Peter. These things as well as the inner meaning of the history created by the Papacy can be best understood if one is really aware of the poles between which life moves within and without the Church. It then becomes evident that Christianity would never later on con- front opposites more dissonant, or a tension more violent, than it faced in the days when it was first seeking a pathway through the world.
The books of the New Testament agree in affirming a strong re- solve to renew the foundations of the contemporary world. And yet when Paul and the author of the Apocalypse speak of political things they are as disparate as are a peaceful mission and a charge across battlefields. Both points of view continue to find expression through- out the first three centuries of Christendom. Heathen contemporar- ies, even the best and most mature among them, regard the new religion as rebellion, collapse and social peril of the gravest kind.

Needed are heralds and executors of His law. A visible likeness must be found for His invisible majesty; and His reign has need of an authorized viceroy. When the conquering Church accepted Empire and Emperor as its models, k
