　　 Luis Segura Vilchís stood before the firing squad. Beside him lay the body of Father Miguel Pro. He was a member of the Mexican Catholic Youth Association and also part of the armed resistance of the National Federation for the Defense of Religious Freedom in the capital. On November 23, 1927, he was immediately shot alongside his father and brother, along with Juan Antonio Tirao, an accomplice in the Obregon assassination, at the site of the current National Lottery Building.

　　Father Miguel Agustín Pro was a Jesuit priest martyred by firing squad in Mexico in 1927. With his arms spread in the shape of a cross and declaring “Viva Cristo,” bullets tore through his chest. He was executed by firing squad to restore religious freedom in Mexico, where all worship was banned by the anti-religious government. 

　　During President Obregón's term, conflicts began between Catholics and supporters of the Mexican Revolution. Some bishops actively campaigned against land reform and the organization of workers into secular unions. Obregón was elected President of Mexico in 1920, inheriting a chaotic nation. His presidency focused on stabilizing the country, implementing the 1917 Constitution, and promoting economic and social reforms.

　　The Legitimacy of Christian Warfare: In the 12th century, Saint Bernard of France taught Christians the legitimacy of war against pagans. In war, dying for Christ or killing is not a crime but an honor. Death in battle leaves no trace of sin and brings glorious merit. Christ accepts the enemy's death as punishment and offers Himself to the soldier as consolation. Dying in war is for oneself, while killing is for Christ. It is the act of God's messenger punishing evil and exalting good. When Christians kill the wicked, they are not committing murder but slaying the devil. When Christians themselves are killed, they are not perishing but attaining eternal glory. The death a Christian gives is again for Christ's sake; the death he receives is for his own benefit. Christians rejoice at the death of pagans, for Christ receives glory; in the death of Christians, generosity is shown. It is better for them to be killed, so that the righteous do not yield to the injustice of their hands.
