The Rev. James Martin, a popular priest who published a book earlier this year encouraging a bridge between the LGBT community and the Catholic Church, has been disinvited from giving an address at Catholic University’s seminary.

Martin, who was planning to speak about Jesus and not about LGBT-related issues, has become the target of attacks from right-wing sites since his book “Building a Bridge” was published in June.

In a statement, the university’s seminary, Theological College, said that it had received negative feedback on social-media sites and that its rector, the Rev. Gerald McBrearity, made the decision to rescind Martin’s invitation to speak in October. Martin is editor at large at the Jesuit magazine America.
