A couple of months ago I was asked for a list of books to help a former Mormons transition to Protestantism. I reached out to some friends and we came up with this list.These books are listed in order of complexity and depth, starting with the easiest to read.
I also STRONGLY recommend getting a modern English translation of the Bible. I love the King James Version and I think it’s a great translation, I recommend it to all my 400 year old friends. The English language has evolved and some of the phrasing in the KJV is archaic which makes it more difficult to understand. The newer translation were all created consulting the oldest known manuscripts of the Bible and were translated from the original languages so you can trust them to be accurate. Fears of the “Telephone Game” are misplaced. I almost always use the NIV. I also highly recommend reading the Bible in a paraphrase known as “The Message”. It’s available for free on the YouVersion Bible App created by LifeChurch.tv.
I recommend a fresh reading of Romans, Galatians and Hebrews with an attempt to dismiss everything you’ve been taught about these scriptures. Try to read them as if this is the first time you’ve read. If you can read them each in one sitting I think your experience will be even better. Don’t view the chapters as natural stopping points.
Lastly there is a study program called LDS Transitions that was made by Christians in Utah who saw a need for it based on the large number of people that have started to transition out of the LDS church.
My favorite book for all Christians is “The Divine Conspiracy” by Dallas Willard. It’s probably not the best book to start with as part of a transition, but sometime in your life you should read it.
