Sermon for Proper 21, Year A
Matthew 21:23–32; Philippians 2:1–13
“Don’t be a Christian.”
That’s probably a bit of a weird thing to hear from your priest on Sunday morning, so I’m going to unpack that a little bit.
Don’t be a Christian. Be Christ.
There is an occupational hazard of my job: it is part of my job to know all of the Christian lingo really well. But the issue is that you can know all of the right Christian lingo, and it still doesn’t change your heart.
It reminds me a little bit of a friend of mine who got really interested in the guitar. So he went online and researched guitars. He bought a book on guitars and read it. He learned all about the history, how they were made, and what the different good guitar companies were.
The only thing he never did was buy a guitar and learn how to play it.
Which kind of defeats the purpose, doesn’t it?
In the same way, there was a philosopher in Denmark in the nineteenth century named Søren Kierkegaard. He lived in a culture that was very nominally Christian. Almost everyone around him considered themselves Christian because, well, they were Danish. Denmark was predominantly a Lutheran country.
Most people were baptized, grew up there, went to church, but there was never necessarily a time within that when a person made a sincere leap of faith, a commitment to becoming a follower of Christ.
And for Kierkegaard, that was an issue.
Jesus encounters a similar process today in our gospel reading.
To set the stage a little bit, this passage that we just read comes immediately after the cleansing of the temple. So this is Holy Week, the last week of Jesus’ life. And Jesus, the day before, had gone in and caused quite a ruckus in the temple and disrupted all the normal proceedings.
The religious authorities are quite understandably disturbed and thinking, We’ve got to regain control of this situation.
So they come up with a plan to trap him. They go up and say, “By what authority are you doing this?” Because they know that he is not one of these students trained in one of their schools.
And they also know that if he claims his own authority, then it’s meaningless. And if he claims God’s authority, then he’s blaspheming.
So there’s no good answer.
They think they’ve got him.
But Jesus, as he usually does, responds to their question by asking another question, telling a story, and then asking another question after that.
So first, the question.
He says, “The baptism of John—by what authority did John baptize?”
And the religious authorities come up with a really brilliant strategic flowchart in that moment.
They think, Okay, here are our two options. If we say it was from heaven, that it was from God, then he’ll say, ‘Why didn’t you believe him?’ And if we say that it was of human origin, then the whole crowd is going to be mad at us because they think John was a prophet.
So there’s not really a good answer for them now.
They opt for the safe answer and say, “We don’t know.”
Jesus says, “Okay.”
And that’s when he starts to tell the story of a man with two sons.
He says to both of them, “Go and work in the vineyard today.”
The first one says, “No, I don’t want to.”
Which is pretty disrespectful. It’s the wrong answer.
But later on, he changes his mind, and he ends up going.
Then the father goes to the second son, and the second son gives the right answer:
“Oh yes, sir. Of course. I’ll go.”
But the problem is, he never actually goes.
And that’s when Jesus comes to the next question that he asks all of them.
He says, “Which of the two did the will of his father?”
Well, obviously, it’s the first one.
It’s not the one who said the right thing. It’s the one who did the right thing.
And that is a disturbing thing for us as religious people, because we’re very good at putting our Christian labels on things.
We can put them up on billboards and on T-shirts. We can put the Ten Commandments on every wall in the country.
But what good is that really going to do if we’re not putting those same commandments in our hearts and following them ourselves as the people who claim to be Christian?
Christianity is more than just branding.
The whole point is to take the words that are in our mouths and let them sink into our hearts, and then move down from there into our hands and feet so that they actually change the way we live in the world.
That’s where the phrase that Paul uses becomes really relevant in the reading that we heard just now.
He says, “Let the same mind be in you that was in Christ Jesus.”
He’s talking about the mind of Christ.
Let the life of Christ become your life.
That same self-giving love. That same refusal to cling to status. That willingness to serve others and show kindness to others.
To be the kind of person that Jesus was—that is the goal.
Not to wear the Christian T-shirts or have the bumper stickers on our cars.
It’s to be like Christ.
“Let the same mind be in you that was in Christ Jesus.”
The one who actually went into the vineyard is the one who did the will of his father, not the one who said he was going to go.
That can raise all kinds of uncomfortable questions for us, because what if there are people around us, in this world and in our community, who do not consider themselves Christians and yet are better Christians than us?
I think particularly of Mahatma Gandhi, who said, “I like your Christ, but I don’t like your Christians. They are so unlike your Christ.”
Gandhi was a man who did not carry the label Christian.
But in so many important ways, he did bear the mind of Christ.
Let the life of Christ become your life.
Go work in the vineyard.
Don’t be a Christian.
Be Christ.
