[From "John Calvin Could Not Be Happier (2022)"]

Do you realize that Christmas Day was not declared a Federal holiday until June 26, 1870, principally because of the large number of Catholics who had come to this country from Europe[…]?

Yes, the principal "holiday" of celebration in the latter part of a calendar year between 1607[…]and 1870, a period of two hundred sixty-three years, was "thanksgiving day"[…]
The American concept of "thanksgiving day"[…]has its roots with the Pilgrims of the Plymouth Colony who, as followers of John Calvin, were desirous of a total separation from the Church of England, which had, they believed, too much of the vestigial trappings of Catholicism[…]were giving thanks to God for having placed them in a land that they believed had not been "polluted" by what they hated most: the Holy Mass[…]
The first American Thanksgiving, though, took place on September 8, 1565, the Feast of the Nativity of the Blessed Virgin Mary, in Saint Augustine, Florida. It included a Mass of Thanksgiving offered by Father Francisco Lopez de Mendoza Grajales. The Americas were indeed Catholic and they belonged to Our Lady long before those horrible Catholic-hating, Mass-hating Calvinists[…]
Calvinism, which is really warmed over Judaism with a slightly Christian gloss, is at the heart and soul of life here in the United States of America[…]
Yes, Christmas Day is still a Federal holiday. References to "Merry Christmas" and "Christmas Day." however, are strictly forbidden in most commercial establishments[…]
The American "thanksgiving day" has thus become the true embodiment of the ethos of religious indifferentism and cultural pluralism, a celebration of family traditions while the traditions of the true Faith have been consigned to the Orwellian memory well both by the forces of Calvinism/Judeo-Masonry and by the liturgical revolutionaries of conciliarism
