"Mormons are considered conservative Christians."
=========
By who? Mormons? The "Conservative Christians" I know do not consider Mormons to be a True Christian Denomination because a number of their beliefs come from "revealed revelations that were revealed to their founder" that actually contradicts the writings of the Early Christian Church. 
-
There are a number of cults that won't reveal all their "secrets" until and unless you work your way up in the hierarchy. 
-
True Christianity is different. We have the Bible. That's it. Go to any bookstore, buy a Bible....ten bucks or less. Go to many motel rooms and take the Bible....for free. Come to my church and we'll give you one....for free.
-
We don't have "secret books" that explain "secret messages" that only the "upper echelon" are privy to. And if you find a church that has "secret books" that contain "secret messages" that only the "enlightened in that church" are privy to....that is a cult.

The Bible has no hidden secrets.
