The thirteenth century was one of the most theologically vibrant periods in the history of the Christian church. It was in this period that the subject matter of theology was more closely defined, and that theology became a subject for study in educational institutions. One of the features of the Renaissance was urban life, which experienced a growth and popularity it had not known since the Roman era. By 1200, anyone who aspired to the best education in theology made their way to Paris. Under Aristotelian influence, it was easy to produce theologies that were pantheistic or subsumed incorporeal individuals into a single undivided intelligence. As Christian theologians grew more knowledgeable of Jewish biblical interpretation, commentators from that tradition, especially Maimonides and Rashi, were quoted with admiration, and even given preference over some Christian readings of texts. Over time, philosophical theology was confined to an increasingly narrow academic ghetto, and science and rationality moved to conquer the world.
