In this essay, he claims that he could no longer handle the "homophobia". In reality, he was fired from his position and would presumably have continued his double life of fancy meals and expensive wines in ancient castles.

Berger: Ever since Pope Benedict XVI, at the latest, you have to be anti-modern to have a career in the Catholic Church. I criticized the relatively progressive theology and left-wing church policy of Karl Rahner. That is how people noticed me.

I was in touch with the Sedevacantists, the Priestly Fraternity of St. Peter, the Society for the Defense of Tradition, Family and Property, Una Voce, Opus Dei and the Servants of Jesus and Mary.
