The Body of Christ is Irreducibly Complex

Todd R Leave a comment

Among the various camps in the debate between creation and evolution is a set of ideas called intelligent design (ID).  A key part of ID is “irreducible complexity,” a term that comes from the book Darwin’s Black Box, by Lehigh professor Michael Behe.[1]

In short, irreducible complexity argues that evolution by chance, without an intelligent designer driving it, is unreasonable because the multiple systems in a complex organism like a human body – circulatory, digestive, endocrine, muscular, respiratory, and so on – are all interdependent on each other.  The circulatory system alone, with the heart pumping blood through an elaborate system of arteries and veins, is difficult to imagine developing by chance occurrence, but a chance evolution of that system alongside all the other parts it is dependent on is even more far-fetched.  All systems evolving together in lockstep without failing is a much more difficult problem to explain scientifically without a Creator.  The circulatory system takes what the respiratory and digestive systems take in and deliver it to the other systems that use it.  Without the other parts, it has no function and cannot survive and further evolve.

However, my intent here is not to prove intelligent design, but to consider the apostle Paul’s words about the church as the body of Christ.  In 1 Corinthians 12:12, he wrote: “For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ.”  He continues that no part of the body can say it is not a part of the body because it has a different function than another part (1 Cor. 12:15-16), and also that no part of the body can say it doesn’t need all of the other parts (1 Cor. 12:21).  Those who are in Christ Jesus cannot be divided.

Paul follows his description of the body with 1 Corinthians 13, a powerful statement on the supremacy of love, and in context a gentle rebuke to the idea that a body can survive as individual, unrelated units.  In a human body, any part can only survive by serving the other parts.  Even an organ as incredibly complex and important as a heart cannot survive if it decided to pump blood only for itself.  Where would it get its nutrients?  How would it flee from danger?  As Paul wrote: “If the whole body were an eye, where would be the sense of hearing? If the whole body were an ear, where would be the sense of smell?” (1 Cor. 12:17).  Even an organ as important as the heart is useless in isolation.  It gets its very life and purpose by what it does for the body.

As Jesus said to His disciples in John 13:34-35 – “A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.  By this all people will know that you are my disciples, if you have love for one another.”

As the song says, they will know we are Christians by our love, and the church Jesus came to build is irreducibly complex.  There is no appendix[2] in the church, which is the body of Christ.  All members are absolutely essential.

Time for a Change 2026 (4 of 9)

Fellow travelers,

Are there small changes you can make to improve your life? Are there small things you are doing that are harmful to you?  Can each of us build a better “liturgy” for our lives over time, step by step? Can we accumulate victories in small battles that help us fight bigger ones?  Over time can we better love God, ourselves, and others?

Instead of making New Year’s resolutions or celebrating Lent, every 40 days I try to make a small, permanent change in my life habits.  I keep a list of the changes I’ve made or want to make.  This is all voluntary, so I don’t criticize myself for missing a deadline or going back on something.  If I fail at some of the changes, the successful ones still add up to a massive shift over time.  I don’t always do “spiritual” changes, just something small I think will make my life better, permanently.  For example, one of my goals from 2021 was to drink at least 32 oz of water a day, and I still do it (with an occasional miss).

I’ll be making a small change, and if you want to participate, tomorrow, May 1st, is 120 days after the start of the New Year and time for the next change.  If you do, keep a record of what you’re changing.  As the months and years pass, hopefully the cumulative change becomes enormous. The next date on the schedule (40 days later) is 6/10/26, and I have a couple of things under consideration for then.  I’ll be posting a reminder at about that time; if you want to participate, start making a list of things you might want to do more or less of, and let’s see what we can accomplish!  This habit of changing habits has been helpful to me and might be to you, even if you have your own way of doing it.

Loveless Words

“If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal.” – 1 Corinthians 13:1

The church in 1st-century Corinth was divided over spiritual gifts, particularly the gift of speaking in tongues.  The apostle Paul wrote 1 Corinthians 13 as a gentle rebuke to the misuse of gifts and the arrogance that came from competing over them.  The first verse above could be paraphrased as “you can be speaking the most impressive-sounding things, but if you’re not saying it to benefit those who hear, you’re just making noise.”

But not just any noise – Paul purposefully chose two specific instruments.  In a symphony, an appropriately timed cymbal or gong has a glorious impact that perhaps no other instrument can match.  However, although you might not catch one bad note from a clarinet, you won’t miss a gong or cymbal played at the wrong time, even once!  To God, the only one with a truly perfect ear, that’s what loveless words sound like.

“If even lifeless instruments, such as the flute or the harp, do not give distinct notes, how will anyone know what is played?” – 1 Corinthians 14:7

Render to God

Todd R Leave a comment

The phrase “render to Caesar the things that are Caesar’s, and to God the things that are God’s” which Jesus spoke in Luke 20:25 is likely a familiar one.  I had a friend in college who worked at Little Caesar’s pizza, and he showed up at Bible study with some pizza from there one night.  We had agreed to split the cost, so when he walked in he said “render unto Caesar!”  We all got the reference and a couple of us laughed (I admit one of them was me).

The “render to Caesar” saying comes from a time where some scribes and chief priests tried to get Jesus in trouble, as they often did, trying any means necessary to condemn Him.  In this case, they first flattered Jesus, trying to catch Him off-guard, then asked Him, “Is it lawful for us to give tribute to Caesar, or not?”  They thought if Jesus said yes, it would upset the Jews who wanted their Messiah to overthrow Rome, and that if He said no, it would upset the Romans and perhaps they would arrest Jesus as a revolutionary.  They thought they had Him trapped, but His answer quoted above was unexpected by them, yet truthful and insightful.

Often the lessons taken from this story have to do with Jesus’ ability to thwart the attempts of His enemies to catch Him in His words, or with the Christian’s obligation to pay taxes, or with something about the relationship between the Jews and Rome.  There are several good applications.

Another important application that’s key to the story, can be highlighted if we shorten the saying to “render…to God the things that are God’s.”  This last part of the quote is where Jesus subtly tells those trying to catch Him that they weren’t giving to God the things they should be.  Although they were the religious leaders of their day, they were focused on the wrong things, like their money and their resentment against the government.  Or even their obsession with arguing with Jesus.

What are the things that are God’s and that we should render to Him?

Paul helps answer this in Romans 12:1, which says “I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.”

Here Paul says that the thing we should be rendering to God is our very selves, and Jesus implied this when He said “render…to God the things that are God’s.”  This answer said to the Jews, and everyone listening, that their Messiah wasn’t only going to overthrow Rome, but He was going to overthrow all kingdoms, including those we build in our own hearts and minds.  From an eternal perspective, the many flaws of Roman rule under which the first-century Jews lived were minor inconveniences, including the paying of taxes and other, real abuses.  Jesus wants us to focus on the real challenge: what to do about mankind’s rebellion from God?  This is the real mission of the Messiah.

Luke follows the “render to Caesar” story with a question some Sadducees asked Jesus about the resurrection, also to try and catch Him saying something wrong.  The story was not put there by accident, but in the sequence, I think we see that there is in fact a resurrection, and that our resurrected selves will be much different than our current selves.  Our new selves will be able to perfectly worship God, and we will be able to fully offer our “bodies as a living sacrifice” while we can only do so imperfectly now.

In the meantime, we don’t get a free pass to do what we want because we aren’t perfected yet.  Every day and every moment, we are to “render…to God the things that are God’s” in ways the religious leaders of Jesus’ day (as well as the audience of most of the Old Testament prophets) failed to do.

In closing, I’ll quote the OT prophet Micah, who differentiated between the animal sacrifices of ancient Israel from the “living sacrifice” God requires:

“With what shall I come before the LORD,
            and bow myself before God on high?
Shall I come before him with burnt offerings,
            with calves a year old?
Will the LORD be pleased with thousands of rams,
            with ten thousands of rivers of oil?
Shall I give my firstborn for my transgression,
            the fruit of my body for the sin of my soul?”
He has told you, O man, what is good;
            and what does the LORD require of you
but to do justice, and to love kindness,
            and to walk humbly with your God?”  (Micah 6:6-8)

Today, “render…to God the things that are God’s.”

The Work of Our Hands

Todd R Leave a comment

Psalm 90 is the only one out of 150 that was written by Moses.  Psalm 90 is also the first in book 4 of the Psalms, which some say carries many of the themes and ideas from the 4th book of the Pentateuch, the book of Numbers.  That book tells of the consequences of Israel’s disobedience and grumbling on their journey to the Promised Land.  The nation of Israel spent 40 years wandering, seemingly aimlessly, in the wilderness and only Joshua and Caleb from the prior generation actually entered the Promised Land.

As noted in a recent post, the Psalm begins by saying we are only home when we are with God, but the Psalm ends with this petition to God for us:

“Let your work be shown to your servants,
            and your glorious power to their children.
Let the favor of the Lord our God be upon us,
            and establish the work of our hands upon us;
            yes, establish the work of our hands!”

It may seem easy, or even natural, to just go with the flow of our surrounding cultures while in this world, but that would really be like wandering in the wilderness instead of getting God’s promised blessing.  Instead, do we seek that God’s “work be shown to your servants,” and that He “establish the work of our hands upon us”?  Do we seek “the favor of the Lord,” and experience His “glorious power”?  This is what Moses asks for in this prayer, that we find our purpose in Him by doing His work.  We all have “worldly” responsibilities we need to take care of in this world, but none of them are the ultimate goal.

In other words, the best way to spend our short lives here is to do work that matters in eternity, which God has laid out for us to do:

“For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.” – Ephesians 2:10
“So teach us to number our days
            that we may get a heart of wisdom.” – Moses, in Psalm 90:12
