St Catherine was an amazing woman. Born during a turbulent period of Church history, she was influential in convincing the Pope to return to Rome from Avignon. Her writings are some of the most influential in the Church and was proclaimed a Doctor of the Church in 1970. She died at the age of 33.
She is buried at Santa Maria supra Minerva in Rome (in the shadows of the Pantheon) and is one of my favorites in the city.
