One of the wickedest offenses possible to commit against the Church is the stirring up of doctrinal discord and division, a thing the devil encourages to the utmost. This sin usually arises in certain haughty, conceited, self-seeking leaders who desire peculiar distinction for themselves and strive for personal honor and glory. They will give honor to no one, even when they recognize the superiority of his gifts over their own. In their envy and vengefulness they seek occasion to create factions and to draw people to themselves. Many are deceived and immediately respond to the new doctrine presented in specious words by presumptuous leaders thirsting for fame. Many weak but well-meaning ones fall to doubting; many become reckless pleasure lovers, disregarding all religion and ignoring the Word of God. Even they who are called Christians come to have hard feelings against one another, their love grows cold and faith is extinguished. Christians, then, should be careful to give no occasion for division and discord. They must strive against them, submitting to all suffering and performing all demands to prevent, so far as possible, any disturbance of the unity of doctrine, of faith and of Spirit.
