Someone recently said to me (and I have heard this sentiment many times before, even said it myself)...
the idea is to see cultural issues through the lens of Biblical Truth. We do not look at scripture through the lens of contemporary culture.
And I guess my response to that would be: we need to prayerfully, carefully, rationally strive to see God's Way through the lens of Jesus' teachings and a correct understanding of the Bible and rational consideration of circumstances, but the caution would be that we don't allow our interpretation of the Bible to conflate with God's Way.
It seems to me that when we say, "we need to see culture through the lens of Biblical truth," it is IMPLICIT that what we MEAN is, "...through the lens of Biblical truth AS I UNDERSTAND IT..." and paying attention to that is key to good, rational, humble Bible study.
IF "Biblical Truth" (AS WE UNDERSTAND IT) becomes, to us, simply "What God says...," then we run the risk of conflating OUR UNDERSTANDING of Biblical Truth (which, again, is what we are actually saying when we reference Biblical Truth) with God's Word. We wouldn't put it this way, but it makes us out to be a little god and places us in the wrong position - the position of speaking for God what WE BELIEVE, as if God were speaking it.
So, for me, I'm not trying to discern cultural issues through MY INTERPRETATION of the Bible, rather, I'm striving to discern cultural issues through God's Will, which is my goal. The Goal, then, is not "what the Bible says," but rather, "God's Will."
The Bible (which I have to reason my way through), my reason, real world evidence, God's Spirit, God's Word writ upon my heart... these ALL can contribute to my better understanding God's will, but they ALL depend on my own good reasoning, and that includes MY UNDERSTANDING of the Bible.
And this is a concern precisely because I am a flawed and imperfect human being. I am entirely capable of being mistaken and misunderstanding points. This is true when I'm having a face-to-face conversation with a normal person in my own language and in my own culture, how much MOREso would it have to be true of an infinite God, the Great Mystery, so perfect, so wonderful as to beyond my own understanding - a God who does NOT speak to me (or any of us) audibly and directly?
"Now, we see as through a glass, darkly," Paul tells us. And this is a hugely important point. It makes the difference, IT SEEMS TO ME, between being able to hold opinions with grace, good humor and good judgment and holding opinions with arrogance and poor judgment.
My concern is that people read a passage, find a verse they like and say, "The Bible says it and I believe it, that settles it..." without taking into consideration that it is THEIR UNDERSTANDING of the Bible that they are referencing, not "the Bible" magically telling them what to believe.
After all, I read Genesis 1 and can easily easily say, "The Bible says it, I believe it, that settles it!" and mean it entirely. The Bible DOES contain a creation story and I DO believe God is the Creator, but that does not mean that I should take what appears to be written in clearly mythic language as a literal history, any more than I should take passages written in clearly poetic language as literal commands.
Now, having said all of that, I would add that I don't find the Bible, for the most part, to be that hard to understand. I think its teachings are generally consistent, reasonable, understandable and pretty danged obvious (if challenging and hard to live up to, short of God's grace). I don't find the Bible to be a puzzle in the least.
But here's the thing: This is true, probably, for most people who disagree with me, too.
I'm just suggesting that it would be a bit arrogant to say that I - and those who agree with me - are the Ones with the ONE TRUE understanding of God's Will.
This would seem to me to be a clear, rational, obvious Biblical (and logical) Truth.
