“Between Heaven and Earth” Videoclips
In 2002 the Church released a documentary on LDS temples that was originally broadcast between sessions of General Conference. It is entitled “Between Heaven and Earth” and is available on VHS or DVD at Deseret Book, Church Distribution, or the BYU Bookstore. It is being shown at temple open houses and in temple preparation classes throughout the Church. The Millennial Star published a post on it back in 2005, with great excerpts. As the Millennial Star points out, it is very possible that Truman Madsen personally made requests of some of the non-LDS scholars to appear and speak on the subject of temples in antiquity and the Mormon practice today. Many of their comments are very insightful to the Latter-day Saints. The scholars/authorities that appear in this film include: Frank Moore Cross (Harvard), Krister Stendahl (Harvard), Lawrence Schiffman (NYU), John Lundquist, Truman Madsen, Elder Boyd K. Packer, and Elder Jeffrey R. Holland, among others.
I think it is an excellent study from many angles, inside the Church and out, of the LDS practice of building and worshiping God in temples. You may see the 44-minute film below:
