Exactly, GF. You almost have to be a lawyer to see how a word with a specific definition behind it is used in one context, and then see how they'll use the same exact word with other loaded meanings tacked on within their own circles.
Repentance literally is doing a u-turn. But Mormon repentance means never committing the same sin again for what you repented. (Latter definition courtesy of Spencer Kimball)
Grace literally means a gift, as in a free gift from God. Mormon grace is what kicks in from God eventually...but only after men have done everything they could do.
Priesthood Biblically is man's representative before God. Mormons turn that around and define it as God's representative to man.
True spiritual authority is what originates from the ultimate true God of the universe. LDS authority is what Joe Smith had. When you ask LDS where he got his authority from, they say Elohim & Jesus Christ. When you ask them where Elohim got his authority from, the honest Mormon will tell you Elohim's god (boy what a strange phrase to even utter).
When you ask them where that god got his authority from, they won't answer you -- if you've even gotten this far in the discussion. The reason they won't answer you, is 'cause they know where you're going with it. There is no ultimate authority in the Mormon church, because there's no original ultimate god. (They don't the god who passed the buck to begin with).
I think Elsie's best post on this thread is #738 where he compares historic Christianity's definition of common terms and joey-come-lately Mormon redefinitions...see particularly sin, repentance, grace, gospel, and hell.
So much for that 70 * 7 thingy!
"If you are GOING to sin; at least try one you've never done before!"
