Article XX Sunday School

Subject for Lessons. SECT. 3.

"The first lessons of the children should be the Ten Commandments  (Exodus 20:3-17),

the Lord's Prayer  (Matt. 6:9-13), and its Spiritual Interpretation by Mary Baker Eddy,

Sermon on the Mount  (Matt. 5:3-12).

The next lessons consist of such questions and answers as are adapted to a juvenile class,
and may be found in the Christian Science Quarterly Lessons, read in Church services.
The instruction given by the children's teachers must not deviate from the absolute Christian
Science contained in their textbook."
