Saint Catherine of Siena was born on March 25, 1347, in Siena, Italy. She joined the Third Order of St. Dominic but still lived at home. St. Catherine was humble and always helped those in need. When she was 21, she had a vision from Christ which is known as her "mystical marriage to Christ" in which she received a ring only visible to her. The Lord told St. Catherine to reenter public life and help the poor and sick. She continued to serve the needy and got involved in politics, petitioning for peace. She established a monastery for women and later became a Doctor of the Church. 

St. Catherine died on April 29, 1380, due to an illness. 

Her feast day is also celebrated on April 29, and she is the patron saint of the United States, Italy, miscarriages, people ridiculed for their faith, sexual temptation, nurses, and against fire and illness.
