Bono at least seems familiar with C.S. Lewis’ Mere Christianity:
I am trying here to prevent anyone saying the
really foolish thing that people often say about Him:
‘I’m ready to accept Jesus as a great moral teacher, but
I don’t accept His claim to be God.’ That is the one
thing we must not say. A man who was merely a man and
said the sort of things Jesus said would not be a great
moral teacher. He would be either a lunatic–on a level
with the man who says he is a poached egg–or else he
would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God: or else a
madman or something worse. You can shut Him up for a
fool, you can spit at Him and kill Him as a demon; or you
can fall at His feet and call Him Lord and God. But let
us not come with any patronising nonsense about His being
a great human teacher. He has not left that open to us.
He did not intend to. (pp40-41)
