Mary Baker Eddy

“ The Sabbath School children shall be taught the Scriptures, and they shall be instructed according to their understanding or ability to grasp the simpler meanings of the divine Principle that they are taught. ”

“ Pupils may be received in the Sunday School classes of any Church of Christ, Scientist, up to the age of twenty years, and by transfer from another Church of Christ, Scientist, up to that age, but no pupil shall remain in the Sunday School of any Church of Christ, Scientist, after reaching the age of twenty. None except the officers, teachers, and pupils should attend the Sunday School exercises. ”
