Joseph Smith baptized with the Holy Ghost. But Sidney knew not that he was heralding Joseph.
And the prophet himself was but as the voice crying in the wilderness of the great dark world: "Prepare ye the way for the second advent of earth's Lord." His mission was also to "make straight in the desert a highway" for the God of Israel; for Israel was going up,—following the angel of the covenant, to the chambers of the mountains.
He came with a great lamp and a great light in those days, dazzling to the eyes of the generation that "crucified" him in its blindness.
Joseph was the sign of Messiah's coming. He unlocked the sealed heavens by faith and "election." He came in "the spirit and power of Elijah." The mantle of Elijah was upon him.
Be it always understood that the coming of Joseph Smith "to restore the covenant to Israel" signifies the near advent of Messiah to reign as King of Israel. Joseph was the Elijah of the last days.
These are the first principles of Mormonism. And to witness of their truth this testament of the sisters is given, with the signs and wonders proceeding from the mission of Him who unlocked the heavens and preached the gospel of new revelations to the world, whose light of revelation had gone out.
But first came the famous Alexander Campbell and his compeer, Sidney Rigdon, to the West with the "lamp." Seekers after truth, whose hearts had, been strangely moved by some potent spirit, whose influence they felt pervading but understood not, saw the lamp and admired.
Mr. Campbell, of Virginia, was a reformed Baptist. He with Sidney Rigdon, a Mr. Walter Scott, and some other gifted men, had dissented from the regular Baptists, from whom they differed much in doctrine. They preached baptism for the remission of sins, promised the gift of the Holy Ghost, and believed in the literal fulfillment of prophesy. They also had some of the apostolic forms of organization in their church.
In Ohio they raised up branches. In Kirtland and the regions round, they made many disciples, who bore the style of "disciples," though the popular sect-name was "Campbellites." Among them were Eliza R. Snow, Elizabeth Ann Whitney, and many more, who afterwards embraced the "fullness of the everlasting gospel" as restored by the angels to the Mormon prophet.
But these evangels of a John the Baptist mission brought not to the West the light of new revelation in their lamp.
