“I was sorry to see the gloomy picture which you drew of the affairs of your Country in your letter of December; but I hope events have not turned out so badly as you then apprehended. Of all the animosities which have existed among mankind, those which are caused by a difference of sentiments in religion appear to be the most inveterate and distressing, and ought most to be deprecated. I was in hopes, that the enlightened and liberal policy, which has marked the present age, would at least have reconciled Christians of every denomination so far, that we should never again see their religious disputes carried to such a pitch as to endanger the peace of Society.[Letter to Edward Newenham, 20 October 1792 about violence between Catholics and Protestants]”

“I regret exceedingly that the disputes between the protestants and Roman Catholics should be carried to the serious alarming height mentioned in your letters. Religious controversies are always productive of more acrimony and irreconcilable hatreds than those which spring from any other cause; and I was not without hopes that the enlightened and liberal policy of the present age would have put an effectual stop to contentions of this kind.[Letter to Sir Edward Newenham, 22 June 1792]”

“Religious controversies are always productive of more acrimony and irreconcilable hatreds than those which spring from any other cause. I had hoped that liberal and enlightened thought would have reconciled the Christians so that their religious fights would not endanger the peace of Society.”

“As Mankind becomes more liberal, they will be more apt to allow that all those who conduct themselves as worthy members of the community are equally entitled to the protections of civil government. I hope ever to see America among the foremost nations of justice and liberality.”

“Nothing can illustrate these observations more forcibly, than a recollection of the happy conjuncture of times and circumstances, under which our Republic assumed its rank among the Nations; The foundation of our Empire was not laid in the gloomy age of Ignorance and Superstition, but at an Epoch when the rights of mankind were better understood and more clearly defined, than at any former period, the researches of the human mind, after social happiness, have been carried to a great extent, the Treasures of knowledge, acquired by the labours of Philosophers, Sages and Legislatures, through a long succession of years, are laid open for our use, and their collected wisdom may be happily applied in the Establishment of our forms of Government; the free cultivation of Letters, the unbounded extension of Commerce, the progressive refinement of Manners, the growing liberality of sentiment... have had a meliorating influence on mankind and increased the blessings of Society. At this auspicious period, the United States came into existence as a Nation, and if their Citizens should not be completely free and happy, the fault will be entirely their own.[Circular to the States, 8 June 1783 - Writings 26:484--89]”

“To enlarge the sphere of social happiness is worthy of the benevolent design of a Masonic institution; and it is most fervently to be wished, that the conduct of every member of the fraternity, as well as those publications, that discover the principles which actuate them, may tend to convince mankind that the grand object of Masonry is to promote the happiness of the human race.[Letter to the Grand Lodge of Free and Accepted Masons for the Commonwealth of Massachusetts, January 1793]”

“Hence, likewise, they will avoid the necessity of those overgrown military establishments, which, under any form of government, are inauspicious to liberty, and which are to be regarded as particularly hostile to Republican Liberty. In this sense it is, that your Union ought to be considered as a main prop of your liberty, and that the love of the one ought to endear to you the preservation of the other.”
