For many years, Deacon Charles Joiner faithfully taught catechism at Saint George Greek Orthodox Cathedral in Greenville, South Carolina, guiding inquirers and catechumens into the fullness of the Orthodox Christian faith. Rooted in the living tradition of the Church, his classes were not merely academic but an invitation into a transformative way of life-one shaped by Holy Scripture, the teachings of the Fathers, and the experience of the Orthodox Church through the centuries.

This book is a fruit of those years of instruction, offering a structured yet accessible guide for those seeking to understand and embrace the Orthodox faith. Whether read as an introduction for newcomers or as a deepening of understanding for lifelong Orthodox Christians, it serves as a pathway into the beauty, depth, and spiritual wisdom of the Church's ancient yet ever-relevant teachings.
