Peter’s Rock In Mohammed’s Flood From St. Gregory The Great to St. Leo III. Being the Seventh Volume of The Formation of Christendom By Thomas W. Allies, K.C.S.G. London: Burns & Oats, Ld. New York: Catholic Publication Society Co. 1890 PROLOGUE TO THE SEVEN VOLUMES OF THE FORMATION OF CHRISTENDOM. This work being from the beginning one in idea, I place here together the titles of the fifty-six chapters composing it. For each of these was intended to be complete in itself, so far as its special subject reached; but each was likewise to form a distinct link in a chain. The Church of God comes before the thoughtful mind as the vast mass of a kingdom. Its greatest deeds are but parts of something immeasurably greater. The most striking evidence of its doctrines and of its works is cumulative. Those who do not wish to let it so come before them often confine their interest in very narrow bounds of time and space. Thus I have known one, who thought himself a bishop, accept Wycliffe as the answer of a child to his question, Who first preached the Gospel in England? And not only this. They also seize upon a particular incident, or person, and so invest with extraordinary importance facts which they suppose, and which so conceived are convenient for their purpose, but in historical truth are anything but undisputed. In this tone of mind, or shortness of vision, that which is gigantic becomes puny, that which is unending becomes transient. The sequel and coherence of nations, the mighty roll of the ages spoken of by St. Augustine, are lost sight of. Again, in English-speaking countries alone more than two hundred sects call themselves Christian. Their enjoyment of perfect civil freedom and equality veils to them the horror of doctrinal anarchy, in virtue of which alone they exist. By this anarchy the very conception of unity as the corollary of truth is lost to the popular mind. But through the eight centuries of which I have treated, the loss of unity was the one conclusive test of falsehood, and the Christian Faith stood out to its possessors with the fixed solidity of a mountain range whose summit pierced the heaven.
