While I'm not sure I know what is meant by the "Americanist Heresy," I will note that the artist here is represented as saying that "[i]n my painting I used the 'Da Vinci - Last Supper' to represent the Covenant our Lord has made with the people of this land." There is no scriptural support for such a statement, which is surely incorrect, if not altogether heretical.
The only nation that has been in a corporate covenantal relationship with God is Israel -- i.e., the Jews. God has made no "covenant" with the people of the United States. To the extent this painting is meant to communicate that such a "covenant" exists or has ever existed, it is idolatrous nonsense.
YOU ARE OBVIOUSLY CORRECT, BUT FOR ONE DETAIL, SUBJECT TO INTERPRETATION.
GENESIS 12:3
“I will bless those who bless you
And curse the one who curses you;”
NOW, THE UNITED STATES OF AMERICA, AS A NATION UNDER THE CONSTITUTION, HAS NEVER TREATED THE CHILDREN OF ISRAEL, THE DECEDENTS OF ABRAHAM, WITH WHOM G-D MADE AN EVERLASTING COVENANT INHERITED ONLY BY THE CHILDREN OF ISRAEL, IN ANY DISCRIMINATORY MANNER WHATSOEVER. JEWS, IN AMERICA, ARE JUST LIKE EVERYBODY ELSE, NO DIFFERENT THAN ANY OTHER RESIDENT. THEY ARE NOT FORCED TO WEAR DISTINGUISHING CLOTHING, BARRED FROM PROFESSIONS, OR OWNING LAND, OR KEEPING AND BEARING ARMS, VOTING, OR PARTICIPATING FULLY AND EQUALLY IN CIVIC LIFE, OR SOCIETY.
GRANTED, THERE ARE INDIVIDUALS WHO HATE AND CURSE JEWS, PRIVATE INSTITUTIONS THAT DO SO ALSO, EVEN ORGANS OF THE GOVERNMENT THAT, BY “GENTLEMAN’S AGREEMENT” DO SO, BUT THE LAW OF THE LAND, THE CONSTITUTION, HAS NEVER TREATED THE JEW AS BUT ANOTHER RESIDENT, EQUAL TO ALL OTHERS.
I AM OF THE OPINION, AS A JEW, BORN IN A DISPLACED PERSONS CAMP IN EUROPE AFTER THE SECOND WORLD WAR, THAT THIS NON-DISCRIMINATORY POLICY OF THE CONSTITUTION, THIS NATION, IS A VERY REAL AND RARE BLESSING OF THE DESCENDANTS OF THE COVENANT, AND THEREFORE IS RIGHTFULLY BLESSED BY G-D AS HE SWORE TO DO.
OFF HAND, I CANNOT THINK OF ANOTHER NATION THAT HAS SO BLESSED THE DECEDENTS OF THE COVENANT. HOLLAND, CANADA PERHAPS?
THE UNITED STATES OF AMERICA, FOR SURE, EVEN BEFORE ITS FOUNDING.
SO, YES, G-D BLESS THE UNITED STATES OF AMERICA, FOR SHE HAS BLESSED THE PEOPLE OF THE COVENANT.
Washington believed our budding nation was actively being smiled upon by divine Providence. Most who fought with or against Washington and saw him go in harm’s way battle after battle, year after year, got the distinct sense that the Creator was protecting him against harm or death. Both of these things may be true, and the artist here may merely be reflecting these general beliefs.
The U.S.A. however has not got a hall pass to reinvent the Kingdom of Heaven within our borders. Christ is King, here, there and everywhere. No president, Kennedy included (and now, ostensibly at least, Brandon) can be heard to say or suggest otherwise.
Clearly this line of spiritual doctrine is held to by none but authentic Catholics in this day and age, particularly in the U.S.A., where individual up and down our social strara insist on the power of personal freedom, including the right to view Christ in the manner of their choosing, or reject him entirely. This is Americanism, and it has been strongly and specifically called out at the highest levels of Holy Mother Church as a pernicious heresy, much to be dreaded.
