What was the original term?
Jefferson argued the point that the Constitution’s establishment clause forbade the government from creating a “state religion.” He did not express nor intend (by even a cursory review of his writings) any opinion forbidding the mention or inclusion of God in the public square, including government. A simple review of the writings of our founders, and their contemporaries, refutes this asinine insistence that a “separation of Church and State” requires the absolute and total banishment of God from the Public square. In fact, quite the opposite is true - and I could provide a litany of examples to support this contention.
