Is it desirable that all should be exactly alike in their religious convictions? Is any such thing possible? Do we not know that there are no two persons alike in the whole world? No two, trees, no two leaves, no two anythings that are alike? Infinite diversity is the law. Religion tries to force all minds into one mould. Knowing that all cannot believe, the church endeavors to make all say they believe. She longs for the unity of hypocrisy, and detests the splendid diversity of individuality and freedom.
