After reading the Book of Mormon for years, do you realize the words, Urim and Thummim are nowhere to be found? The word used in the Book of Mormon is “Interpreters.”
Interpreters
Why is that important?
Because when you hear someone mention “Urim and Thummim” you need to know if they are talking about the original Interpreters of the Book of Mormon, or about some other item not including the actual Interpreters. Remember “A” or “The”
Single Stone or the Interpreters?

President Nelson’s Video
Speaking about the method of Translation President Russell M. Nelson said, in that video, at the 3:30 mark the following: “Quite miraculous really, we have through the gift and power of God, we have a lot of suggestions about how it was done…” President Nelson also in this video demonstrated with a hat in his hand and spoke about the possible use of, as he said, “Urim and Thummim Seer Stones” as he is quoted as saying in the video titled. “The Book of Mormon Is Tangible Evidence of the Restoration. (Link Here) https://www.churchofjesuschrist.org/media/video/2020-05-0290-the-book-of-mormon-is-tangible-evidence-of-the-restoration?lang=eng&collectionId=9e790dc7ca744028bf6f1e1e4676fd60
The method of Translation is not a question about doctrine but about belief or opinion.
“Fairly recently, a great number of the Church Historians, Professors and other intellectual people feel strongly that Joseph Smith used a single stone in a hat, and the words that Joseph saw on the stone would appear, and he would then tell his scribe those words, and they would write it down. These many Historians use the words of Martin Harris and David Whitmer who said that Joseph did use a single stone in a hat in this way. Of course, many people in the Church including the Prophet may use the information and research which the Church Historians have come up with in talks and to help us understand things. I don’t mind the help from these loyal Historians who work to help us. It is when these Historians begin depending on second and third hand witnesses and they then promote them as facts. That is what I don’t like. Why would a Historian use the secondhand quote from David Whitmer, when there were many firsthand quotes from Joseph and Oliver and actual scripture in regard to the method of translation?” Jonathan Neville
The Brethren don’t often concern themselves with nonessential information. Doctrine and special witness of the Savior is most important to them, and it should be. Our wonderful Prophet and Apostles depend on historians and other quorums to research and answer historical questions, as they trust them as I do, to share accurate information.

No one except Joseph, Oliver and Lucy Mack Smith (Under a Linen) have ever seen the breastplate or the spectacles, so researchers could only share what their interpretation is of the information they have found. Many historians rarely look outside the box and there is always a hat or a rock nearby, so that makes it easy to demonstrate. Many historians also like to come up with new theories. Our Prophet is just re-sharing many things the historians have shared with him. That’s why the Brethren rarely say exactly how the translation happened as it is not revelation, so it really doesn’t concern them. I suppose it shouldn’t matter to most of us, as the spiritual confirmation that Joseph used the gift and power of God is the best answer. However, I enjoy searching for additional answers as Moroni said, “ye may know the truth of all things.”
The stone in the hat is not a fact but many historians and Church videos show it as the “New Narrative”, which they seem to enjoy being at the forefront of supposedly new information. Read about a possible narrative below. Could the historians have said Joseph used a hat and not actually putting the stone in it? Could be.
