Patronage
"Because the honor of God is highly concerned in your intended undertaking, I took some time to recommend it to Him by my poor prayers."
A Valencia Dominican with a raucous voice and famously poor memory, Louis Bertrand sailed to Colombia in 1562 and reportedly baptized over 30,000 people in seven years — preaching in Spanish while, per his canonization document, being understood in every native tongue. He returned to Spain not as a colonial hero but as a defender of those he had served, dying quietly in Valencia on the feast day the Church would one day assign him.

Letter on Apostolic Undertakings
A letter in which Bertrand counseled a correspondent planning a great work for God's honor — urging them to ground every enterprise in prayer before acting, a distillation of his missionary spirituality.
O holy Louis Bertrand, Apostle of the Americas, who crossed the ocean with only the Gospel and returned bearing thirty thousand souls — intercede for us. You who preached in Spanish and were heard in every tongue, teach us to speak the truth of God in ways every heart can receive. You who buried the plague dead with your own hands and defended the conquered peoples of the New World, give us courage to stand beside those whom the world has discarded. Patron of Colombia, of novices, of all who carry the Gospel into unknown lands — Saint Louis Bertrand, pray for us. Amen.

Life Journey
Early Life
Born in Valencia on January 1, 1526, and related to Saint Vincent Ferrer, Bertrand entered the Dominicans at eighteen against his father's will, ordained in 1547 by Archbishop Thomas of Villanova.
Turning Point
In 1562, he sailed to Cartagena, Colombia — within seven years baptizing thousands across Panama, Tubará, and Santa Marta, his Spanish sermons miraculously understood in native tongues.
Legacy
He returned to Spain in 1569 to defend indigenous peoples, continued as preacher and novice master in Valencia, and died October 9, 1581 — his own future feast day.
