Walker and C. T. Vivian. Black Power movement After the assassination of Dr. King in 1968, Black Catholics began organizing en masse, beginning with the clergy that April. A Black Catholic revolution soon broke out, fostering the integration of the traditions of the larger (Protestant) Black Church into Black Catholic parishes. Soon there were organizations formed for Black religious sisters (1968), permanent deacons, seminarians, and a brand-new National Black Catholic Congress organization in 1987, reviving the late 19th-century iteration of the same. This era saw a massive increase in Black priests, and the first crop of Black bishops and archbishops. Black theology One formalization of theology based on themes of black liberation is the black theology movement. Its origins can be traced to July 31, 1966, when an ad hoc group of 51 black pastors, calling themselves the National Committee of Negro Churchmen (NCNC), bought a full-page ad in The New York Times to publish their "Black Power Statement", which proposed a more aggressive approach to combating racism using the Bible for inspiration. Black liberation theology was first systematized by James Cone and Dwight Hopkins. They are considered the leading theologians of this system of belief, although now there are many scholars who have contributed a great deal to the field. In 1969, Cone published the seminal work that laid the basis for black liberation theology, Black Theology and Black Power. In the book, Cone asserted that not only was black power not alien to the Gospel, it was, in fact, the Gospel message for all of 20th century America. In 2008, approximately one quarter of African-American churches followed a liberation theology. The theology was thrust into the national spotlight after a controversy arose related to preaching by Rev. Jeremiah Wright, former pastor to then-Senator Barack Obama at Trinity United Church of Christ, Chicago. Wright had built Trinity into a successful megachurch following the theology developed by Cone, who has said that he would "point to [Trinity] first" as an example of a church's embodying his message. Scholars have seen parallels between the Black church and the 21st Century Black Girl Magic movement, with social media interactions involving the Black Girl Magic hashtag seen as a modern extension of "[t]he Black church traditions of testimony, exhortation, improvisation, call and response, and song," which Black women can use to form a "cyber congregation."
