Saint Mateo Correa Magallanes was a priest and a Knight of Columbus. During the persecution of the Church in Mexico in 1927, he had a choice to make.
He was in the jails hearing confessions from prisoners rounded up by the government. Now, a general was pressing a gun to his head, threatening to kill him if he did not disclose what prisoners had told him in confession.
Mateo said, “You can do that, but just know that a priest must keep the seal of confession. I am willing to die.” Shortly after that, he was taken to the outskirts of town and killed.
Every priest takes his obligations as a confessor seriously.
