Over 160 years ago, former Roman Catholic Priest, Charles Chiniquy was making the case that the Roman Catholic Church was active in infiltrating American public education. He also warned of dangers of Catholic immigration into protestant America. His book titled Rome and Education is an excellent resource.
Charles P. Chiniquy (30 July 1809 – 16 January 1899) was a French-Canadian Catholic priest who left the Roman Catholic Church after coming to true Biblical salvation. As a Catholic Priest he had established a Catholic colony in St. Ann Illinois later converting his parish to a Presbyterian Church. He rode the lecture circuit denouncing the Catholic Church. He warned of plots by the Vatican to take control of the United States by importing Catholic immigrants from Ireland, Germany, and France, and suggested that the Vatican was behind the assassination of Abraham Lincoln. He authored many books and spent his remaining years trying to rescue the lost held in bondage to the Church of Rome.
