Grand Canyon Urantia Society, or GCS (officially Grand Canyon Society for Readers of The Urantia Book) is a group of Arizona Urantia Book readers and is a local chapter of The Urantia Book Fellowship. It is the purpose of GCS to devote its energies to making The Urantia Book known and available to all.

At the heart of GCS is a network of longtime friendships and personal relationships that have lasted more than thirty years. For this purpose, we periodically gather together for fellowship and various social events. Regular local Urantia Book study groups also foster group interaction and dialogue for both new and longtime readers. We welcome and encourage new friends—members and non-members alike—to join us for many of our events.

Society membership offers the opportunity to participate in an organized approach to the principles and teachers of The Urantia Book. The society encourages its members to express their commitment to The Urantia Book at a degree beyond the study group level by creating more opportunities for spiritual fellowship, service, and growth.

One of the unique aspects of our Society is the commonality of our goals while fostering individual expression. As such, individual members and friends of GCS have developed or promoted related projects that GCS encourages and supports when possible. Since our formation, we have hosted local and regional workshops, retreats, and conferences, as well as booths at local Expos and Urantia Book introductions at various locations in the Phoenix Valley.
