The Catholic hierarchy with its enormous power at that moment, civil and economic as well as religious, was not the creator of such a spirit, it was only its leader. And in connection with that intense preoccupation of men’s minds, two factors already appear in the fourth century and are increasingly active through the fifth and sixth. The first is the desire that the living Church should be as free as possible; hence the Catholic Church and its ministers everywhere welcome the growth of local as against centralized power. They do so unconsciously but none the less strongly. The second factor is Arianism: to which I now return. Arianism, which both in its material success and in the length of its duration, as well as in its concept of religion, and the character of its demise, is singularly parallel to the Protestant movement of recent centuries, had sprung up as the official and fashionable Court heresy opposed to the orthodoxy of the Church. The Emperor’s Court did indeed at last—after many variations—abandon it, but a tradition survived till long after (and in many places) that Arianism stood for the “wealthy” and “respectable” in life. Moreover, of those barbarians who had taken service as auxiliaries in the Roman armies, the greater part (the “Goths,” for instance, as the generic term went, though that term had no longer any national meaning) had received their baptism into civilized Europe from Arian sources, and this in the old time of the fourth century when Arianism was “the thing.” Just as we see in eighteenth century Ireland settlers and immigrants accepting Protestantism as “gentlemanly” or “progressive” (some there are so provincial as still to feel thus), so the _Rex_ in Spain and the _Rex_ in Italy had a family tradition; they, and the descendants of their original companions, were of what had been the “court” and “upper class” way of thinking. They were “Arians” and proud of it. The number of these powerful heretics in the little local courts was small, but their irritant effect was great. It was the one great quarrel and problem of the time. No one troubled about race, but everybody was at white heat upon the final form of the Church. The populace felt it in their bones that if Arianism conquered, Europe was lost: for Arianism lacked vision. It was essentially a hesitation to accept the Incarnation and therefore it would have bred sooner or later a denial of the Sacrament, and at length it would have relapsed, as Protestantism has, into nothingness. Such a decline of imagination and of will would have been fatal to a society materially decadent. Had Arianism triumphed, the aged Society of Europe would have perished. Now it so happened that of these local administrators or governors who were rapidly becoming independent, and who were surrounded by a powerful court, _one_ only was not Arian.
