The traditional way was that children would stay home, and be taught the Bible by their parents. Now most Americans leave it up to the government to teach their children.
Here are a few facts about traditional America:
In 1777, Congress, facing a National shortage of `Bibles for our schools, and families, and for the public worship of God in our churches,' announced that they `desired to have a Bible printed under their care & by their encouragement' and therefore ordered 20,000 copies of the Bible to be imported `into the different ports of the States of the Union'.
In 1782, Congress pursued a plan to print a Bible that would be `a neat edition of the Holy Scriptures for the use of schools' and therefore approved the production of the first English language Bible printed in America that contained the congressional endorsement that `the United States in Congress assembled . . . recommend this edition of the Bible to the inhabitants of the United States'.
In 1789, Congress, in the midst of framing the Bill of Rights and the First Amendment, passed the first Federal law touching education, declaring that `Religion, morality, and knowledge, being necessary to good government and the happiness of mankind, schools and the means of education shall forever be encouraged'.
