David Berger (theologian)

David Berger (born 8 March 1968 in Würzburg) is a German theologian, author and gay activist.

Biography
From 1991 to 1998, Berger studied philosophy, Catholic theology and German language and literature in Würzburg, Cologne and Dortmund. Berger is a German neo-Thomist and took a critical stance to the work of Karl Rahner. Berger was a professor of the Pontifical Academy of St. Thomas Aquinas in Rome and also worked as a religious education teacher at a high school in Erftstadt, Germany. The Catholic Church has since revoked his licence to teach.

In 2010, Berger's homosexuality was publicized. He then published his book Der heilige Schein: Als schwuler Theologe in der katholischen Kirche ("The holy appearance: Being a gay theologian in the Catholic church"), in which he claimed that 20 to 40 percent of the Catholic clergy were homosexual.

He subsequently was the editor-in-chief of the gay periodical Männer (Berlin). He increasingly took a critical stance towards Islam and immigration, which in February 2015 led to him being dismissed from that position and to Berger distancing himself from the German LGBT movement. Berger continues as an independent blogger and supports, among other things, the German anti-migration party AfD.
