I took a college survey course in Christianity way back in the '80s and of the two books assigned for the Catholic phase of our studies I remember a book called "What Are The Theologians Saying?" (1970) by German theologian Monika Hellwig.
Frau Hellwig was very selective in her choice of topics and what do you know? All the theologians leaned left. I don't think they made one correct prediction about the future of the Church. Imagine that.
