I have two questions:
1. What is the history of having children's Sabbath School divisions?
Thank you for contacting the Ellen G. White Estate. The best place to find information like this, at least in brief, is in the Seventh-day Adventist Encyclopedia, which is volume 10 (now revised as volumes 10 and 11) of the SDA Bible Commentary set. In the article "Sabbath School" is this paragraph:
"Early Sabbath Schools had only two divisions, one for children and one for adults (the latter called the Bible Class). Teachers placed much emphasis on the memorization of Scripture. Adelia Patten wrote a series of Sabbath school lessons adapted for children in 1863. The same year the first adult Sabbath school lessons appeared in the Review and Herald and were written by Uriah Smith."
2. What is the counsel regarding children's Sabbath School? What is supposed to be included in the children's Sabbath School?
Have a great day! ___________
The most likely place to look for such information is in the compilation "Counsels on Sabbath School Work." Given your interest in the subject, very likely you would want to purchase the book if you don't already have a copy. The book does not include a chapter devoted just to the children's Sabbath School, but in the book's index you will find quite a lengthy section on children. As I looked it over, it appeared to me to concentrate more on the principles than on the specifics, such as what should be included in the children's Sabbath school. You will probably not find Mrs. White addressing herself to that latter question very much if at all. And perhaps this is well, since methods and applications may vary according to circumstance and other factors. But the principles will guide us in finding the right application.
I hope this may be helpful. Thank you for writing, and God bless!
