God’s people at The First United Presbyterian Church of Crafton Heights spent the summer of 2025 exploring the transformative event that we call “The Last Supper”. John’s gospel was our guide as we read through John 13-17. On September 28, we completed this study with an exploration of John 17:20-26, which concludes Jesus “High Priestly Prayer” for the church. We also listened to Ephesians 4:1-6.

Have you ever heard of a Rube Goldberg machine? Rube Goldberg was an American cartoonist and engineer of the last century who is best known for his drawings of incredibly complicated gadgets designed to do mundane tasks. When I was a kid, I was enthralled by the game Mousetrap, which brings the Goldberg concept to life.
I learned recently that there is an annual Rube Goldberg contest, which originated amongst the engineers at Purdue University. Recent winners include a 72-step machine that will erase a chalkboard and a 120-step process for feeding a pet.
I bring this up because today we are concluding our series of sermons on the Apostle John’s account of the Last Supper. Jesus and his friends have gathered for dinner. He washes their feet and teaches them for one last time. He spends some time in prayer – for himself, for his disciples, and for people like us who are here because of their faithfulness.
In the Gospel of John, it seems pretty straightforward – a quiet evening with friends, a simple meal, and “love one another as I have loved you.” That doesn’t seem very complicated.
But here we are, 2000 years later, and we’ve got 45,000 different flavors of Christianity on the planet. We are led by popes, pastors, bishops, deacons, abbots, metropolitans, and more. We hold fast to creeds, constitutions, confessions, encyclicals, affirmations, and papal bulls. We meet in sanctuaries, temples, homes, arenas, schools, or online.
Do you think that Jesus saw this coming when he was praying for “those who will believe”? It seems like a lot to go from what could be a couple of dozen folks sitting in a room listening to an itinerant rabbi to trying to imagine the full breadth and depth of the institutional church in all of its forms.
Think, for just a moment, of the vastness of the global church – synods, dioceses, hospitals, universities, convents, congregations, and meeting after meeting after meeting…
What’s it for? And are we doing it right?
As Jesus prays, his focus is on unity. Two weeks ago, he celebrated his unity with God the Father. Last week, he prayed that his friends would be kept together and set apart for some holy purpose. And today, we hear him as he expands his prayer to include us, saying, “that they may be one.” In fact, in verse 23, we see a word we talked about a couple of weeks ago, teleióo, meaning “perfected”, or “finished”, or “complete”. Jesus asks God that somehow, all of these shapes and flavors of discipleship will be brought together with one goal: in verse 22, “so that the world may believe”; in verse 23, “so that the world will know that you have sent me and loved them”; and in verse 26 “so that the love you have for me may be in them.”
It would seem that the fundamental task of the Rube Goldberg machine that is the church in the 21st century (and every other iteration of the church) is to show the love – the agape – the whole-hearted, selfless, unconditional love of God to the world. This prayer is the summation of Jesus’ “farewell discourse”.
In this series of messages, we’ve looked at how John devotes five entire chapters of his gospel to narrating the scene at the Last Supper. There’s the foot washing. The confrontation with Judas. The encouragement he offers. The promises he makes. All of these point to the love, the light, that is in Jesus; all of them prepare Christ’s followers to live the Jesus way in the days to come.
And now, here, in his closing prayer before his arrest and death, Jesus indicates that all that we do, and all that we are, is to be wrapped in that love so that the whole world can see it. The word that Jesus uses there is cosmos, and it means the entire ordered creation is destined to know God’s intentions for love.
So how are we doing?
Are we living into the prayer of Jesus? Is it all about love in the world? How is our part of the Rube Goldberg machine that is the church functioning?
You might point to the monthly food distributions that take place here on the second Friday of every month. Two weeks ago, more than 200 families were blessed by an abundance of dairy, meat, veggies, fruit, and grain. There were no restrictions – no matter what your faith (or lack thereof), your income, your race, your marital status… everybody got food with no strings attached. Yes. That’s love.
Three mornings a week, we’ve got a posse of 3-, 4-, and 5-year-olds upstairs at the Preschool. From what I can tell, there’s not a whole lot of time spent memorizing Bible verses. The kids are working on learning their colors and writing their names. They’re experimenting with tastes and textures. It’s not preachy, but I think we can all agree that training children to wonder, to celebrate, and to be curious is a fine way of equipping them to discover the presence of God in the world.
Last Sunday night, we played a remarkably stupid game at Youth Group called “Beak Wars”. Each of us put some tape on our noses, and then we tried to use that tape to steal the tape off the noses of our neighbors. It was ridiculous!
Can I tell you that the point of that game is not to end up with eight feet of useless masking tape, but rather to create an environment where we are all willing to look silly, to learn to laugh together, and to create a safe space where pain and fear can be shared, and where joy and celebration and friendship can be nurtured? And do you know that all of those things are rooted in and lead to love?
A couple of days ago I met with a craftsman whose great-grandfather was on the team that installed these stained-glass windows 108 years ago. Is there anything connecting the idea of Divine love for the world and our maintenance of these bits of colored glass? Yes – if it’s part of our strategy to create a beautiful and sacred space that is set aside to help form us in our identity as beloved and commissioned by Jesus.
My deep hope and expectation as your pastor is that if you see anything in this congregation that is disconnected from the command of Jesus to “love one another as I have loved you”, that you will call us out on that. How does doing this, or not doing that, allow us to live faithfully the love of Jesus in the systems of this world?
But it has to be more than just here at church, beloved. Jesus is lord of all the earth, not just the guy in charge of an hour on Sunday mornings. The prayer here in John 17 is for the entire cosmos – all of the created order – not just those things that we can label as somehow “religious”.
We cannot seek to create that beloved community in our worship space, our youth group, or our preschool if we are fully comfortable ignoring the children of God whom we see on the sidewalks or on the news.
We cannot hold onto the gift that Jesus gave us back in chapter 14 – “peace I leave with you, my peace I give to you…”, and then go out and vote for war or celebrate the obliteration of a people.
We can say we are for love all day long, but if our actions, our conversations, our social media posts, and the ways that we treat out neighbors are disconnected from that love, what good are we?
How is the love of Jesus being revealed in our pursuit and ordering of a civil society? In our participation in the cosmos?
Look, I’m not naïve. Are we always going to agree on strategies about how to do this? Hardly. If the twelve folks who spent 24/7/365 with Jesus didn’t always share an agenda of action items, then I’m willing to think that we won’t, either. I think we can expect that there will be days when you favor that candidate and those programs while I see it differently.
Our unity does not consist of the fact that we all think alike, look alike, sound alike, shop alike, or vote alike. No, our unity is based in something more fundamental: that we belong to Christ. And the Jesus whom we follow longs to send us into the world as people who will love as he loved us.
I believe that the call of the Gospel this morning is for each of us to take our lives and to look for ways to live out God’s intentions of love in and for the world in every single facet of them – our work, our play, our rest, our relationships. We are called to discover ways to show the compassion of Jesus in the world in each sphere of our lives.
As we do that, we’ve got to remember that it’s not an individual effort: the church that bears Jesus’ name is called to be perpetually reflective of the presence of the Holy in the world and in our neighbors.
Beloved, can we acknowledge and even celebrate differences while rejecting division? Can we disagree on strategy even while remaining committed to the goal?
Take just a moment to have one last look around John 13 – 17. Remember the Lord who washed the feet of those whom he loved, and who reached out with encouragement even to the one who would betray him. Hear him as he begs us to stay faithful, to live in hope, to trust the spirit, and above all, to walk all day, every day, in love. Let us pledge ourselves to doing these things as we move through our neighborhoods, our schools, our workplaces, and our homes. And may we always remember, and be grateful for, the fact that we are held in this together by the love of Jesus. Thanks be to God who makes us one May that unity look more and more like the love of Jesus each day. Amen.






















In this corner, we have Tileman Heshusius. He’s a professor of preaching at Heidelberg University and is also the preacher at the local church. Heshusius is a staunch Lutheran – one of the most important aspects of theology, in his mind, is what one believes happens during the Lord’s Supper. He believed, taught, and preached that the actual body and blood of Jesus was present in the sacrament. Anything else, thought Heshusius, was nonsense.
But what to do? How to get the kids to pay attention to religion, and learn the faith? Frederick had just the ticket: he went out and hired Zacharias Ursinus, age 28, to be the professor of preaching at the university, and a 26 year old named Caspar Olivianus to be the preacher at the local church. I’m not sure whether these young whippersnappers had goatees, or played the guitar, or know all the right slang words, but I do know that Frederick asked them to come up with a means by which young people might be instructed in the path of Christian discipleship. Moreover, Frederick asked them to do it in such a way as to bring people together, rather than driving them further apart.
It is, first of all, deeply personal. This is not a sweeping series of broad theological statements requiring intellectual assent, but rather a string of heartfelt questions addressed to the individual. For instance, this is how the catechism begins:
Too often, the Christian faith is presented as a caricature. God is depicted as a grumpy old man who is really mad at you because you’re such a miserable sinner. Maybe you grew up in a church that defined faithful living as all the stuff we’re not supposed to do: no swearing, no lying, no cheating, no dancing, no card playing… In some churches, the message seems to be this: If you want to make God happy, then straighten up and fly right, Buster. Stop doing all that stuff that ticks God off, and then maybe God will have mercy on your pathetic little soul…
Now, the Gospels don’t record that Jesus ever had to deal with a posse of “mean girls”, but there was a group who consistently targeted and criticized him for being “not like us”. They looked at Jesus and they scolded and mocked him, saying, “What’s up with those losers you surround yourself with? And how can you justify spending your time in that way? And that stuff that you eat? And the people you eat it with? For crying out loud, Jesus, you are embarrassing us. You are so out of it. How dare you think of yourself as one of us, Jesus.”

In my previous post, I wrote about the joys of learning from someone younger than me. When I’d finished Rachel Held Evans’ 

I suspect that I am not the only person in the room who is guilty of having watched a television program called “Mystery Science Theater 3000”. This show ran on Comedy Central from 1988-1999 and was revived on Netflix last year. What you need to know about that program this morning is that it featured a human and several robotic companions watching B-grade movies in an empty theater; the movie would be shown in its entirety and the characters, visible in silhouette on the bottom of the screen, would provide humorous or sarcastic commentary while the film played. Some days, it was pretty funny.
And then something happens – there’s a slight shift. In my mind, it’s like we are watching a drama unfold over Jesus’ shoulder. We are hearing his commentary on the story of worship that day – the religious figures who are leading worship as well as the poor people who take part in other ways. And just as the writers of Mystery Science Theater 3000 hoped, this program of Jesus’ commentary on worship was a smash hit. We read in verse 37 that “the large crowd listened to him with delight.” Everybody was having a good time.
When she thinks that no one is looking, she drops everything she has into the basket. Her offering consists of two coins that are called leptons– which means literally “a thin one”. It was the smallest coin known to that culture, and it would buy about one slice of bread.
Because I am not the only one who longs for respect and affirmation. I may be the only person wearing a white dress and a stole this morning, but each and every one of us in the room this morning knows something about how it feels to simply lovewalking around claiming that there is something external that defines us, that makes us important, that gives us status or prestige or respectability.
