Bono’s work as an activist, which is due largely to his Christian beliefs, began in earnest when, inspired by Live Aid, he travelled to Ethiopia to work in a feeding camp with his wife Alison and the charity World Vision, an Evangelical Christian humanitarian aid, development, and advocacy organisation.
With regard to Bono’s 2013 declarations in interviews published and videotaped of his faith in Jesus Christ, he states that Christ was either who he said he was, or he is “a complete and utter nut case”. As early as 2005, Bono was invoking this argument, identified as the “Lewis trilemma”. Bono’s variant of the trilemma stemmed from the theological outline C.S. Lewis is well-known to have used to prove the divinity of Jesus.
