His full name is Juan Martin de Porres Velasquez, St. Martin de Porres was raised in poverty and suffered from the stigmas of being mixed race and of being born as an illegitimate child. Despite these trials, he was known for his kindness and charity.
He learned bloodletting and administering medicines when he was studying with a barber-surgeon. At the age of 15, he volunteered in helping care for the sick in the Dominican monastery infirmary. He was compassionate to everyone, giving alms to the poor, and even extended his love to animals.
He was also known for ministering to the African slaves being brought to the city. He even raised money for the dowries of poor girls so they can marry. He is the patron saint of social justice, racial harmony, and mixed-race people.
