Dear readers, Catholic Online was de-platformed by Shopify for our pro-life beliefs. They shut down our Catholic Online, Catholic Online School, Prayer Candles, and Catholic Online Learning Resources essential faith tools serving over 1.4 million students and millions of families worldwide. Our founders, now in their 70's, just gave their entire life savings to protect this mission. But fewer than 2% of readers donate. If everyone gave just $5, the cost of a coffee, we could rebuild stronger and keep Catholic education free for all. Stand with us in faith. Thank you.Help Now >

Roman martyrs, twin brothers and deacons. From a distinguished family, they lived in Rome with their wives and children. Arrested, the brothers refused to sacrifice to the Roman gods and were arrested. They converted their guards and escaped but were soon recaptured. Both died in Rome. Their basilica in the catacombs of St. Balbina was discovered in 1902. Their cult was confined to local calendars in 1969.
