The University of San Diego recently revoked a British theology professor’s speaking invitation because the professor signed a letter supporting civil marriage rights for same-sex couples in the United Kingdom.

Tina Beattie, a professor of Catholic Studies at the University of Roehampton in London, was scheduled to give a lecture on art depicting sin and redemption at the University of San Diego on November 8 .USD withdrew that invitation on October 27. University President Mary Lyons explained it was because Beattie publicly dissents from the church’s moral teachings.

Beattie said the withdrawn invitation raises concerns about the school’s commitment to academic freedom. The University of San Diego did not respond to requests for an interview.

University faculty concerned about academic freedom have put up this website to make documents concerning this issue available.
