697. What is the content and objective of divine services for children?

In addition to Sunday School, there are also divine services for children from time to time, in both smaller and larger circles. The word of God is imparted by priestly ministers in a manner corresponding to the understanding of the children. The ministers thereby help the children understand God and His work. That which the children can comprehend on the basis of their own experiences will become a foundation of faith to them on their path of life.
The children’s service goes into the needs of the children. They are to feel understood, secure, and loved. It is a special experience for them to participate in a divine service in their own circle and celebrate Holy Communion together in the process.
