The US Constitution is NOT ordained by God, but rather man.
Let's begin this study from the Bible regarding government.
Is freedom of religion a biblical concept?
Yes according to numerous so called Christian apologetic studies on the subject found in link below in note (10) and used by rabid Christian Evangelicals and those others who venerate the Constitution going hand in hand with religion.
However, right off the bat we see a serious conflict. Let's examine the Preamble and the 1st Amendment closely:
"The First Amendment to the Constitution, ratified in 1791, provides that “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.” The absence of references to a deity in the Constitution is consistent with the strict religious neutrality of the entire document. (Additionally_)... the Constitution is hardly a document glorifying top-down power. On the contrary, the theory of government underpinning the United States Constitution is popular sovereignty. The government derives its legitimacy from the consent of the governed, not from an assembly of elders, not from a king or a prelate, and not from a higher power." (11)
Please find these words in the Bible or scripture that can harmonize with the 1st Amendment meaning of expression of and free exercise of "religion":
The First Amendment's Establishment Clause prohibits the government from making any law “respecting an establishment of religion.” This clause not only forbids the government from establishing an official religion, but also prohibits government actions that unduly favor one religion over another. It also prohibits the government from unduly preferring religion over non-religion, or non-religion over religion. Note (11)
First Amendment's The Free Exercise Clause reserves the right of American citizens to accept any religious belief and engage in religious rituals. Free-exercise clauses of state constitutions which protected religious “[o]pinion, expression of opinion, and practice were all expressly protected” by the Free Exercise Clause. The Clause protects not just religious beliefs but actions made on behalf of those beliefs. More importantly, the wording of state constitutions suggest that “free exercise envisions religiously compelled exemptions from at least some generally applicable laws.” The Free Exercise Clause not only protects religious belief and expression; it also seems to allow for violation of laws, as long as that violation is made for religious reasons. In the terms of economic theory, the Free Exercise Clause promotes a free religious market by precluding taxation of religious activities by minority sects. Note (12)
Does this sound like biblical doctrine: In 1802, President Jefferson wrote a letter to a group of Baptists in Danbury, Connecticut, in which he declared that it was the purpose of the First Amendment to build ''a wall of separation between Church and State.''
In conclusion we know what God thinks about humanity and human reasoning including government and we know that God will establish is kingdom that will never end.
