"Statesmen, my dear Sir, may plan and speculate for liberty, but it 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, and if this cannot be inspired into our People in a greater Measure, than they have it now, they may change their Rulers and the forms of Government, but they will not obtain a lasting liberty." - John Adams
In concern for his sons, John Adams advised his wife Abigail to:
"Let them revere nothing but Religion, Morality and Liberty."
"We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge, or gallantry, would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government ofany other." - John Adams
"I have thought proper to recommend, and I hereby recommend accordingly, that Thursday, the twenty-fifth day of April next, be observed throughout the United States of America as a day of solemn humiliation, fasting and prayer; that the citizens on that day abstain, as far as may be, from their secular occupation, and devote the time to the sacred duties of religion, in public and in private; that they call to mind our numerous offenses against the most high God, confess them before Him with the sincerest penitence, implore his pardoning mercy, through the Great Mediator and Redeemer, for our past transgressions, and that through the grace of His Holy Spirit, we may be disposed and enabled to yield a more suitable obedience to his righteous requisitions in time to come; that He would interpose to arrest the progress of that impiety and licentiousness in principle and practice so offensive to Himself and so ruinous to mankind; that He would make us deeply sensible that "righteousness exalteth a nation but sin is a reproach to any people" (Proverbs 14:34)" - John Adams
"Religion and virtue are the only foundations, not only of all free government, but of social felicity under all governments and in all the combinations of human society." - John Adams
"Have you ever found in history, one single example of a Nation thoroughly corrupted that was afterwards restored to virtue?... And without virtue, there can be no political liberty....Will you tell me how to prevent riches from becoming the effects of temperance and industry? Will you tell me how to prevent luxury from producing effeminacy, intoxication, extravagance, vice and folly?...I believe no effort in favor is lost..." - John Adams
"We have this day restored the Sovereign to Whom all men ought to be obedient. He reigns in heaven and from the rising to the setting of the sun, let His kingdom come."
"He therefore is the truest friend to the liberty of this country who tries most to promote its virtue, and who, so far as his power and influence extend, will not suffer a man to be chosen into any office of power and trust who is not a wise and virtuous man....The sum of all is, if we would most truly enjoy this gift of Heaven, let us become a virtuous people." - Samuel Adams
"Among the natural rights of the colonists are these: first, a right to life; second, to liberty; third, to property; together with the right to support and defend them in the best manner they can..."The rights of the colonists as Christians...may be best understood by reading and carefully studying the institution of The Great Law Giver and Head of the Christian Church, which are to be found clearly written and promulgated in the New Testament."
"Should not the Bible regain the place it once held as a schoolbook? Its morals are pure, its examples are captivating and noble....In no Book is there so good English, so pure and so elegant, and by teaching all the same they will speak alike, and the Bible will justly remain the standard of language as well as of faith." - Fisher Ames, author of the First Amendment
"I have lived, Sir, a long time, and the longer I live, the more convincing proofs I see of this truth--that God Governs the affairs of men. And if a sparrow cannot fall to the ground without His notice, is it probable that an empire can rise without His aid?
"We have been assured, Sir, in the Sacred Writings, that "except the Lord build the House, they labor in vain that build it." I firmly believe this; and I also believe that without his concurring aid we shall succeed in this political building no better than the Builders of Babel: We shall be divided by our partial local interests; our projects will be confounded, and we ourselves shall become a reproach and bye word down to future ages. And what is worse, mankind may hereafter from this unfortunate instance, despair of establishing Governments by Human wisdom and leave it to chance, war and conquest.
"I therefore beg leave to move--that henceforth prayers imploring the assistance of Heaven, and its blessing on our deliberations, be held in this Assembly every morning before we proceed to business, and that one or more of the clergy of this city be requested to officiate in that service." - Benjamin Franklin
"It cannot be emphasized too strongly or too often that this great nation was founded, not by religionists, but by Christians; not on religions, but on the Gospel of Jesus Christ. For this very reason peoples of other faiths have been afforded asylum, prosperity, and freedom of worship here."
"The Bible is worth all other books which have ever been printed."
"Bad men cannot make good citizens. A vitiated state of morals, a corrupted public conscience are incompatible with freedom."
"It is when people forget God that tyrants forge their chains." - Patrick Henry
I could post these all night...there's plenty more where that came from.
Don't bother. None of it supports your argument. You stated that the Founders were not libertarians. That is false. You supplied numerous quotes, mostly from John Adams (Abigail Adams was NOT one of the Founders) on the subject of morality and religion. Not a single one of those quotes establishes any of the founders as non-libertarians. It simply establishes them as men of moral character. There isn't a single quote in there that establishes morality based on any religious belief as the law of the land. You won't find any such thing in their writings either. And with good reason. How hypocritical it would have been of them to do such a thing and then to produce the First Amendment.
