Sunday School is a spiritual organization functioning in all the parishes of the Orthodox Church throughout the world. It takes care of the spiritual nurturing of the children, by bringing them up in the knowledge and fellowship of Jesus Christ and His Church. The Orthodox Church from the very beginning took utmost care in educating the Children the Values of Christian life, the contents of the Bible and the Church history. The “Koonen Cross Vow” in 1653 was a turning point. It emphasized the need for Catechism and Scriptural studies. During the 1765-1808 period, the study of sacraments and prayers were also included in the lessons. This was the beginning of the Sunday school in the Church. The classes range from Pre-Kindergarten to the 12th grade. We follow a curriculum, jointly prepared and published by the Oriental Orthodox Churches which is revised from time to time.
