Pope Leo’s new encyclical on artificial intelligence invites us to ask what makes human beings truly human. On Trinity Sunday, we remember that we are made in the image of the Triune God, which means we are made not for isolation or mere efficiency, but for communion, love, and relationship. Technology can serve this vocation when it strengthens human connection, but it becomes dangerous when it weakens our capacity to love and be present to one another.

This past Monday, something happened in Rome that you do not see every day. There was a special press conference, and Pope Leo was there speaking. Beside him was the co-founder of Anthropic, one of the major new artificial intelligence companies. You may have seen some of the footage, because at this press conference Pope Leo presented a new encyclical, a teaching document from the pope, on artificial intelligence.
The document is called Magnifica Humanitas, on safeguarding the human person in the time of artificial intelligence. We have known for a while that this document was coming. Pope Leo chose the name Leo because he wanted to stand in continuity with Pope Leo XIII, who is often seen as one of the great founders of modern Catholic social teaching. In Catholic social teaching, the Church looks at what is happening in the world, at new events and new technologies, and asks: how are we called to respond in the light of the Gospel, in a way that promotes human dignity?
Pope Leo has thought a great deal about artificial intelligence. As he said at the press conference, he has listened to many different people: those involved in producing artificial intelligence, computer scientists, engineers, parents, government leaders, people who have lost their jobs, and people who are struggling in various ways. This new document is a response to artificial intelligence, but Pope Leo does not say that AI is simply bad or that we should avoid it altogether. It is a tool, and he sees many good and positive possibilities in it.
At the same time, Pope Leo also describes some real risks. AI can be used in warfare, including unmanned drones, expanding the scope and scale of destruction. It can replace human workers. It can increase our dependence on technology, and even contribute to addiction. It can shape the way we think, the way we relate, and the way we see ourselves.
But most importantly, Pope Leo says that artificial intelligence invites us to ask a much deeper question: what does it mean to be human?
That is really the question at the heart of the document. The very title says it all: Magnifica Humanitas, the magnificence, the greatness, the goodness of humanity. What makes humanity good? What makes us different from artificial intelligence? Pope Leo does not say that human beings are different from AI simply because we are smarter. Rather, he points us back to how we have been created.
Each and every human being, rich or poor, young or old, healthy or sick, powerful or weak, is created in the image and likeness of God. This is what we read in the Book of Genesis. This is what distinguishes us not only from artificial intelligence, but from every other part of creation. We have been created in the image and likeness of God.
But what does that mean?
Does it mean that if we are created in God’s image, we all look like those old paintings of God with a white beard? Does it mean that we somehow physically resemble God? Of course not. This Sunday gives us a beautiful opportunity to remember what it truly means to be created in the image and likeness of God, because today we celebrate the mystery of the Trinity.
If we want to understand what it means to be created in God’s image, we need to understand something about the Trinity. We need to understand who God is, and how this shapes who we are called to be.
Belief in the Trinity is a great mystery, and it took time for the Church to express this belief clearly. Even when we look at Sacred Scripture, we do not find the word “Trinity” written there. The Church came to understand this mystery gradually, through the revelation of Jesus Christ.
For the Jewish people, the most important belief was that God is one. In Deuteronomy 6, we hear the great prayer of Israel: “Hear, O Israel: the Lord is our God, the Lord alone.” There is one God. And yet Jesus presents himself as the Son of God, sharing in the very life of God. He speaks of the Father. He speaks of the Holy Spirit. And so the Church had to ponder this great mystery: how can God be one, and yet Father, Son, and Holy Spirit?
Over time, especially through the great councils of Nicaea in 325 and Constantinople in 381, the Church came to express this faith more clearly. Every Sunday, when we profess the Creed, we profess faith in one God in three persons: Father, Son, and Holy Spirit. Equal in dignity. Equal in divinity. One God, three persons.
But if we leave the Trinity there, it can seem abstract, almost like a complicated theological puzzle. We might think, “That is beautiful, Father, but what does it have to do with my life?”
It has everything to do with our life.
Because the Trinity tells us that God is not isolated. God is not lonely. God is not a solitary individual cut off from others. From all eternity, God is communion. God is relationship. God is love. The Father loves the Son. The Son is beloved by the Father. The Holy Spirit is the love between them.
This is central to understanding what it means to be made in the image and likeness of God. We are made in the image of the Trinity. We are made for relationship. We are made for communion. We are made to love and to be loved.
We are not most fully human when we are independent, isolated, or self-contained. We are most fully human when we live in relationships of love, when we care for others, when we allow ourselves to be cared for, when we serve, forgive, listen, and give ourselves in love.
This is what makes humanity magnificent. This is what makes humanity great. We image the Trinity when we live in communion with others.
For this reason, we need to guard against anything that damages our capacity to live in relationship. And this is where Pope Leo’s reflections on artificial intelligence become so important.
Technology can help us live in closer relationship with others. We all know this. Think about how easy it is now to stay in touch with people around the world. Years ago, international phone calls were expensive and difficult. Now we pick up our phone, open WhatsApp, and speak face to face with someone on the other side of the world. That is a real gift. Technology can help families remain connected. It can help us communicate, learn, organize, and support one another.
But technology can also become a danger when it weakens our relationships instead of strengthening them. Pope Leo warns about dependence on technology, and we can see this clearly in our own lives. Social media promises to make us more social, but sometimes it makes us less capable of real friendship. It keeps us staring at screens instead of speaking to the person in front of us. Algorithms shape what we see, what we desire, what we fear, and what we compare ourselves to. We see carefully edited versions of other people’s lives and begin to think our own lives are not good enough.
Technology can connect us, but it can also isolate us. It can help us communicate, but it can also make us less present. It can serve communion, but it can also damage communion.
So on this great feast of the Blessed Trinity, we are invited to remember who God is and who we are. God is Father, Son, and Holy Spirit. God is communion. God is love. And we are made in the image and likeness of this God.
This means that our choices matter. The way we use technology matters. The way we speak to one another matters. The way we spend our time matters. The way we treat our families, our friends, our parish community, and even strangers matters.
A simple question can guide us: does this choice help me love others more? Does it help me live in deeper communion? Does it make me more present, more generous, more attentive, more human?
Or does it isolate me? Does it make me more distracted, more self-centred, more anxious, more closed in on myself?
The more we live like the Trinity, the more joyful and fulfilled we become. We were not made for isolation. We were made for love. We were made for communion. We were made to image the Blessed Trinity in our lives.
Let us pray for the gift of the Holy Spirit, that we may become more and more what we were created to be: people made in the image and likeness of God, people who reveal the love of the Father, the Son, and the Holy Spirit through lives of communion, service, and love.
