Everything matters.
Yes, it is true that some things matter more than others. Sometimes, when we study something, we devalue certain phenomena in order to get a conclusion. This is part of being human because we are not able to comprehensively account for all knowledge. We will never be able to develop a theory that is based off of a truly comprehensive knowledge. We will never be able to have a truly comprehensive knowledge of a minor discipline. Even if we did, we do not have the capacity to account for every fact in that discipline. Yet we do need to realize that everything matters.
In some sense, this is a theological point. We read in Colossians 1 that not only is everything made through Christ but everything will also find fulfillment in him. Christ himself told his disciples in Matthew 5 that our Heavenly Father clothes the lilies and cares for the sparrow. He knows the hairs on our head. Even though Creation was in six days, God took care of every detail. God continues to watch over every detail in our lives.
When we approach scripture then, having this awareness that everything matters, we should know that every word matters, every turn of phrase matters. There is a reason God is putting all these words together in a certain way. This is more true of Scripture than other books. We should note the little details in Shakespeare but Shakespeare never has the attention to detail that God has. God intends a greater significance in the little things than Shakespeare could have imagined.
(A “trans-hermeneutical principle” is something that applies to interpretation in every area of knowledge. A variety of thinkers have noted that a “hermeneutical point of view” not only interprets texts but is a filter for receiving all knowledge. We are applying the metaphor of hermeneutic to all of life. This does not mean that we have accepted Derrida’s view that everything is text. Rather, this means that we see an analogy to text in everything around us.)
