An execution device became the most loved symbol in human history. Here is what Catholics believe happened on Calvary, and why the Cross changed everything.
Crucifixion was designed to humiliate. The Romans reserved it for the lowest criminals and rebellious slaves, and they left the bodies on display so passers-by would get the message. No serious religion in the ancient world would build its centre of gravity around such an image. Yet within three centuries the Cross was the symbol of the Roman Empire. Within two thousand years it is the most recognised symbol in human history. Catholics do not venerate it as a reminder of a tragedy. They venerate it as the pivot on which the whole of history turned.
The Catechism is direct: The first man not only lost the grace with which he had been endowed; he also lost the holiness and justice in which he had been constituted (CCC 416). The Fall severed something in the relationship between God and humanity. Death entered the world. Sin became the condition of human life, not just a catalogue of individual failures but a wound in the nature of the thing.
What happened on Calvary was the answer to that wound. The Church teaches that three things occurred when Jesus died on the Cross.
On the evening of 8 May 2025, when Pope Leo XIV appeared on the balcony of St Peter's Basilica, the Cross was carried out before him. Bishop Mark Davies wrote a pastoral letter to the Diocese of Shrewsbury that evening. He described what he had seen:
It seemed significant that before we caught sight of our new Pope, we saw first the Cross of Christ carried onto the balcony of Saint Peter's. For the Pope always stands before the world as a witness to Christ and to the victory of His Cross.
That instinct, to look at the Cross first, before anything else, is deep in Catholic life. You see it at the front of every church. You see it in the Sign of the Cross with which Catholics begin every prayer. You see it in the Stations of the Cross walked by millions every Lent. Catholics believe the Cross is an ever-present event: what happened then reaches into the present moment because the one who died on it is alive.
If the Cross is true, three things follow for ordinary life.
You can walk into Shrewsbury Cathedral on any day of the week. The address is Town Walls, Shrewsbury SY1 1UE. The Stations of the Cross are on the walls of the nave: fourteen scenes from Christ's final hours, from his condemnation to his burial. They are meant to be walked, slowly, one at a time. Many parishes across the diocese walk them together on the Fridays of Lent.
The Cross at the front of the Cathedral stands as witness to everything the building exists for. The rubric in the Mass says the priest venerates the altar, which holds relics of saints who died because they would not deny what the Cross means. The Cathedral was built in 1856 by people who had been told, for three centuries, that their faith was illegal. They built it because they believed the Cross had changed everything, and nothing that could be done to them had changed that.
Read Isaiah 53 in the Old Testament: He was pierced for our transgressions, he was crushed for our iniquities (Isaiah 53:5). Then read it alongside the account of the Crucifixion in John 19. Isaiah was written seven centuries before Christ. Ask yourself whether the correspondence is accidental.
Then come to a Good Friday liturgy at your local parish, or at Shrewsbury Cathedral, and stay for the Veneration of the Cross. You will see Catholics come forward one by one and kneel. They are acknowledging what happened there, and who was on it, rather than worshipping a piece of wood.
