A speech from the Hon. A. H. Stephens, Vice-President of the Confederate States of America spells out institutional racism, and the use of religion to justify it.
[T]he first government ever instituted upon the principles in strict conformity to nature, and the ordination of Providence, in furnishing the materials of human society … With us, all of the white race, however high or low, rich or poor, are equal in the eye of the law. Not so with the negro. Subordination is his place. He, by nature, or by the curse against Canaan, is fitted for that condition which he occupies in our system. The architect, in the construction of buildings, lays the foundation with the proper material-the granite; then comes the brick or the marble. The substratum of our society is made of the material fitted by nature for it, and by experience we know that it is best, not only for the superior, but for the inferior race, that it should be so.
It is, indeed, in conformity with the ordinance of the Creator. It is not for us to inquire into the wisdom of His ordinances, or to question them. For His own purposes, He has made one race to differ from another, as He has made “one star to differ from another star in glory.” The great objects of humanity are best attained when there is conformity to His laws and decrees, in the formation of governments as well as in all things else. Our confederacy is founded upon principles in strict conformity with these laws.
