The Memorial of St. Martin de Porres is held on November 3.
He was born in Lima in Peru, the illegitimate son of a Spanish nobleman and a black ex-slave. His mother gave him a Christian education and he became a pharmacist and a nurse. Despite his father’s opposition he entered the Dominican Order as a lay brother in 1603 and spent his life working for the sick and the poor. Many people of all ranks would come to him for advice. He had a great devotion to the Holy Eucharist. He has been named as a patron saint of those of mixed race. –Universalis
