Lutheran schools and churches have always gone hand in hand. Martin Luther, all the way back in 1530, wrote “A Sermon on Keeping Children in School,” and he was quite the revolutionary as he called for the education of not only boys but girls as well.
This desire to educate our children was kept by the Saxon (and other) immigrants who would form the Missouri Synod. In Germany, religious instruction was a part of the public school curriculum. In America, however, the public schools were much more secular, or the Christianity that was taught in them was generic and watered down. So in many places, Lutherans established their schools first and then, a few years later, built their church.
