The sermon that Samuel Cooper gave on the day of commencement for the Constitution in 1780 is a truly wonderful read, it you are interested you may find it here:
He truly believed in what was being created in this United States of America and he played his part in teaching the people who followed him. He didn’t shy away and say pastors should stay out of politics. He and so many other pastors of his day were instrumental in shaping the future of this country. Far from thinking that their place was separate, they believed themselves an essential part of the fabric of the country. They probably would be amazed and horrified to find that far from a country that followed the tenets of Biblical Law, we are fast becoming a nation that has no center at all and in fact is just as likely to follow Shariah law. From the Online Library of Liberty we find the following about him and an excerpt from one of his sermons:
The Massachusetts clergyman Samuel Cooper (1725-1783) gave a patriotic sermon in 1780 to celebrate the adoption of the Articles of Confederation. He concludes by urging his listeners to help build “the new city” in America by making the wilderness fruitful, inviting the injured and oppressed to come to America, and to create a country which “breaths” the principles of “peace on earth, and good will towards men”
“… So favourable, through the divine superintendence, is the present situation of the powers in Europe, to the liberties and independence for which we are contending. But as individuals must part with some natural liberties for the sake of the security and advantages of society; the same kind of commutation must take place in the great republic of nations. The rights of kingdoms and states have their bounds; and as in our own establishment we are not likely to find reason, I trust we shall never have an inclination to exceed these bounds, and justly to excite the jealousy and opposition of other nations. It is thus wisdom, moderation and sound policy would connect kingdoms and states for their mutual advantage, and preserve the order and harmony of the world. In all this these free states will find their own security, and rise by natural and unenvied degrees to that eminence, for which, I would fain perswade myself, we are designed.
“It is laudable to lay the foundations of our republicks with extended views. Rome rose to empire because she early thought herself destined for it. The great object was continually before the eyes of her sons: It enlarged and invigorated their minds; it excited their vigilance; it elated their courage, and prepared them to embrace toils and dangers, and submit to every regulation friendly to the freedom and prosperity of Rome. They did great things because they believed themselves capable, and born to do them. They reverenced themselves and their country; and animated with unbounded respect for it, they every day added to its strength and glory. Conquest is not indeed the aim of these rising states; sound policy must ever forbid it: We have before us an object more truly great and honourable. We seem called by heaven to make a large portion of this globe a seat of knowledge and liberty, of agriculture, commerce, and arts, and what is more important than all, of christian piety and virtue. A celebrated British historian observes, if I well remember, that the natural features of America are peculiarly striking. Our mountains, our rivers and lakes have a singular air of dignity and grandeur. May our conduct correspond to the face of our country! At present an immense part of it lies as nature hath left it, and human labour and art have done but little, and brightened only some small specks of a continent that can afford ample means of subsistence to many, many millions of the human race. It remains with us and our posterity, to “make the wilderness become a fruitful field, and the desert blossom as the rose”; to establish the honour and happiness of this new world, as far as it may be justly our own, and to invite the injured and oppressed, the worthy and the good to these shores, by the most liberal governments, by wise political institutions, by cultivating the confidence and friendship of other nations, and by a sacred attention to that gospel that breaths “peace on earth, and good will towards men.” Thus will our country resemble the new city which St. John saw “coming down from God out of heaven, adorned as a bride for her husband.” Is there a benevolent spirit on earth, or on high, whom such a prospect would not delight?…
O thou supreme Governor of the world, whose arm hath done great things for us, establish the foundations of this commonwealth, and evermore defend it with the saving strength of thy right hand! Grant that here the divine constitutions of Jesus thy Son may ever be honoured and maintained! Grant that it may be the residence of all private and patriotic virtues, of all that enlightens and supports, all that sweetens and adorns human society, till the states and kingdoms of this world shall be swallowed up in thine own kingdom: In that, which alone is immortal, may we obtain a perfect citizenship, and enjoy in its completion, “the glorious Liberty of the Sons of God![”] And let all the people say, Amen!”
