Manism

As to the Christian system of faith, it appears to me as a species of atheism; a sort of religious denial of God. It professes to believe in a man, rather than in God. It is a compound, made up chiefly of manism, with but a little deism, and is as near to atheism as twilight is to darkness.

Now, one of the worst features of Roman Catholicism is its popery, or manism. The Pope is the soul of the whole system. Remove him, therefore, and nothing remains but a headless and soulless body, which, like the tail of the snake, may writhe awhile after its head is severed. So with respect to parts of Protestantism. Remove the manism from them, and Christians are at once together and one in Christ. Manism, therefore, is the great obstacle to Christian purity, unanimity, and success.
