I’ve noticed that most groups considered as a cult, teach there was an apostasy of the Christian church, causing that true church to disappear from the face of the earth. Those groups also teach that the Bible had been tainted and corrupted by men.
Latter-day Saints do not consider their church a cult. But do believe in a Great Apostasy.
Let’s see what Jesus has to say about that? Will you please read Matthew 16:18?
“And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.”
