A Christian can believe that God 'ordained' the 'powers that be' - including political rulers and slaveholders - for purposes too deep for us to understand fully, and that while they last we must provisionally accept them; but that they were not meant to last forever.
Joseph SobranLiberalism is really piecemeal socialism, and socialism always attacks three basic social institutions: religion, the family, and private property. Religion, because it offers a rival authority to the state; the family, because it means a rival loyalty to the state; and property, because it means material independence of the state.
