I was planning the agenda for a Sunday School staff meeting in my church. I wanted to come up with an inspired way to encourage honest self-evaluation of the job we were doing as teachers.
The idea came to invite a guest speaker. I wanted someone who would have the greatest possible understanding of the appropriate procedures to follow for establishing a more effective Sunday School. It became immediately apparent that the only person to fill this role was Mary Baker Eddy. She could speak to us through her provisions for Sunday School in the Manual of The Mother Church.
At the meeting, we passed out copies of the Church Manual and opened to Article XX. There, in just six sentences, is every guideline, procedure, and directive a Sunday School teacher will ever need to know about.
