Albert Einstein looked in his later life for what he called a unified field theory. The search is still ongoing for a “Theory of Everything.” What can unite our knowledge of the universe under a single theory or principle? To encourage the concept, the fields of electricity and magnetism, once thought to be separate are now seen as “electromagnetism.” Apparently the difficulty is in combining general relativity with quantum mechanics. String theory has been advanced, with others as new candidates to become the Theory of Everything.
Leaving theoretical physics aside, the biblical text has a unified theory of everything. One such instance is in Ephesians 1:9,10
Ephesians 1:9-10 ESV
making known to us the mystery of his will, according to his purpose, which he set forth in Christ  as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
The word for “unite” is in Greek, anakephalaioo. This word has the idea of gathering together, or summing up. A speaker might end a long address with a summing up of the main idea. An accountant would add up the numbers in a column, and in Ancient Greece, put the sum at the top of the column.
So the unified theory of life is that “everything in heaven and earth will be summed up in Christ.” A similar usage of the word is found in Romans 13:9 where all the Law is “summed up” or “united” in the command to love:
The commandments, “You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,” and any other commandment, are summed up (anakephalaioo) in this word: “You shall love your neighbor as yourself.”
What does this mean that all things are or will be summed up in Christ? Well here are a few scribbles on that
- The universe is ultimately personal – it is Christ, not a formula that unites and explains all things.
- Jesus is not merely my buddy or personal assistant.
- There is a unifying wisdom or principle to all things, even if theoretical physicists can not come up with one in their field.
- Only God can create this unity, it would appear our attempts will fall short of the mark.
We will be thinking about this for a while, and would value your thoughts.
