At 20, he became a Jesuit novice and shortly thereafter was exiled because of the Mexican revolution. He traveled to the United States, Spain, Nicaragua and Belgium, where he was ordained in 1925. Father Pro suffered greatly from a severe stomach problem and when, after several operations his health did not improve, in 1926 his superiors allowed him to return to Mexico in spite of the religious persecution in the country.
The churches were closed and priests were in hiding. Father
Pro spent the rest of his life in a secret ministry to the sturdy
Mexican Catholics. In addition to fulfilling their spiritual needs, he
also carried out the works of mercy by assisting the poor of Mexico
City with their temporal needs. He adopted many disguises to carry out
his secret ministry. In all that he did, he remained filled with the
joy of serving Christ, his King, and obedient to his superiors.
On the day of his death, Father Pro forgave his executioners,
kneeling down, he prayed, bravely refused the blindfold, and then
standing up with both hands outstretched he died from a bullet,
proclaiming "Long Live Christ the King!" "Viva Christo Rey!"
The date was November 23, 1927. He was only 36 years old. This
is his Feast Date.
