Parishioners worshipping at St. Charles Borromeo Catholic Church in Harlem are greeted by a framed portrait of Martin Luther King Jr. — a Baptist minister named after a rebellious 16th century German priest excommunicated from the Catholic Church. The Rev. Bryan Massingale, who sometimes preaches at St. Charles, pursues his ministry in ways that echo both Martin Luthers. Like King, Massingale decries the scourge of racial inequality in the United States. As a professor at Fordham University, he teaches African American religious approaches to ethics. Like the German Martin Luther, Massingale is often at odds with official Catholic teaching — he supports the ordination of women and making celibacy optional for Catholic clergy. And, as a gay man, he vocally disagrees with the church’s doctrine on same-sex relations, instead advocating for full inclusion of LGBTQ Catholics within the church.
