Millions of people turn to Catholic Online for prayers, Daily Readings, saints, Catholic education and answers about their Faith. Most will never donate. But if Catholic Online has given you more than $5 worth of value this year, we're asking you to do something very simple: Give $5 today.

Your Catholic Voice Foundation also supports Catholic Online School, which has served 2.2 million student enrollments in 193 countries. We don't believe a family's ability to pay should determine whether a child can receive a Catholic education. If we've given you something of value, please give something back.

Image of Sylvester III

Probably not legitimately a pope, Giovanni di Sabina ascended to the papal throne as the third Sylvester in 1045, when the Crescenti drove Benedict IX from Rome. After a month and a half, Benedict returned to Rome and ousted Sylvester. When Benedict sold his title to John Gratian, Sylvester returned to Sabina. The council at Sutri charged him with obtaining the see of Rome by simony but suspended his sentence. Sylvester died c. 1063.
