“The plain truth of false doctrine has been the chosen engine which Satan has employed in every age to stop the progress of the Gospel of Christ. Finding himself unable to prevent the Fountain of Life being opened, he has labored incessantly to poison the streams which flow from it. If he could not destroy it, he has too often neutralized its usefulness by addition, subtraction, or substitution. In a word he has ‘corrupted men’s minds.’”
