The mind is able to comprehend God to a fair degree. Wesley’s quadrilateral of Scripture, tradition, experience, and reason is a helpful guide in comprehending God. Scripture itself is revelation of God in that it is God-breathed; as one scholar put it, “to grasp God’s revelation is to grasp God himself” (TDNT). Tradition connects the modern person to the church of the past, and all sorts of people who have gotten their own grasp of God through the areas of the quadrilateral. Experience is an avenue through which God is revealed. Finally, reason implies that truth exists and it is possible to seek such truth. These four areas in themselves do not establish that the mind can comprehend God to any degree, but establish that the mind is able to comprehend God.
Taking just two of the four—Scripture and reason—I will reflect on the extent of the mind’s ability to grasp God. Scripture is communicated using one of the most basic units of communication: words—specifically, words about God. These words are neither equivocal (without direct correspondence to what the words describe) nor univocal (a direct correspondence); rather, they are analogous and express truth in a manner that is accurate but does not give the full picture. Many truths and experiences are conveyed through the words of Scripture, and because the mind can comprehend these words to a fair extent, the mind can comprehend God to a fair extent.
Reason provides a means for one to think more deeply about God and his revelation. Because reason can allow one to think fairly clearly on many issues, one can expect the same when applying reason to God, Scripture, and experience. Reason can only go so far, but at the very least, the mind can think fairly well on the various ways God has been manifested to this world.
