Sunday School is the teaching arm of the church, running weekly before the main service to give members of all ages a structured, systematic understanding of Scripture. Using the official RCCG Sunday School manual alongside supplementary material, certified teachers lead engaging classes for teens and adults across multiple learning tracks. The department also organizes an annual Sunday School Week, complete with quizzes, recitation contests, and awards, to celebrate diligent study of the Word and encourage a lifestyle of continuous spiritual growth.
