Not Participating in Sunday School
Sunday School, which in some circles is more compulsory than church attendance, began in the late 18th century as a literal school for working class children, who during the Industrial Revolution worked 12-hour days Monday through Saturday, and thereby had no opportunity to learn to read, write, or educate themselves beyond serfdom.
This worthy endeavor morphed into what we experience today, a segregation of ages and demographics — young marrieds here, 6th graders there, retired persons in the front foyer, children in the basement — that adds another hour of community obligation to the day of rest.
If you like it, and you’re learning from Sunday School, then participate with joy. If you’re not interested, then don’t feel like a pariah.
