"Until the end of the Middle Ages there was no distinction between theology and science. Knowledge was deduced from self-evident principles received from God so science and theology were essentially the same thing"
There is another way of phrasing that...
"Until the end of the Middle Ages, science was constrained by theology. Any discoveries that were contrary to priestly interpretations of scripture were suppressed. Following the Renaissance, and during the enlightenment, a so-called scientific revolution occurred, where more and more science was free to investigate the natural world without being bound by religious perspectives. This is known as secular science, and it has always been controversial among fundamentalist religious groups, for abandoning the Word of God in pursuit of knowledge." Human 14:08, 3 May 2007 (EDT)
