In Spanish America and in French America the history of Negro religion is bound up with the history of the Catholic Church. On the other hand in the present territory of the United States with the exception of Maryland and Louisiana organized religion was practically and almost exclusively Protestant and Catholics indeed were often bracketed with Negroes for persecution. They could not marry Protestants at one time in colonial South Carolina; Catholics and Negroes could not appear in court as witnesses in Virginia by the law of 1705; Negroes and Catholics were held to be the cause of the “Negro plot” in New York in 1741. The work then of the Catholic Church among Negroes began in the United States well into the 19th century and by Negroes themselves. In Baltimore, for instance, in 1829, colored refugees from the French West Indies established a sisterhood and academy and gave an initial endowment of furniture, real estate and some $50,000 in money. In 1842 in New Orleans, four free Negro women gave their wealth to form the Sisters of the Holy Family and this work expanded and grew especially after 1893 when a mulatto, Thomy Lafon, endowed the work with over three quarters of a million dollars, his life savings. Later, in 1896, a colored man, Colonel John McKee of Philadelphia, left a million dollars in real estate to the Catholic Church for colored and white orphans. Outside of these colored sisterhoods and colored philanthropists, the church hesitated long before it began any systematic proselyting among Negroes. This was because of the comparative weakness of the church in early days and later when the Irish migration strengthened it the new Catholics were thrown into violent economic competition with slaves and free Negroes, and their fight to escape slave competition easily resolved itself into a serious anti-Negro hatred which was back of much of the rioting in Cincinnati, Philadelphia and New York. It was not then until the 20th century that the church began active work by establishing a special mission for Negroes and engaging in it nearly two hundred white priests. This new impetus was caused by the benevolence of Katherine Drexel and the Sisters of the Blessed Sacrament. Notwithstanding all this and since the beginning of the 18th century only six Negroes have been ordained to the Catholic priesthood.
