We ask you, urgently: don’t scroll past this

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.

Image of Bl. Ceslaus

Blessed Ceslaus was the son of a noble Silesian family and possibly St. Hyacinth's brother. Hee was ordained, became a canon in Cracow, Poland, a provost at St. Mary's in Sandomir, went to Rome, and was received into the Dominicans by St. Dominic. Blessed Ceslaus preached in Poland, Silesia, Pomerania, and Bohemia, was spiritual adviser to St. Hedwig, was elected provincial of the Polish province, and became prior of a priory at Breslau. His prayers were credited for the defeat of Tartans attacking Breslau in Silesia during their invasion of 1240. His cult was confirmed in 1713. His feast day is July 17.
