Christianity in general is riddled with them and has no place in the law of society.
Truthfully, our founding fathers disagreed. Were you aware that the term “Separation of Church and State” is nowhere in the constitution? It’s an interesting piece of history to find where it came from. But with that aside, I’m just going to address your ‘law of society’ quote.
From John Adams, signer of the Declaration of Independence:
**
t is religion and morality alone which can establish the principles upon which freedom can securely stand. The only foundation of a free constitution is pure virtue.
(Source: John Adams, The Works of John Adams, Second President of the United States, Charles Francis Adams, editor (Boston: Little, Brown, 1854), Vol. IX, p. 401, to Zabdiel Adams on June 21, 1776.)
[W]e have no government armed with power capable of contending with human passions unbridled by morality and religion. . . . Our constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.
(Source: John Adams, The Works of John Adams, Second President of the United States, Charles Francis Adams, editor (Boston: Little, Brown, and Co. 1854), Vol. IX, p. 229, October 11, 1798.)
From George Washington:
While just government protects all in their religious rights, true religion affords to government its surest support.
(Source: George Washington, The Writings of George Washington, John C. Fitzpatrick, editor (Washington, D.C.: U.S. Government Printing Office, 1932), Vol. XXX, p. 432 n., from his address to the Synod of the Dutch Reformed Church in North America, October 9, 1789.)
***Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports. In vain would that man claim the tribute of patriotism who should labor to subvert these great pillars of human happiness, these firmest props of the duties of man and citizens. The mere politician, equally with the pious man, ought to respect and to cherish them. A volume could not trace all their connexions with private and public felicity. Let it simply be asked, Where is the security for property, for reputation, for life, if the sense of religious obligation desert the oaths, which are the instruments of investigation in Courts of Justice?
And let us with caution indulge the supposition that morality can be maintained without religion. Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle. It is substantially true, that virtue or morality is a necessary spring of popular government. The rule, indeed, extends with more or less force to every species of free government. Who, that is a sincere friend to it, can look with indifference upon attempts to shake the foundation of the fabric?***

My only point–and I could pull in quotes from more and more of the framers and signers of the constitution and Declaration of Independence if requested–is that moral law has an undeniable role in civil law. Often times you will hear the argument that religion never was intended to have any role in civil law, but this simply is not the case. Pretty neat stuff, if you ask me!

Be nice. It’s always best to assume the best in people.
