Viva Cristo Rey!

Father Mateo Correa Magallanes, the Martyr of Confessional Secrecy, in Mexico
Viva Cristo Rey!
In 1927, during the Mexican government’s continuing persecution of the Church, Father Mateo Correa Magallanes was arrested by soldiers as he was bringing Viaticum to an invalid woman.
On 5 February 1927, Father Correa was asked by General Eulogio Ortiz, to hear the confessions of some imprisoned members of the Cristeros, an uprising of Catholic men who decided to fight back against the persecution of the Church led by Mexico's president Plutarco Elias Calles.
Father Correa agreed to administer the Sacrament of Confession to these prisoners, but afterward General Ortiz demanded to know what the condemned prisoners had confessed.
Father Correa refused.
General Ortiz then pointed a gun at Father Correa's head and threatened him with immediate death.
Father Correa continued to refuse, and at dawn on February 6, 1927, he was taken to the cemetery on the outskirts of Durango and shot through the head.
