July 5, 2026 | The Catholic Roots of the USA

Welcome to Season 7 of Catholic Review RadioCelebrate America’s 250th anniversary with a fascinating look at the often-overlooked Catholic roots of the nation on Catholic Review Radio. Host Rita Bittner speaks with Dr. Dennis Castillo, professor of Church history at St. Mary’s Seminary, to explore how a small but influential Catholic community helped shape the founding of the United States.

From the remarkable story of Charles Carroll – the only Catholic signer of the Declaration of Independence – to the quest for religious freedom that inspired many Catholics to support independence, this episode uncovers key contributions that defy their minority status at the time. Castillo also highlights the pivotal role of Maryland, early struggles against anti-Catholic laws, and the establishment of the first U.S. diocese in Baltimore under Bishop John Carroll.

The conversation covers surprising moments of Catholic influence, including how missionary leadership in the Midwest helped secure American territory. The podcast offers rich historical insight into faith, freedom, and the fragile beginnings of a nation and a summary of U.S. history, Catholic heritage and the enduring meaning of independence.
