“Allow me briefly to allude to some of these improvements. The question of building up class interests, or fostering one branch of industry to the prejudice of another under the exercise of the revenue power, which gave us so much trouble under the old constitution, is put at rest forever under the new. We allow the imposition of no duty with a view of giving advantage to one class of persons, in any trade or business, over those of another. All, under our system, stand upon the same broad principles of perfect equality. Honest labor and enterprise are left free and unrestricted in whatever pursuit they may be engaged. This old thorn of the tariff, which was the cause of so much irritation in the old body politic, is removed forever from the new.”

General sources
Context: It has in all ages been allowed that the communion of saints extends to those in paradise as well as those upon earth as they are all one body united under one Head. And "Can death’s interposing tide / Spirits one in Christ divide?" But it is difficult to say either what kind or what degree of union may be between them. It is not improbable their fellowship with us is far more sensible than ours with them. Suppose any of them are present, they are hid from our eyes, but we are not hid from their sight. They no doubt clearly discern all our words and actions, if not all our thoughts too; for it is hard to think these walls of flesh and blood can intercept the view of an angelic being. But we have in general only a faint and indistinct perception of their presence, unless in some peculiar instances, where it may answer some gracious ends of Divine Providence. Then it may please God to permit that they should be perceptible, either by some of our outward senses or by an internal sense for which human language has not any name. But I suppose this is not a common blessing. I have known but few instances of it. To keep up constant and close communion with God is the most likely means to obtain this also.

1790s
Context: The Citizens of the United States of America have a right to applaud themselves for giving to Mankind examples of an enlarged and liberal policy: a policy worthy of imitation. All possess alike liberty of conscience and immunities of citizenship. It is now no more that toleration is spoken of, as if it was by the indulgence of one class of people that another enjoyed the exercise of their inherent natural rights. For happily the Government of the United States, which gives to bigotry no sanction, to persecution no assistance, requires only that they who live under its protection should demean themselves as good citizens in giving it on all occasions their effectual support.
May the Children of the Stock of Abraham, who dwell in this land, continue to merit and enjoy the good will of the other Inhabitants; while every one shall sit under his own vine and fig tree, and there shall be none to make him afraid.
