Sadly, sometimes members aren't very diligent with Home Teaching or Visiting Teaching for Sisters. Are you assigned as a Home Teacher and do you visit other members? Is your wife assigned and does she visit? Do you hold the Priesthood? Are you an endowed member of the Church? Any callings? Do you attend or did you attend Gospel Principles? I often misplace my membership record, but the Ward Clerk can provide it for you....just ask and the Handbook of Instructions is on LDS.org. Odd...it is teachings of past Prophets and the teachings are usually about being clean and worthy, or having gratitude, serving others, faith etc. Pretty basic concepts... Joseph Smith did have many wives as did many others...ordained and commanded by the Lord. It was a principle based in righteousness and perhaps difficult to understand for some today. The church doesn't keep or hide anything from anyone. There are volumes of history available to anyone that wishes to read it. That said, church history is often misinterpreted and really has little or nothing to do with the Gospel. there are some that would seek to have you focus on why JS had multiple wives or (insert whatever bothers you) and while history is both riveting and sometimes confusing it is not as important as the Atonement and learning who we are and who we have the potential of becoming. Before you allow these things to derail you, schedule an appointment with your Bishop and discuss what troubles you with him. Spiritual things are discerned by the Spirit.....
