[1] The Methodists and Baptists, it is well known, divided directly upon the subject of slavery; and the Presbyterians mediately upon a question of constitutional law; but there is reason to believe that the slavery agitation in the Presbyterian Church precipitated a division, which otherwise would probably have been averted. Two striking phenomena remain to be noticed and accounted for. Amid all the conflict of opinion and feeling upon this subject,--which was inseparable from doctrines so utterly at war with the practices of the country--a conflict which at an early period found its way into the halls of legislation, civil and ecclesiastical, and has not ceased to the present time to modify the federal politics of the country,--the African population has yielded only to certain physical and moral laws as to the place of its location; whilst the institution of slavery, which embodies the great mass of that population in the country, has held on the even tenor of its way, unchecked in the slightest degree by the antagonistic doctrines and sentiments which have warred so fiercely against it, and which at so many periods have threatened the country with a legion of disastrous consequences. In the first place, the African population has gradually receded to those sections of the Union which, from their climate and soil, were better adapted to slave labor. Why did not the abstract opinions and sentiments set forth by Mr. Jefferson and the M. E. Church, and which are supposed to have given birth to the emancipation laws of the Northern States, operate to retain within those States the large portion of slave population then held, and secure their practical freedom? Why did they escape the supposed charity of these doctrines, and find their way, not as freemen, but as slaves, to a climate and soil more congenial to their nature and destiny? Are these doctrines real abstract truths, as their advocates profess to believe them to be? Then they are fundamental--they are vital--they are life-giving, and can never fail to impress their own essential character upon every system to which they are applied. The citizens of the Northern States adopted these doctrines. Then it was an affair of conscience. Emancipation laws were said to be the result. But that these laws, supposed to be founded in the belief of certain great abstract truths, which secured to the African his civil freedom, should operate only to transfer him to a climate and soil better suited to his condition as a slave, is a phenomenon for which the hypothesis does not account. And again, the institution itself, of domestic slavery, by reason of causes which are evidently, though mysteriously, at work, is this day more firmly grounded in the confidence of the great mass of the Southern people, and more extensively ramified and interlocked with other civil institutions of the whole country, than at any former period of its
