Heresies abound in the sectarian world. False doctrines are manifest on every hand. God is not a spirit essence, without body, parts, or passions, that fills immensity and is nowhere in particular present, for instance; nor is it true that revelation ceased with the ancient apostles.
But what of the true Church? Are there heresies within even that divine institution? Paul says such was the case among the Corinthians, and it is apparent that the same thing prevails in the modern kingdom of God on earth. Speaking of our day, Nephi said that "because of pride, and wickedness, and abominations, and whoredoms," all men have "gone astray save it be a few, who are the humble followers of Christ." Then pointing to these true saints, he added: "Nevertheless, they are led, that in many instances they do err because they are taught by the precepts of men."(2 Ne. 28:14.) That is, heresies are found in the Church today, even as in the meridian of time. For instance, what of the views of some on revelation, on the age of the earth, on the theories of organic evolution, on the resurrection of the sons of perdition, on a second chance for salvation, on whether God is progressing in truth and knowledge, and so forth?
