Not quite, I think you are using 'faith' to mean knowing 'God's Truth;' they are two different things. I'll try to explain below.
I don't think that it's pointless, nor too extreme of views to use the disciplines of epistemological for the study of God's revelations. I think our disagreement is in what the science is being used for.
I think I better explain here. There are differences in the definitions of faith and truth they aren't necessarily one in the same thing. We're starting to throw around words that seem to have different definitions for the two of us. As best I can understand, I'll parrot St. Thomas (short version).
Faith is a grace, a Divine efficacious gift most always requiring cooperation of the human will to work within the intellect. Virtuous faith proceeds to the virtue of hope, which is the desire of things not possessed or not yet wholly realized. Hope in its turn proceeds to a virtuous charity and love of God, and by extension the neighbor. "Faith is the substance of things to be hoped for, the evidence of things that appear not… By faith we understand that the world was framed by the word of God: that from invisible things visible things might be made.“ (Heb 11:1-3)
Divine TRUTH on the other hand is God's will. We can unequivocally state that God=Truth and such a Truth is absolute and immutable. So, to know a certain Divine truth in Christ's time is to know the same truth today. However, what can change is the full importance of that truth. Explaining it another way, if as in science we say that God's truth is axiomatic, then that axiom remains immutable, but various different corollaries can be deduced. In this way Catholic dogmatic truth remain alive in faith. You might say that the revealed truth shines a Divine intellectual light on life; the truth is in the light, the science is in the 'particulars' of the revealed object.
O soul pressed down by the corruptible body, and weighed down by earthly thoughts, many and various; behold and see, if thou canst, that God is truth. For it is written that "God is light;" not in such way as these eyes see, but in such way as the heart sees, when it is said, He is truth [reality]. St. Augustine, On the Trinity, 8,2
Consequently, I view all the sciences of philosophy, including the discipline of epistemology, as a tool of the intellect in the process of internalizing faith in a comprehensive body of knowledge; which of course produces hope, and charity. By the way, this process works backwards too, by giving charity; we can produce hope, which in turn looks to receive faith. Thus, in being charitable to a child by teaching knowledge of God produces a hope that looks to a faith which proceeds baptism, or any of the other sacramental graces.
Considering the above, I would argue that St. Thomas and St. Anselm used two different intellectual tools internalizing or arriving at a logical understanding (knowledge) of the same cosmological Truths revealed by God.
