The Light of the World is an oratorio composed in 1873 by Arthur Sullivan. Sullivan wrote the libretto with the assistance of George Grove, based on the New Testament. The work was inspired by William Holman Hunt's popular 1853–54 painting, The Light of the World. The story of the oratorio follows the whole life of Christ, told mostly in the first person, focusing on his deeds on Earth as preacher, healer and prophet.
The work was first performed at the Birmingham Festival on 27 August 1873 and was the composer's second oratorio, the first being The Prodigal Son (1869).
