Constitution of Pennsylvania (1776)

Their Constitution stated in Frame of Government, Section 10: "And each member [of the legislature], before he takes his seat, shall make and subscribe the following declaration, viz: 'I do believe in one God, the Creator and Governour of the universe, the rewarder of the good and punisher of the wicked, and I do acknowledge the Scripture of the Old and New Testament to be given by Divine Inspiration.'"

This is the kind of requirement that the Framers of the U.S. Constitution were trying not to interfere with when they drafted the First Amendment. Many states had some form of officially-supported religion and were intent on keeping the Federal Government out of these matters.
