St. Joan of Arc
St. Joan of Arc was born in France in 1412. When she was young, France was fighting a civil war and also was trying to stop the English king from taking the French throne.
At age 14, Joan began to hear the voices of St. Michael, St. Catherine and St. Margaret. In 1428, they told her to help the king of France reconquer his kingdom. It took a little while, but Joan convinced the king that she had received a mission from God to help him.
Joan was given soldiers to command, and she won may battles. She was eventually captured and handed over to the English, who burned her at the stake for being a heretic. Many years later, Pope Callistus III reopened her case and found that she was not a heretic.
Joan was canonized in 1920, and we honor her on May 30.
