in God and Christ, and the Holy Spirit; repentance of sin, and baptism in water by immersion for the remission of sins. It will be seen at once that in these doctrines the reformers were really preaching a number of the first principles and ordinances of the gospel; and when Sidney Rigdon became interested in Mormonism and visited the Prophet Joseph in New York, December, 1830, a revelation was given through the Prophet to Sidney Rigdon, in which the Lord claimed this reform work, in a way, as his: Behold, verily, verily, I say unto my servant Sidney, I have looked upon thee and thy works. I have heard thy prayers and prepared thee for a greater work. Thou art blessed, for thou shalt do great things. Behold, thou wast sent forth, even as John, to prepare the way before me, and before Elijah which should come, and thou knewest it not. Thou didst baptize by water unto repentance, but they received not the Holy Ghost. But now I give unto thee a commandment, that thou shalt baptize by water, and they shall receive the Holy Ghost by the laying on of hands, even as the apostles of old. [2]
