The Body of Christ is Irreducibly Complex

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.

Weeds are Good for You

Are there people in the church, either in your own church, another local church, or somewhere in the global church, that seem a bit un-Christian?  Perhaps their doctrine is different than yours, or perhaps they behave differently.  Maybe they dress differently or have different standards in music.  They could have different political beliefs.  It could be anything.

Within a parable Jesus told in Matthew 13:24-30 is some wisdom about “those people.”  The parable is:

He put another parable before them, saying, “The kingdom of heaven may be compared to a man who sowed good seed in his field, but while his men were sleeping, his enemy came and sowed weeds among the wheat and went away. So when the plants came up and bore grain, then the weeds appeared also.  And the servants of the master of the house came and said to him, ‘Master, did you not sow good seed in your field? How then does it have weeds?’  He said to them, ‘An enemy has done this.’ So the servants said to him, ‘Then do you want us to go and gather them?’  But he said, ‘No, lest in gathering the weeds you root up the wheat along with them.  Let both grow together until the harvest, and at harvest time I will tell the reapers, “Gather the weeds first and bind them in bundles to be burned, but gather the wheat into my barn.”’”

For this post, the key phrase in the parable is “No, lest in gathering the weeds you root up the wheat along with them.”  The wheat in the parable represents God’s people, and the weeds represent unbelievers in the midst of them.  The servants ask the master whether they should pull up all the weeds immediately, which seems like a sensible thing to do.  Weeds are bad for crops, right?

The surprising response is that the servants should “Let both grow together until the harvest.”  Why?  Because in the master’s judgment it is better for the wheat if the weeds are allowed to grow.  In other words, removing the weeds before the harvest – when God will separate the wheat from the weeds – would be bad for the wheat harvest.  Until the harvest, the master warns that we could “root up the wheat along with them.”

In Matthew 25 where Jesus tells of the final judgment in verses 31-46, it’s strongly implied that some of the “wheat” will be surprised about being wheat and some “weeds” will be surprised about being weeds.  In verses 37-39 Christians say: “Lord, when did we see you hungry and feed you, or thirsty and give you drink?  And when did we see you a stranger and welcome you, or naked and clothe you?  And when did we see you sick or in prison and visit you?”  In verse 44, unbelievers say: “Lord, when did we see you hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to you?

Therefore, if the wheat and the weeds themselves can be unsure which they are, how can anyone else definitively decide who doesn’t belong, especially to risk damaging those who do belong.  There will always be true and false believers in churches until Christ returns, so remember: According to the Master, the wheat is better off with the weeds than without.  Especially if sometimes what we think are weeds actually aren’t.

When Our Seeds Only Grow Thorns

Sometimes we feel like we’re putting in a lot of effort but getting no results from it.  We’re sowing good seeds but not reaping any harvest.  At times, it seems disappointment is our only reward.  Often this can just be the way things are at the time – we’re doing nothing wrong but it’s just not obvious what God is doing at that time.  We don’t need to change anything.  But there may be times where we’re not reaping good things because we’re deceived that what we’re sowing is what we’re supposed to be sowing.

According to the prophet Jeremiah, the nation of Judah had this problem and as a result they ended up in exile.  In the first half of Jeremiah 12:13, the prophet says of Judah:

They have sown wheat and have reaped thorns;
            they have tired themselves out but profit nothing.

The nation of Judah thought they were sowing good seeds, but they weren’t and there are several examples in Jeremiah’s book.

First, Judah thought they were on the right side politically, with powerful friends and therefore secure.

The nation of Judah allied itself alternately with Egypt and Assyria, who they thought could protect them from Babylon.  Surely these powerful nations could keep Judah from doom at Babylon’s hands.  However, in Jeremiah 3:36 the prophet says:

How much you go about,
            changing your way!
You shall be put to shame by Egypt
            as you were put to shame by Assyria.

Because Judah had trusted these nations, other than God, for their salvation God would put them to shame by His own hand, from which there is no escape.  While there are many good ways to work with others, we should never trust anyone with the help that only God can provide.

Next, Judah thought they had the right cultural heritage.

The people of Judah wouldn’t listen to Jeremiah’s prophesies of doom for the nation because they thought God wouldn’t destroy what they saw as His own nation.  Israel had been taken into captivity by Assyria, but Judah thought it could never happen to them because they were the heirs of Jewish culture.  The people would repeat the phrase, “This is the temple of the LORD, the temple of the LORD, the temple of the LORD,” to remind themselves that they were special because they had the temple, but Jeremiah says in Jeremiah 7:4,

Do not trust in these deceptive words: ‘This is the temple of the LORD, the temple of the LORD, the temple of the LORD.’

The temple was provided as a way to approach God, but Judah thought of it like a magical talisman that would keep God happy so they could do their own thing.  However, God doesn’t want us to follow a checklist – He wants us.  All cultural and political institutions – including ones provided by God – are useless outside of God’s purpose for them.  What He provides He can take away if we abuse it.  When Judah was taken into captivity by Babylon, the temple was torn down and burned.

Last, Judah thought they had the right religion and were diligently practicing it

Judah’s religious leaders and people were diligent in observing the practices laid out in God’s ceremonial law.  They faithfully made the morning and evening sacrifices, observed the three main Jewish festivals, and followed many other ordinances, but in Jeremiah 7:22-23, the prophet said:

For in the day that I brought them out of the land of Egypt, I did not speak to your fathers or command them concerning burnt offerings and sacrifices.  But this command I gave them: ‘Obey my voice, and I will be your God, and you shall be my people. And walk in all the way that I command you, that it may be well with you.’

Because Judah was putting observance above obedience to God, He would therefore discipline them.  The sacrifices were not the objective – the relationship was the objective, but the people made their religion about the sacrifices themselves, not the relationship they were designed to restore.

Do we sometimes practice similar things in the modern church?  Of course we do.

The modern-day equivalent of Judah’s first mistake is when we expect from a political party what only God can give.  Our expectations of them become idolatrous, and we become more likely to compromise God’s principles to support them.  We commit the second mistake when we are convinced our denomination has it all right – the right history, traditions and doctrine – and therefore God will always favor us.  The last mistake happens when we put external religious observances ahead of internal devotion to God.  We may be executing the acts and rituals our religion requires of us, and our peers expect from us, but not giving ourselves fully to God.  We may go to church, but when we leave the church building we don’t take Jesus with us.

Sometimes we think through our political, cultural, and religious activities we should reap wheat, but what is happening when we keep reaping thorns?  Sometimes we need to check that we aren’t repeating Judah’s mistakes.

They have sown wheat and have reaped thorns;
            they have tired themselves out but profit nothing.
They shall be ashamed of their harvests
            because of the fierce anger of the LORD.

Zap! The Best Action Figures for Christmas

Dear fellow travelers,

A hot Christmas gift when I was a kid were G.I. Joe toys.  These “Real American Heroes” were a line of action figures, vehicles and other accessories that fought against the evil Cobra organization which was trying to take over the world (of course).  In 1982, they were even hotter, after Hasbro added “Swivel Arm Battle Grip” to the design to differentiate G.I. Joe from the also-popular Star Wars figures.

Zap looks much better in action than in the box.

The swivel in the middle of the figure’s bicep allowed 360-degree rotation.  The swivel isn’t a shoulder, elbow, or hand, but without it, bazooka soldier (Code Name: Zap) can’t pose as modeled on the package pictured here.  I had “Zap” and tried it for myself.  It took some experimentation, but eventually the way the shoulder, swivel, and elbow were made worked together and Zap looked like Zap should look.

Why so much detail about action figures in a Christian blog?  Because the Christian church is described in the Bible as the body of Christ, and in 1 Corinthians 12:14-16, the apostle Paul assures us that, without every single member of the church participating, the body of Christ is incomplete:

For the body does not consist of one member but of many.  If the foot should say, ‘Because I am not a hand, I do not belong to the body,’ that would not make it any less a part of the body.  And if the ear should say, ‘Because I am not an eye, I do not belong to the body,’ that would not make it any less a part of the body.

Like Zap without “Swivel Arm Battle Grip,” the church will not perform as God intended unless all parts of the body participate, but sometimes it’s not clear to each of us what part of the body of Christ we are.  To some of us, others may clearly look like a shoulder, elbow, or hand, but we don’t know our part.  To some of us, others may look like the “hands and feet of Jesus” (to use a common phrase), but people don’t say the same about us.  Remember that Paul says “that would not make it any less a part of the body.”

Today, let’s return to one of this blog’s key verses, Hebrews 10:24, “And let us consider how to stir up one another to love and good works.”  When we don’t clearly know the specifics of our part, maybe we are the “Swivel Arm Battle Grip” – the innovative, new part with a weird name that helps the other parts fit together and work as God intended.  But also, when we do know our part, is the objective any different?

Does Your Church Have an Unclean Spirit?

Jesus and the apostles spent a lot of their time preaching and ministering to Jews in synagogues.  Some of us might think of the synagogue as similar to a modern church, just a place where believers meet, but in the Bible’s synagogues it’s amazing the type of people you’d find among the “believers.”  Mark 1:23-24 gives us such an example:

And immediately there was in their synagogue a man with an unclean spirit. And he cried out, “What have you to do with us, Jesus of Nazareth? Have you come to destroy us? I know who you are—the Holy One of God.”

Here, Mark points out that there are unclean spirits even in the synagogue, perhaps in hiding.  There are probably unclean spirits even in our churches!  Like in our times, Jewish people who did not go to synagogue probably rationalized that by saying the synagogue isn’t perfect, but terribly flawed.  Why associate with those people?  Mark’s gospel was targeted at Gentile readers, who were probably more likely to criticize those in the synagogue than the Jews.  But, Mark then tells us in verses 25 and 26:

But Jesus rebuked him, saying, “Be silent, and come out of him!” And the unclean spirit, convulsing him and crying out with a loud voice, came out of him.”

Who knows how many unclean spirits there were in the synagogue, how long they had been there, and how powerless the Jewish leaders were to do anything about them!  But, if Mark’s Gentile audience knew the synagogue wasn’t perfect, Jesus was saying He has authority and power to make it perfect in ways nobody else could.  Jesus wasn’t trying to draw people to the synagogue, but to Himself!

Coming back to the idea that our churches in some ways are the modern equivalent of synagogues, the world knows there are a lot of bad people going to church, from hypocrites pretending to follow Christ, to people who are just obviously bad.  Jesus, however, knows perfectly who His people are and who are not, but regardless He isn’t trying to draw people to an imperfect church, but to His perfect self!

Every group of people has a mix of good and bad, and possibly even people with “an unclean spirit.”

Therefore, no institution can accurately reflect who Christ is, not even the visible global church, which is made up of a mix of people that can’t be neatly divided into “good” and “bad.”  Everyone there is a sinner in need of forgiveness and salvation.  But Jesus, who cast out the “unclean spirit” in Mark’s gospel, can also cast out all the evil in His people’s hearts to build the one institution that will last forever in eternity.

Jesus, “the Holy One of God,” has come to build a church full of holy people, and He will not fail.  From within and without synagogues and churches with unclean spirits, God will find His people.
