Very first law extant in America:
http://www.vagenweb.org/hening/vol01-05.htm
THAT there shall be in every plantation, where the people use to meete for the worship of God, a house or roome sequestred for that purpose, and not to be for any temporal use whatsoever, and a place empaled in, sequestered only to the buryal of the dead.
And certainly not laws made up by Joe Smith, latecomer & wannabe.
On the other hand, I’m not sure they anticipated a conspiracy of conquest masquerading as a religion (Islam).
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof;
Only Congress has the power to establish a religion and they are restricted from doing so. God in the Pledge of Allegiance does not establish a religion. A prayer in school does not establish a religion, and a manger scene on public property does not establish a religion. People saying the Lord Jesus Christ's name does not establish a religion. Congress passing a law that says we all have to go to the Glory Bound Baptist Church every Sunday establishes a religion.
Now, Congress is also forbidden from prohibiting the free exercise thereof. Hence, the law of the land says you can not tell me that I can not put a manger scene or the Ten Commandments up. You can not tell me I can not pray. You can not tell me I can not say the Lord's name.
Socialist/Communist wish to remove God from public view so you and I will begin to forget about God. Why do they want you to forget about God? Well, I am an American. I pray to my God and we handle my problems. I do not pray to my Government. Once people have forgotten how to pray to their God for help, they will begin to pray to the Government for help. From the cradle to the grave.
It is imperative that we keep God in public view.
