Jeff Cavins is recognized both nationally and internationally as one of the most effective and engaging speakers in the Church today. Few can communicate their love for Jesus Christ with as much zeal, clarity, and enthusiasm as Jeff Cavins. In addition to his outstanding presentations related to Catholic Bible study, Jeff is available to speak on a variety of other faith-formation topics.

After twelve years as a Protestant pastor, Jeff returned to the Catholic Church under the guidance of Bishop Paul Dudley. His conversion story, one of the best known and most inspiring stories of its kind, is chronicled in the best-selling book, My Life on the Rock. After his conversion, Jeff received an MA in Theology from the Franciscan University of Steubenville.

Over the past several decades, Jeff has dedicated his life to developing The Bible TimelineⓇ: The Story of Salvation, a practical, interactive program that helps people read the “big picture” of God’s plan of salvation in Sacred Scripture and understand its meaning for their lives.

For 2025, The Bible Timeline has been refreshed with new videos filmed on location in the Holy Land, Greece, Rome and several other locations, and new presenters such as Fr. Mike Schmitz, Mary Healy, and Dr. Marcellino D’Ambrosio. The Great Adventure Bible Timeline presents the entire sweep of the Bible in a way that is easy to understand and genuinely fun to engage. As the foundational element of The Great Adventure Learning System, the Bible Timeline has revolutionized Catholic Bible Study for hundreds of thousands of Catholics.
