But it's worth focusing on their address to him. Religious leaders constantly corresponded with Washington, praising him, seemingly both to try to smell him out and proselytize to him. Washington invariably responded with generic, inclusive head nodding language that affirmed his belief in a monotheistic Providence (as he does here).
An Address from the New Church at Baltimore, To George Washington, Esquire
While the Nations of the Earth, and the people of United America especially, have in their various denominations paid their tribute to the respectful deference to the illustrious President thereof, permit, for a Society however small in number, yet sincere they trust, in their attachment to offer up in the dawn of their institution, that mark of dutiful esteem which will become the new associations, to the Chief Magistrate of America.
We presume not, Sir, to enter into a reiterated panegyric of matchless virtues or exalted character, but assuming causes with effects, we are led to believe that you were a chosen vessel for great Salutary purposes, and that both in your actions and in your conduct, you justly stand one of the first disinterested and exemplary men upon earth. Neither in this address can we, was it expected, enter into a detail of the profession of our faith; but we are free to declare that we feel ourselves among the number of those who have occasion to rejoice that the word literally is spiritually fulfilling; that a new and glorious dispensation or fresh manifestation of Divine Love hath commenced in our Land; when as there is but one Lord, so is his name becoming one throughout the earth; & that the power of Light or truth and righteousness is in an eminent Degree, universally prevailing, and even triumphing over the powers of Darkness; when Priestcraft & Kingcraft, those banes of human felicity, are hiding their diminished heads, and equality in State, as well as in Church, proportionally to mind, are considered the true criterion of the majesty of the people. -- Oh! Sir, could we, without being charged with adulation, pour out the fullness of our souls to the enlightened conduct of him who stands chief among the foremost of men, what a volume of truth might we deservedly offer to the name of Washington, on the altar of Liberty uncircumscribed! Allow us, by the first opportunity, to present to your Excellency, among other Tracts, the Compendium of the New Church, signified by the New Jerusalem, as the readiest mean to furnish you with a just idea of the Heavenly Doctrines.
That the Lord Jesus, whom alone we acknowledge as "the true God & eternal Life," will preserve you long to reign in the hearts of the people, and lastly to shine as a gem of the brightest lustre, a Star of the first magnitude of the unfading mansions above, is the fervent aspiration of your faithful citizens and affectionate Brethren. Done in behalf of the members of the Lord's New Church at Baltimore, this 22d Day of January 1793 -- 37.
Secy. ProtemWhile they could not "enter into a detail of the profession of [their] faith," they still did proselytize for their unorthodox understanding of the Christian faith. They were modalists, believing the Father, Son & Holy Spirit were One Person, not Three Persons. While most modalists believe the three names are just three different titles or "modes" of One God, the Swedenborgs believed that One Person was Jesus Christ. (That Jesus wasn't just the "mode" of the Son; He was the "mode" of all three).
