Kung, a Swiss theologian known for being banned from teaching theology shortly after his important role in Vatican II, has written a concise narrative of the history of the Catholic Church. In it, he explores the Church's power, its historic schisms, and the papacy. (short review from www.alibris.com)
"In 1979 I then had personal experience of the Inquisition under another pope. My permission to teach was withdrawn by the church, but nevertheless I retained my chair and my institute (which was separated from the Catholic faculty). For two further decades I remained unswervingly faithful to my church in critical loyalty, and to the present day I have remained professor of ecumenical theology and a Catholic priest in good standing. I affirm the papacy for the Catholic Church, but at the same time indefatigably call for a radical reform of it in accordance with the criterion of the gospel." (from Introduction)
