I found the link to this on another blog as I caught up on my Google Reader this morning. The Saint's Name Generator will select a saint for you, and provide you with a description of his/her life and causes. I used it to select a saint for my blog for the upcoming year. You say a prayer as the generator works, and then click to find your new patron.
St. Mary of Egypt originally worked as a prostitute for many years, until one day she tried to enter a church and found that she physically couldn't open the doors. She underwent a dramatic conversion and asked Our Lady for her guidance. She heard a voice tell her to cross the Jordan River, and from that point forward she lived as a hermit in the desert until her death 50 years later. She is the patron of penitent women and sexual temptation.
