This past two weeks the Church’s calendar has been full of celebrations reflecting on what we in the church call the “Communion of Saints”.
Last Saturday, All Saints’ Day, we celebrated the Church Triumphant—those who’ve made it home to heaven.
On Sunday, All Souls’ Day, we remembered the Church Suffering—souls being purified in God’s mercy.
And that leaves us, the Church Militant, the Church still on Earth, still fighting the good fight right here.
Three days… one Church—heaven, purgatory, and earth all connected. And that means when we gather for Mass, we’re not alone; the saints, the souls in Purgatory, and us sinners are all part of this great Communion of Saints.
It’s why today’s feast fits perfectly. It’s the Dedication of St. John Lateran Basilica – a feast day for a building, which sounds unusual. But it’s a reminder the Church is both heavenly and earthly—divine and human—all part of one big, grace-filled, sometimes messy family.
In case you didn’t know, the Basilica of St. John Lateran is a church in Rome. Now, a lot of people think St. Peter’s at the Vatican is the Pope’s church.
But technically, it’s St. John Lateran—the “Mother and Head of all Churches in the City and the World”, as the inscription on the outside facade of the Church reads.
That’s the Cathedral church of the Bishop of Rome, the Pope. It’s where popes lived for centuries, before St. Peter’s was built.
Built after Christianity was legalized around 324, it was the first place believers could worship in public.
No more hiding in catacombs or whispering hymns underground. The Church could finally come out of hiding to pray and worship out loud.
But this feast isn’t really about marble and mosaics. It’s about what that building represents: the living Church Jesus founded—and the living temples we’re called to be.
The first reading gives us a vivid picture: Ezekiel sees a temple with water flowing from its side, running down through the desert, bringing life wherever it goes. It turns salty seas fresh. Trees spring up whose leaves never wither.
That river is grace—God’s life flowing from His dwelling place into a thirsty world. And that’s what the Church is supposed to be: a source of life, not a museum of memories.
In the Gospel, Jesus walks into the Temple and finds the money changers turning worship into business.
He flips a few tables and makes His point: “Stop making my Father’s house a marketplace.” Then He adds, “Destroy this temple, and in three days I’ll raise it up.” They thought He meant the physical building—but He meant Himself.
He’s the true Temple. And in St. Paul’s words, that same presence now lives in us: “Do you not know you are the temple of God, and the Spirit of God dwells in you?”
That means every baptized Christian is a walking tabernacle of God’s presence. And every time we receive the Eucharist, that presence is renewed—Christ Himself dwells within us.
But the Church isn’t just spiritual — she’s also visible and ordered. From the very beginning, the Church has been united in three ways: leadership, liturgy, and belief.
We can look at the Acts of the Apostles and the writings of the early Christians and see evidence of this:
There were bishops — shepherds appointed to guide the flock in unity with Peter and the apostles. That’s the leadership.
There were sacraments — baptism, Eucharist, confession, anointing — celebrated with the same grace and purpose we know today. That’s the liturgy.
And there was a creed — a common profession of faith every believer could stand and proclaim together. That’s the belief.
THAT’S what keeps our Church one, holy, catholic, and apostolic. They’re like the banks of Ezekiel’s river: without them, the water would scatter and dry up.
This is what theologians call ecclesiology — the study of what the Church is and why it matters. It’s not an abstract idea; it’s the heart of who we are as Catholics. The Church isn’t something we invented — she’s something Christ founded.
The early Church Fathers understood this deeply. St. Cyprian of Carthage wrote in the third century, “You cannot have God for your Father if you do not have the Church for your Mother.”
It was true then, and it’s true now. The Church isn’t merely the structure we gather in — it’s the Body of Christ giving birth to faith, nourishing it through the sacraments, and guarding it in truth.
Without our bishops, our sacraments, and our creed like in other denominations, we can see the devastating results.
Leadership becomes whomever’s personal interpretation you agree with. Liturgy becomes entertainment. Beliefs become personal opinions.
But with them, the life of God keeps flowing strong and clear, generation after generation.
But some folks we know today would rather go to the Church of Me. You’ve met that congregation. The creed goes something like: “I believe in God, but I sleep in on Sundays. I worship on my porch with coffee. I don’t need all those rules.”
Now, there’s nothing wrong about porches or coffee — but Jesus didn’t say, “Where one person gathered in My name, there I am.” He said, “Where two or three are gathered.”
Honestly, the “Church of Me” can be very tempting. It’s convenient. It’s comfortable.
The homilies are always short, I pick my own hymns from the playlist on my phone, and the pastor never tells me I’m doing something wrong — because I’m the pastor!
But that’s not the Church Jesus founded and the differences are huge.
The Church of Me never gets in my way. The Church of Jesus challenges me.
The Church of Me changes with the wind. The Church of Jesus stands on rock.
The Church of Me avoids suffering and the cross. The Church of Jesus carries it to resurrection.
When we unite ourselves with Christ in the Eucharist in Jesus’ church, He dwells within us. The same God who made the waters of Ezekiel’s vision flow now flows through us.
And just like Ezekiel’s river gave life to the desert, after Communion, we should bring life to the world around us through our words, our mercy, our forgiveness.
So the question this feast puts before us is simple but serious:
Which Church are you following — the Church of Jesus, or the Church of Me?
One worships comfort, the other carries the cross.
One dries up in pride; the other flows and gives life.
One fades with the world; the other stands forever.
Today, as we honor the Lateran Basilica—the first great church where believers could worship freely—let’s rededicate not just buildings, but also our hearts. Let’s ask Christ to cleanse our temples, to sweep away whatever keeps grace from flowing freely.
Because the Church isn’t just in Rome. It’s right here. But most importantly, it’s in our hearts.
And in the end, there’s only one Church that leads to eternal life—
and it’s not the Church of Me. It’s the Church of Jesus Christ.
