I was born and raised SDA until God opened my eyes to the solid Gospel.  Adventists are correct in saying that the Sabbath was never changed to Sunday. However, if one understands the covenants and what Christ completed on the cross, then you do not fall for the straw man arguments.  Like it or not, the SDA church has some wonderful, wonderful people yet there are cult-like qualities with one being they claim to be the only true church.  Their evangelism is over 90% sheep stealing from other Christian churches.  While they sound very normal in many respects, there are other doctrines such as the Investigative Judgment and their prophet as a "continuing and authoritative source of truth" that you don't realize right off.
