I read while Aquinas obviously believed in the existence and necessity of the Revelation, he nevertheless emphasized the criticalness of Reason [Intellect] in understanding the existence of God.
For example, Aquinas do not accept that God created the Universe in time in 6-7 days but rather he argued from reason that the Universe has no beginning-in-Time nor end which contradict Genesis' creation of the Universe.
Aquinas rejected Medieval Theological Voluntarism;
- Associated with Duns Scotus and William of Ockham[3] (two of the foremost medieval scholastic philosophers), medieval theological voluntarism (not to be confused with meta-ethical theological voluntarism) is generally taken to be the philosophical emphasis on the divine will and human freedom over and above the intellect (voluntas superior intellectu).
For example, Scotus held that morality comes from God's will and choice rather than his intellect or knowledge.
Accordingly, God should be defined as an omnipotent being whose actions should not and cannot be ultimately rationalized and explained through reason.
As such, voluntarism is usually contrasted with intellectualism, championed by the scholastic Thomas Aquinas.

- Medieval theological intellectualism is a doctrine of divine action,
wherein the faculty of intellect precedes, and is superior to, the faculty of the will (voluntas intellectum sequitur).
As such, Intellectualism is contrasted with voluntarism, which proposes the Will as superior to the intellect, and to the emotions; hence, the stance that "according to intellectualism, choices of the Will result from that which the intellect recognizes as good; the will, itself, is determined.
For voluntarism, by contrast, it is the Will which identifies which objects are good, and the Will, itself, is indetermined".[8]
From that philosophical perspective and historical context,
the Spanish Muslim polymath Averroës (1126–1198) in the 12th century,
the Italian Christian theologian Thomas Aquinas (1225–1274), and
the German Christian theologian Meister Eckhart (1260–1327) in the 13th century, are recognised intellectualists.
