"One of the hallmarks of the Catholic tradition with certain conspicuous exceptions, has been to be in dialogue with the philosophy and science of its day and to use such insights in articulating the vision of Catholicism. Such efforts have been done better and worse. Many have taken time to evaluate the correctness or usefulness of particular articulation. But in almost all cases, because of new discoveries in science, changes in scientific theory, and the use of new philosophical frameworks, the insights and articulation of the faith of one generation have differed from those of another. Sometimes such differences have led to severe conflict. One remembers the Copernican revolution, the case of Galileo in the seventeenth century, and the tensions introduced by the rediscovery of Aristotelian science in the thirteen century. Nor can historians of medieval theology forget that that certain philosophical views of Aquinas himself were regarded as theologically dangerous by two successive archbishops of Canterbury and condemned by the bishop of Paris in 1277 on the advice of the prestigious university theological faculty, a condemnation that was lifted insofar as it applied to St. Thomas only two years after the saint’s canonization in the fourteenth century."
