Bacon abandoned biblical prophecy to read Islam through philosophy

Evidence

The first and most important difference is that, whereas earlier thinkers had seen Islam as a religion with only a negative role in history as a falling away from the truth, a preparation for the final holocaust of Antichrist, part of a downward movement, Bacon (and he is not the only man of his time to see this) had some conception of an upward movement toward unity and articulateness in which Islam had an essential role to play before it withered away. He entirely abandoned the Bible as an instrument for understanding the role of Islam in the world, and relied exclusively on philosophy. — R. W. Southern, Western Views of Islam in the Middle…, 352
