Proclaimed a Doctor of the Church in 1970, St. Catherine of Siena was a counselor to Pope Gregory XI and Pope Urban VI.
"Work…in the field you see God calling you to work in, and don’t trouble or weary your spirit over what is said to you but carry on courageously. Fear and serve God selflessly, and then don’t be bothered by what people say, except to have compassion on them." —Saint Catherine of Siena
