Each year, pastors and catechists face the challenge of welcoming new Catholics into the Church, yet few resources are available to help them introduce the Faith in a comprehensive way.




The Dominican Friars and the Thomistic Institute in Washington, D.C. developed this groundbreaking RCIA video program that carefully teaches catechumens the key tenets of the Faith. The accompanying guide book walks candidates through the course, introduces them to the treasures of the Catholic faith, and is a valuable reference during their formation and beyond.

Credo includes sessions for Mystagogy, the often neglected period of discovery after catechumens are received into the Church. Plus, powerful interviews from recent converts allow catechumens to hear from their brothers and sisters who have already completed their journey through the Church’s door.

This complete and customizable program works with any level of current RCIA engagement. Use it as a supplement or make it the core of your RCIA.
