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.

Also called Philastrius and Filaster, a Spanish bishop. He took as his primary mission resisting the spread of the Arian heresy, once enduring a vicious scourging at their hands. Appointed bishop of Brescia, Italy, he continued to oppose the Arians. He authored the work Catalogue of Heresies, an accounting of twenty eight Jewish and one hundred twenty eight Christian heresies, which was a popular book in the Western Church and was used by St. Augustine. He was much praised by his successor, St. Gaudentius.
