Ronald Numbers grew up as the son of a fundamentalist Seventh-day Adventist minister, attending Adventist schools and being taught young-earth creationism until adulthood, where he lost his faith and became an agnostic. Today he is perhaps the world's leading scholar on the history of the relationship between science and religion.
If you were to ask Professor Numbers for the “greatest myth” about the historical relationship between science and religion, he would respond that it's the idea the the two “have been in a state of constant conflict.”
Timothy Larsen, a Christian historian who specializes in the nineteenth century, agrees: “The so-called ‘war' between faith and learning, specifically between orthodox Christian theology and science, was manufactured . . . . It is a construct that was created for polemical purposes.”
