Joseph Smith preached in the Temple, announcing that a severe judgment awaited those members who had turned "traitors" and were opposing the use of [Kirtland Saftey Society] bank notes. This disobedience, said Smith, "has given power into the hands of the enemy" (non-Mormons who opposed the [Kirtland Saftey Society], etc.) Smith also warned that LDS "covenant breakers" would "feel the wrath of God."
