[Temple] We are informed that the rules of the [United States] Navy do not permit its men to wear any other clothing than that provided by the Navy, and it is quite possible, therefore, that our brethren who have received their endowments who join the Navy may not be permitted to wear the temple garment. In that event there would be no wrongdoing on their part in ceasing to wear the garment while serving in the Navy, as it is ceasing to wear the garment from choice that constitutes the wrong. But of course it will be their duty to wear the garment whenever free to do so. [Joseph F. Smith, Anthon H. Lund, and Charles W. Penrose to Hans P. Ipson, June 12, 1917]
