Wednesday, June 12, 1812, having been selected, Elder Luce, in company with Elder Henry Spears, called at Thomas Campbell’s on their way to the place chosen for the immersion, which was the deep pool in Buffalo Creek, where three members of the Association had formerly been baptized. Next morning, as they were setting out, Thomas Campbell simply remarked that Mrs. Campbell had put up a change of raiment for herself and him, which was the first intimation that they also intended to be immersed. Upon arriving at the place, as the greater part of the Brush Run Church, with a large concourse of others, attracted by the novelty of the occasion, were assembled at David Bryant’s house, near the place, Thomas Campbell thought it proper to present, in full, the reasons which had determined his course. In a long address he reviewed the entire ground which he had occupied, and the struggles that he had undergone in reference to the particular subject of baptism, which he had earnestly desired to dispose of, in such a manner that it might be no hindrance in the attainment of that Christian unity which he had labored to establish on the Bible alone. In endeavoring to do this he admitted that he had been led to overlook its importance, and the very many plain and obvious teachings of the Scriptures on the subject; but having at length attained a clearer view of duty, he felt it incumbent upon him to submit to what he now saw an important Divine institution. Alexander afterwards followed with an extended defense of their proceedings, urging the necessity of submitting implicitly to all God’s commandments, and showing that the baptism of believers only was authorized by the Word of God.
