What was the relationship between faith and reason in the Middle Ages?
In the “high middle ages” (the thirteenth and fourteenth centuries) two religious orders dominated the realm of scholasticism: franciscans and dominicans. One of the most discussed and heavily debated questions amongst these two religious orders was something contemporary philosophers might call moral psychology or philosophy of mind. The debate was in regards to whether the will or the intellect was dominant in practical reasoning. The Dominicans (to which Aquinas belonged) believed that the intellect was dominate. This meant that in moral deliberation if one truly knew what was right (what was good) then the will would carry said action out. This position is dubbed the “intellectualist” position. The Franciscans were representative, generally, of what is called voluntarism. This view is more or less opposite of the intellectualist position. It holds that the intellect could supply the will with the right option, but that the will could simply refuse to carry out what it knows is good. In other words they observed that sometimes the will is “weak” and doesn’t carry out what it knows it should.
Further, an important aspect of monastic life was education, specifically study of the scriptures, the early church fathers (Patristics) and the classics of the Greco-Roman period. Learning was considered a form of devotion to God and a necessary component of loving God in body, mind, and spirit. In addition it is also known that some convents even engaged in the copying of manuscripts and provided intellectual avenues for learned (albeit aristocratic) women to pursue the scholarly life.
The Creation of the University
As John C. Scott describes, the university in the Western World was a creation of the Middle Ages. The very first institutions for higher learning apart from the monastery were known as cathedral schools, specifically designed by the bishop in major cities to train and educate clergy. As European societies became increasingly complex and new forms of specialized education were in need, the university extended as a natural outgrowth of these cathedral schools. For instance, the University of Paris (est. c.1150) was an extension of the cathedral school at Notre Dame, the cathedral in Paris.However, the University of Paris is not unique in it’s Christian affiliation. Cambridge’s first college was founded by the Bishop of Ely (in the province of Canterbury) in 1284. Oxford too, the oldest university in the English speaking world, is known to have had strong ties with the Dominicans, Franciscans, Augustinians and Carmelites as early as the thirteenth century. So, it would be safe to say that the creation of the modern, western university had its roots in Christendom, particularly the cathedral schools and monastic movements of the Middle Ages. It would be hard to defend an anti-intellectual caricature of religion in light of these realities.
A Cautionary Note on Orthodoxy
All of this is not to say that the medieval university was a place free from any academic restriction whatsoever. Although education featured largely in the Christian world it was most certainly restricted in some significant ways. A major concern of both the Church and its related institutions was the maintenance of orthodoxy (straight teaching in Latin). Certainly scholasticism provided a means for philosophers and theologians to extrapolate on the tradition (and sometimes even explicitly questioning it), but too far of a deviation was no doubt a cause for concern and sometimes scholars were forced to recant their positions or were expelled from the university if found guilty of heresy. The concern appears to be mostly theological on the surface; however, there is significant evidence to suggest that many instances of condemned heresy were more rightly political disputes and controversies. 
Hopefully it has become clear that through investigation into the actual intellectual climate of the Middle Ages that it was a period of intellectual growth and interest, not a period indebted to scholarly barrenness. Monks, scholastic philosophers, and clergymen alike all rendered study as an essential component to growing their faith and devotion to God. Not only was the Bible and the Patristics suitable for study, but also subjects such as logic, grammar, and the classics of the Greco-Roman Period, including Cicero, Plato, Aristotle, and the Stoics. Indeed, there was an obvious synthesis between Christianity and reason that existed during the Medieval period. Reason was thought to shed light on theological questions; it was not viewed as a danger to faith. The dichotomy between faith and reason that many are surely familiar with in today’s political and cultural climate would not be introduced until after the Reformation and grew substantially among fundamentalist reformed movements in America in the seventeenth century.
