Before the firing squad did their military duty, Pro forgave them all and shouted the battle cry of the rebellion and profession of faith "Viva Cristo Rey" (or Long live Christ the King).
At the beatification of Miguel Pro in 1988, Pope St. John Paul II proclaimed:
Neither suffering nor serious illness, neither the exhausting ministerial activity, frequently carried out in difficult and dangerous circumstances, could stifle the radiating and contagious joy which he brought to his life for Christ and which nothing could take away. Indeed, the deepest root of self-sacrificing surrender for the lowly was his passionate love for Jesus Christ and his ardent desire to be conformed to him, even unto death
VIVA CRISTO REY!
