“The ordinances of washing and anointing are referred to often in the temple as initiatory ordinances… In connection with these ordinances, in the temple, you will be officially clothed in the garment and promised marvelous blessings in connection with it… members who have received their temple ordinances thereafter wear the special garment or underclothing.”

Boyd K. Packer, The Holy Temple (Salt Lake City, UT: Bookcraft, 1982), 35, 17.
