When Martin was 12, his mother apprenticed him to a barber-surgeon. He learned how to cut hair and also how to draw blood (a standard medical treatment then), care for wounds, and prepare and administer medicines.
After a few years in this medical apostolate, Martin applied to the Dominicans to be a “lay helper,” not feeling himself worthy to be a religious brother. After nine years, the example of his prayer and penance, charity and humility led the community to request him to make full religious profession. Many of his nights were spent in prayer and penitential practices; his days were filled with nursing the sick and caring for the poor. It was particularly impressive that he treated all people regardless of their color, race or status. He was instrumental in founding an orphanage, took care of slaves brought from Africa and managed the daily alms of the priory with practicality, as well as generosity. He became the procurator for both priory and city, whether it was a matter of “blankets, shirts, candles, candy, miracles or prayers!” When his priory was in debt, he said, “I am only a poor mulatto. Sell me. I am the property of the order. Sell me.”Saint of the Day
