He and his father, Thomas Campbell, renounced the Presbyterian system, and were immersed, in the year 1812. They, and the congregations which they had formed, united with the Redstone Baptist association, protesting against all human creeds as bonds of union, and professing subjection to the Bible alone. This union took place in the year 1813. But, in pressing upon the attention of that society and the public the all-sufficiency of the _sacred_ Scriptures for every thing necessary to the perfection of Christian character,—whether in the private or social relations of life, in the church, or in the world,—they began to be opposed by a strong creed-party in that association. After some ten years debating and contending for the Bible alone, and the apostles’ doctrine, Alexander Campbell, and the church to which he belonged, united with the Mahoning association, in the Western Reserve of Ohio; that association being more favorable to his views of reform. In his debates on the subject and action of baptism with Mr. Walker, a seceding minister, in the year 1820, and with Mr. M’Calla, a Presbyterian minister of Kentucky, in the year 1823, his views of reformation began to be developed, and were very generally received by the Baptist society, as far as these works were read. But in his “Christian Baptist,” which began July 4, 1823 his views of the need of reformation were more fully exposed, and, as these gained ground by the pleading of various ministers of the Baptist denomination, a party in opposition began to exert itself, and to oppose the spread of what they were pleased to call heterodoxy. But not till after great numbers began to act upon these principles, was there any attempt towards separation. After the Mahoning association appointed Mr. Walter Scott an evangelist, in the year 1827, and when great numbers began to be immersed into Christ, under his labors, and new churches began to be erected by him and other laborers in the field, did the Baptist associations begin to declare non-fellowship with the brethren of the reformation. Thus by constraint, not of choice, they were obliged to form societies out of those communities that split, upon the ground of adherence to the apostles’ doctrine. The distinguishing characteristics of their views and practices are the following:—
