“George Buttrick… was [from 1927 to 1954] pastor of the Madison Avenue Presbyterian Church in New York. One week he had been off on a speaking engagement and was flying back to New York City. On the plane he had a pad and a pencil and he was making some notes for next Sunday’s sermon. The man seated next to him was eyeing him with curiosity. Finally, the curiosity got the best of him, and so he said to Buttrick, ‘I hate to disturb you—you’re obviously working hard on something—but what in the world are you working on?’ “‘Oh, I’m a Presbyterian minister,’ said Buttrick. ‘I’m working on my sermon for Sunday.’ “‘Oh, religion,’ said the man. ‘I don’t like to get all caught up in the in’s and out’s and complexities of religion. I like to keep it simple. “Do unto others as you would have them do unto you.” The Golden Rule, that’s my religion.’ “‘I see,’ said Buttrick. ‘And what do you do?’ “‘I’m an astronomer. I teach at the university.’ “‘Oh, yes,’ said Buttrick. ‘Astronomy—I don’t like to get all caught up in the in’s and out’s and complexities of astronomy. Twinkle, twinkle little star, that’s my astronomy.’” Quoted from Bill Turpie in Dever, Mark; Graeme Goldsworthy (2006-04-10). The Message of The Old Testament (p. 940).
