If mankind were capable of deriving the most obvious lessons from the facts before them, in opposition to their preconceived opinions, Mormonism would be to them one of the most highly instructive phenomena of the present age. Here we have a new religion, laying claim to revelation and miraculous powers, forming within a few years a whole nation of proselytes, with adherents scattered all over the earth, in an age of boundless publicity, and in the face of a hostile world. And the author of all this, in no way imposing or even respectable by his moral qualities, but, before he became a prophet, a known cheat and liar. And with this example before them, people can still think the success of Christianity in an age of credulity and with neither newspapers nor public discussion a proof of its divine origin!
