Anyone who says there is can shut me up by simply posting where it is in the constitution.
The phrase "separation of church and state" does not appear anywhere in the Constitution.
Things That Are Not In the U.S. Constitution - The U.S. Constitution Online - USConstitution.net
This is what the constitution does say;
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.
This provision was put into the constitution to protect people from governmental intervention in their religion or establishing a state religion. It was not meant to prevent government from having religion in it. So all you Sea Lawyers out there who keep flapping your gums about the Separation of Church and State are all full of crap.
