I met a man who makes stained glass for a living. He told me that he has made stained glass for several temples. I was surprised to learn that when the LDS Church builds a temple, the stained glass must have geometric patterns, rather than other artwork. I asked him if he knew why, and he did not know.
I have been in older LDS buildings, and seen stained glass artwork of the First Vision and other scenes from the scriptures or LDS history. Why do you think Church leaders prefer geometric designs in the temple to other artwork?
