Faith and Epistemology
How do we know anything for certain? What you think you know— could it be wrong? Sure. Our brains and sensory equipment are not perfect. So why do we have so much faith in them? Human beings have a need to “see it to believe it”, a tendency to trust in their own senses. But our senses can be mistaken and our interpretations of what we see and hear can be way off the mark.
Epistemology is about how we know anything, and whether our knowledge is trustworthy and reliable as “truth.” It is the investigation of what it is that distinguishes justified belief from mere opinion. Where religious faith is concerned, we have an inherent problem. If our beliefs were so self-evident that virtually everyone would have to agree, then we would not call it “faith,” it would be universally accepted as certain knowledge (like our belief in gravity). Faith is about believing when the evidence to our senses is not overwhelming. It is more about personal trust (in a person, in a testimony) than about intellectual or scientific belief.
"Faith is being sure of what we hope for and certain of what we do not see."
(Hebrews 10:39-11:1)
After the Resurrection, Jesus said to Thomas: "Because you have seen me, you have believed; blessed are those who have not seen and yet have believed" (John 20:29). Some people insist upon proofs from God, or personal visions, or overwhelming experiences in order to develop and maintain their faith. That is why people are attracted to miracles and relics and the like. There does appear to be a fine line between receiving positive signs and visions that help the doubting Thomases and depending too much upon such signs.
While there are objective aspects to faith (more for some people than for others), religious belief and faith is so personal, subjective, and experiential that it is virtually impossible to transfer this knowledge to another person unless they trust your judgment and are truly openminded. So our testimony online has severe limitations… what we say we “know” will not be accepted as true knowledge by others unless perhaps they already agree to these kinds of claims.
On the primacy of faith: “It is not a case of proving first and then believing. We cannot believe theological truths for non-theological reasons. Rather, it is only when we encounter the living God in faith that we are in a position to grasp the truth of Christian faith. God then enables us to see with spiritual eyes what we could not previously see. The spirit is able to understand what the mind of the flesh is unable to conceive.” (Dr. Colin Brown, from "Philosophy and the Christian Faith”) And without spiritual help (from God of course) people will just not get it. How do you get such spiritual help? You ask for it, of course; you have to mean it, honestly praying for spiritual insight.
