Why does the Seventh-day Adventist Church have a Church Manual? God is a God of order as evidenced in His works of creation and redemption. Consequently, order belongs to the essence of His church. Order is achieved through principles and regulations that guide the Church in its internal operations and in the fulfillment of its mission to the world. In order for it to be a successful ecclesiastical organization at the service of the Lord and humanity, it needs order, rule, and discipline. Scripture affirms that “all things be done decently and in order” (1 Cor. 14:40)
