Origins

Literally, “light of the world”. From John 8:12 in the Vulgate: “Iterum ergo locutus est eis Jesus, dicens: Ego sum lux mundi: qui sequitur me, non ambulat in tenebris, sed habebit lumen vitae. (“Then Jesus spoke again to the people, saying, “I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.”)
