Wow! A fellow Salt Laker! I can't recall ever using that "cop-out" myself. I would be more inclined to explain apparent contraditions, etc. by saying, "There's more to it than the Bible says." Just as a quick "for instance...", I have heard many, many Christians claim that Jesus' statement in Luke 20:34-36 ("The children of this world marry, and are given in marriage. But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage: Neither can they die any more: for they are equal unto the angels; and are the children of God, being the children of the resurrection.") is a direct contradiction of the LDS belief in the eternal nature of the marriage covenant. I certainly don't think there is a translation error in this passage, but I don't believe that the Bible provides us with all of the finer points of this doctrine. When understood in the context in which we believe this statement was made, there is no contradition between LDS belief and what Jesus said. In my opinion (and I'm sure it is shared by many of my Faith), there are fewer actual translation errors than omissions.
