對於中世紀的哲學能否被合法也稱之為一種「基督教哲學」，歷史上的研究者曾進行過多次的爭論，但至今尚未得出定論。而在這場爭論中，一個最為關鍵首最為棘手的問題就是：這一時期的哲學與基督宗教之間的聯繫是否賦予了它們以積極的內容。從這種角度看問題，我們發現，在中世紀哲學的集大成者多瑪斯．阿奎那的思想體系中，信仰與理性並不是兩種截然不同的思維方式，神學與哲學也不是兩個被無原則地摻和在一起的理論體系，而是兩個相互滲透和相互作用的、有著必然的內在聯繫的構成要素。

　　　　　That whether the medieval philosophy can be reasonably can be reasonable regarded as a kind of「Christian Philosophy」still remains a problem to its researchers. And in their disputes about this problem, the most important and difficult issue is that whether the relation between medieval philosophy and Christianity had produced any positive effects. Viewed from this angle, we find that in the theory of Thomas Aquinas, a representative figure of medieval philosophy, belief and reason are two interrelated and interpenetrated constituent elements, which are connected with each other intrinsically and necessarily, rather than two independent systems that were mixed together occasionally and unnecessarily.
