By Dominican Friars Thomistic Institute · Published by TAN Books This edition emphasizes fidelity to Catholic tradition, a disciplined approach to prayer, and growth in the theological and moral virtues. It provides practical guidance suitable for a home, parish group, or classroom, encouraging slow reading, reflection, and concrete resolutions. The aim is steady conversion, not quick impressions, so the structure helps readers remain focused on Scripture, the sacramental life, and the wisdom of trusted Catholic teachers. 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 doors. Proceed at a deliberate pace, keep notes, and return to passages that move your conscience. Formation takes time, and the fruit shows up in family life, apostolate, and faithful service in the parish. Prayer Book The Credo Prayer Book is a companion piece to the program and has been compiled to introduce catechumens and candidates to the wealth of Catholic devotional prayers. It offers a representative sampling of the most common vocal prayers said by Catholics. While it was originally composed for new Catholics, it can certainly be used by any Catholic to assist and nurture one’s prayer life. Catechist Guide 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. This complete and customizable 36 session program works with any level of current OCIA engagement. Use it as a supplement or make it the core of your OCIA. Following the prayers, a brief compendium of various important lists and other information can be found, such as the Ten Commandments, the Beatitudes, the Precepts of the Church, and others. Video Access The Credo Video Series, produced in collaboration with the Dominican Friars and the Thomistic Institute, features 72 professionally filmed lessons—two per session across 36 topics—that bring the foundations of the Catholic Faith to life. Each 12-minute segment combines clear doctrinal teaching, theological depth, and real-world witness from converts and clergy. Perfect for group study or personal formation, these videos guide catechumens step by step through the truths of the Creed, the sacraments, and the moral life of the Church—all available to watch free of charge.
