In 2017, Rod of Iron Ministries splintered from the Unification Church, a Korean cult founded by Sean Moon’s father, Sun Myung Moon. Adherents are called Moonies and believe that Sun Myung Moon is the messiah. Two of Sun Myung Moon’s sons, Sean and Kook-jin, or Justin, founded Rod of Iron Ministries. The church has many of the same core beliefs as the Unification Church—but it claims that AR-15s are the “rod of iron” that Jesus wields in the Book of Revelation. Perhaps not coincidentally, Justin Moon founded Kahr Arms, a firearms manufacturer that produces a commemorative Donald Trump AR-15.
