The good news is someone has created just such a handout. They have printed some and will mail a few at no charge to anyone who sends their name and address to email@example.com. I had nothing to do with this effort, but I think it is worthwhile and helpful, so I agreed to publicize it here.
This handout attempts to show the pattern throughout history of truth being revealed and then repeatedly corrupted so that there must be a movement, like the Protestant Reformation, to return to the original. It attempts to be non-offensive to both Christians and LDS and yet it also points out some of the problems that cause the need to preserve the restoration.
NOTE: This document is not, and has nothing to do with, the Guide & Standard/Statement of Principles project. This is not a statement of principles, nor is it a guide and standard; rather it is merely a historical introduction to the Lord's work, useful as an introduction.
