It was very pleasant for the slave-owners to be taught that slavery enjoyed divine sanction. The doctrine had other apostles than Mr. Calhoun. Unhappily it came to form part of the regular pulpit teaching of the Southern churches. It was gravely argued out from the Old Testament that slavery was the proper condition of the negro. Ham was to be the servant of his brethren; hence all the descendants of Ham were the rightful property of white men. The slave who fled from his master was guilty of the crime of theft in one of its most heinous forms. So taught the Southern pulpit. Many books, written by grave divines for the enforcement of these doctrines, remain to awaken the amazement of posterity. The slave-owners inclined a willing ear to these pleasing assurances. They knew slavery to be profitable; their leaders in Church and State told them it was right. It was little wonder that a fanatical love to slavery possessed their hearts. In the passionate, ill-regulated minds of the slave-owning class it became in course of years almost a madness, which was shared, unhappily, by the great mass of the white population. Discussion could no longer be permitted. It became a fearful risk to express in the South an opinion hostile to slavery. It was a familiar boast that no man who opposed slavery would be suffered to live in a Slave State; and the slave-owners made their word good. Many who were suspected of hostile opinions were tarred and feathered, and turned out of the State. Many were shot; many were hanged; some were burned. The Southern mobs were singularly brutal, and the slave-owners found willing hands to do their fiendish work. The law did not interfere to prevent or punish such atrocities. The churches looked on and held their peace.
