In addition to Roman Catholic and Orthodox Christian uses,[3] the symbol also appears in the seal of the Church of Christ, Scientist, where it is surrounded by the words "Heal the Sick, Cleanse the Lepers, Raise the Dead, Cast Out Demons", from the Gospel of Matthew, 10:8.
The cross and crown symbol is often surrounded by the phrase "In Hoc Signo Vinces", which is Latin for "By this sign thou shalt conquer".
This is a reference to the story of Constantine, who reportedly had a vision of a Chi Rho symbol, and a voice saying "By this sign thou shalt conquer".
First appearing on the cover of the January 1881 issue of Zion's Watch Tower,[10] the cross and crown were surrounded by a wreath of laurel leaves, and the symbol was also used on lapel pins, buttons (metal and celluloid) and pendants of various designs.
Bach's cantata Weinen, Klagen, Sorgen, Zagen, BWV 12 (1714) contains an aria "Kreuz und Krone sind verbunden, Kampf und Kleinod sind vereint" ("cross and crown are bound together, conflict and jewel are united")[14] which has been connected with Luther's rendering of 1 Corinthians 9:24-25.
