The Sagrada Familia Basilicaʼs spectacular central spire is crowned by a white cross that makes it the tallest church in the world.

One of the historic milestones of Pope Leo XIV’s visit to Spain was the opportunity to realize Antoni Gaudí’s dream: the inauguration and blessing of the Tower of Jesus Christ, coinciding exactly with the centenary of the great architect’s death.

“God’s architect” died leaving behind a vast legacy of art and devotion visible throughout Barcelona — like an open-air Gospel sculpted in stone.

The spectacular central spire — crowned by a white cross that makes the basilica the tallest in the world and which will be open to visitors starting in 2028 — is undoubtedly one of them.

The celebration marked the conclusion of Leo’s visit to Barcelona before he travels Thursday to two of the Canary Islands — Tenerife and Las Palmas — where the pope will address the suffering of migrants who risk their lives on the Atlantic route in search of a better future.

After Mass, Leo XIV stepped outside to bless and inaugurate the Tower of Jesus Christ — a beautiful ceremony in which the pope, rather than simply putting his stamp on a finished work, charted a course for Christians.

“The Sagrada Família is the tallest church in the world — not to stand out in worldly rankings, but to guide the steps of God’s people journeying through this land of Catalonia, with the cross illuminating the path like a lamp lit in anticipation of the Bridegroom’s return,” he affirmed.

As he has done since setting foot in Spain on Saturday, June 6, the pope delivered a message of unity and harmony.

“The entire city of Barcelona and all of Catalonia gather in this temple — itself a sign of unity and harmony for all of Spain — and lift their gaze to encounter the face of God the Father, resplendent in his son made man, Jesus Christ,” he explained at the altar of the basilica consecrated by Pope Benedict XVI in 2010, noting that it stands as a visible sign of the invisible God.

The pope thus called for eyes to be raised toward the Tower of Jesus Christ and toward that inimitable masterpiece, the Sagrada Família.

Scripture, he said, “teaches us that it is not we who give God a place, as if he were an element in a series or part of a whole greater than himself.”

“Rather, it is God who gives us a place, and the place he gives us is his own heart: the place of the Son, for us who were strangers; the place of the Beloved, for us who are sinners,” he declared.

Like a shepherd guiding his flock in the teachings of the Church, the pope continued his interpretation of the Gospel — specifically, the passage where the Lord tells the Pharisees: “If you do not believe that ‘I AM,’ you will die in your sins.”

“Strong words,” the pope remarked, clarifying “that they are by no means threats or blackmail.”

“They are an invitation to salvation — a call to freedom from Christ, who desires our ultimate, eternal good,” he said. In the face of the threat of evil, “the Lord is always with us, always on our side.”

He then uttered one of the most powerful statements of the trip: “Dear brothers and sisters, we cannot believe in Jesus and promote war. We cannot believe in Jesus and kill the innocent. We cannot believe in Jesus and abandon those who suffer, those who weep, and those fleeing from misery.”

Before celebrating the Eucharist, he went down to the crypt to pray and lay a floral offering where the remains of the architect — whom Pope Francis declared venerable in 2025 — rest. Seeing him pray at the tomb served as further encouragement for the cause of the virtuous life of the architect — who died a century ago on this very day — to eventually be inscribed in the Church’s book of saints.

This was one of the most moving moments, as neither John Paul II nor Benedict XVI visited the tomb during their own visits to the basilica.

The foundation stone of the Sagrada Familia was laid in 1882; for 144 years, it has grown alongside Barcelona — and alongside Gaudí himself, up until the day of his death.

The pope’s presence here represents more than just a tour of a work of breathtaking beauty; it carries an eloquence that transcends its commemorative significance. Few works like the Sagrada Familia so powerfully convey that beauty is not a secondary adornment of faith, but rather a way of making God visible.
