There's a lot of misunderstandings about the Constitution. It doesn't give rights...it limits the Government's ability to infringe upon your rights.
Not even close. "Christianity" and the Constitution are mutually exclusive.
The Constitutional convention began as a convention to
suggest changes to the Articles of Confederation which would be reported back to that Congress and voted on by them (North, p. 379 and pp. 414-415),
not to create a new form of government or a new constitution. From the beginning, there was little mention of building a Christian civil covenant. The issue of framing the Constitution was more one of balance of powers and how well the government would work than on whether or not to create a Christian civil covenant (Stanley N. Katz ,"The Origins of Constitutional Thought." Journal of Church and State, Volume 3, 1969). What was foremost in the mind of the framers was not Christianity.
"The Constitution reflects our founders views of a secular government, protecting the freedom of any belief or unbelief. The historian, Robert Middlekauff, observed, 'the idea that the Constitution expressed a moral view seems absurd. There were no genuine evangelicalism the Convention, and there were no heated declarations of Christian piety" (Jim Walker, Little Known U.S. Documents Signed by President Adams Proclaims America's Government is Secular, Early America Review, Summer 1997).
The Founders thought more of the idea of a secular state than how to please God (Derek H. Davis, Religious Pluralism and the Quest for Unity in American Life, Journal of Church and State, vol. 36, no. 2, Spring 1994). Even when the Convention was at an impasse and Franklin urged them to pray and ask for help, it was voted down (North, page 426).
The first criteria for a Christian civil government is a recognition of God as sovereign. Not only is Christ not recognized in the Constitution, there is no hint of God at all. The sovereign recognized in the Constitution is not God, it is the people. The Constitution is a covenant but not with God. "But no consideration will justify the framers of the federal constitution, and the administration of the government in withholding a recognition of the Lord and his Anointed from the grand charter of the nation. On our daily bread, we ask a blessing. At our ordinary meals, we acknowledge the Lord of the world. We begin our last testament for disposing of worldly estates, in the name of God: and we shall be guiltless, with the Bible in our hands, to disclaim the Christian religion as a body politic" (Alexander M'Leod, The Moral Character of the Constitution).
The Founding Fathers apostatized from the Godly civil covenants of their and our forefathers. When they rejected God, they also rejected God's law. Thornwell concluded from the Founder's rejection of God, "They became a law unto themselves; there was nothing beyond them to check or control their caprices or their pleasure" (Thornwell, The Relation of the State to Christ).
People can talk all they want to about a Christian Constitution, but they will never be able to get around the fact that God is not even mentioned in it. Thornwell recognized this and said, "The fundamental error of our fathers was, that they accepted a partial for a complete statement of the truth. They saw clearly the human side-- that popular governments are the offspring of popular will; and that rulers, as the servants and not the masters of their subjects, are properly responsible to them. They failed to apprehend the Divine side-- that all just government is the ordinance of God, and that magistrates are His ministers who must answer to Him for the execution of their trust. The consequence of this failure, and of exclusive attention to a single aspect of the case, was to invest the people with a species of supremacy as insulting to God as it was injurious to them" (Thornwell, The Relation of the State to Christ).
Basically it says that congress shall not endorse or prohibit the Worship of Christianity in the manner you choose to do so. (Not atheism, Buddhism, Islam, or flying spaghetti monsters)
The Constitution states: "Congress shall make no law regarding an establishment of
religion, or prohibiting the
free exercise thereof" (First Amendment).
Do you realize that the Constitution allows everybody to freely worship any god they choose to? This is one of the greatest abominations to God.
Old Testament Israel had this same exact law also, and God would punish them whenever they enacted this law. Whenever people would worship other gods in his country, he would command them to tear down their temples and idols. If they refused, God would always punish his people. Even if there was a mixture of people worshipping the True God and people worshipping false gods, this was an abomination also, as his people are not to mix the two. God even commanded his people to go to neighboring countries of the heathen and tear down their temples and idols.
The truth is, the freedom of religion is an abomination to God. Man only has the "right" to worship Almighty God. To be free to worship any other god or partake of any other religion is an abomination to him, and violates the first Two Commandments:
Exodus 20:3-5, "Thou shalt have no other gods before me. Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: Thou shalt not bow down thyself to them, nor serve them:"
