By calling his book the true story of the Vatican Council of 1870, Cardinal Manning (1808-1892) aimed at dissipating a dark cloud of fase notions. In its lucid simplicity and factuality his book remains the best concise account of what was debated and defined at Vatican I and of its importance for the Church in the modern world.
As Archbishop of Westminster, Manning, one of the foremost converts from Anglicanism, was in the very center of those debates. In fact, without him papal infallibility might not have come up for debate at Vatican I. Called by some of his antagonists "the devil of the council", he was a providential and prophetic voice there.
Manning's formulation of the alternative, "It is Rome or licence of thought and will," should seem particularly relevant in these decades of runaway social disintegration within which only Rome's voice remains clear, unbending, and consistent-in witness to its infallibility.
In the Introduction by Fr. Stanley L. Jaki, Cardinal Manning's book is put in the context of social as well as theological issues. Fr. Jaki, a world-renowned historian of science, is also widely known for his monograph, Les tendances nouvelles de l'ecclesiologie (reprinted during Vatican II), and his books on the papacy: And on this Rock: The Witness of One Land and Two Covenants and The Keys of the Kingdom: A Tool's Witness to Truth. He is an honorary member of the Pontifical Academy of Sciences and the recipient of the Templeton Prize for 1987.
