In the pre-German age Europe was for the most part inhabited by Celtic races. In Britain, Spain and Gaul, however, these were subjugated by the Roman forces and Romanized, whereas in northern, eastern and middle Europe they were oppressed, exterminated or Germanized by the Germans. In its victorious march through Europe, Christianity met with Celtic races of unmixed nationality only in Ireland and Scotland, for even among the neighbouring Britons the Celtic nationality was already blended with the Roman. Only in a very restricted field, therefore, could the church first of all develop itself according to the Celtic mode of culture. But here, with a wonderful measure of independence, missionary operations were so energetically prosecuted that for a long time it seemed as if the greater part of the opposite continent with its German population was to be its prey, until at last the Romish church would be driven out of its own home as well as out of its hopeful mission fields (§ 77).—Even in pre-Christian times a second and more powerful immigration from the East had begun to pour over Europe. The various Germanic groups of tribes now presented themselves, followed by other warlike races, Huns, Slavs, Magyars, etc., alternately driving and being driven. The Germans first came into contact with Christian elements in the second half of the 3rd century, and toward the end of the 5th a whole series of powerful German peoples are found professing the Christian faith, and each successive century far down into the Middle Ages brings always new trophies from these nations into the treasure-house of the church. It would certainly be wrong to ascribe these results to a national predisposition of the German churches and type of mind for Christianity. This cannot be altogether denied, but it did not predispose the German peoples to Christianity as it then was preached, but was first developed when this by other ways and means had found an entrance and only at the Reformation of the 16th century did it get full expression. For that predisposition was directed to the deepest and innermost sides of Christianity, for which the ecclesiastical institution of the times in its externalism had little appreciation; and the first task of the German spirit was to secure recognition of this reformatory principle.
§ 75.1. The Predisposition of the Germans for Christianity.—What we have been accustomed to hear about this subject is in part greatly exaggerated, in part sought for where its proper germ does not lie. The German mythology may indeed conceal many deep thoughts under the garb of legendary poetry which have some relation to Christian truth and afford evidence of the religious needs, the speculative gifts and the characteristic profundity of German thought, but this scarcely in a larger measure than in the Greek myths, philosophemes and mysteries.200 Much more suggestive of a predisposition to Christianity than such bright spots in the mythological system of the Germans are the special and distinguishing characteristics of the life of the German people. The fidelity of the vassal to his lord, transferred to Christ the heavenly king, constitutes the special core of Christianity. Besides, closely connected therewith, the love of battle and faithfulness in battle for and with the hereditary or elected chief found a parallel in the struggles and victories of the Christian life. Further, the Germans’ noble love of freedom, sanctified by the Gospel, afforded form and expression for the glorious freedom of the children of God. And finally, the spirituality of the Germans’ worship, praised even by Tacitus, who says that they nec cohibere parietibus Deos, neque in ullam humani oris speciem adsimulare, ex magnitudine cœlestium arbitrantur, predisposed them in favour of the worshipping of God in spirit and in truth.
§ 75.2. What is of most significance, however, for understanding the almost unopposed Adoption of Christianity by so many German races is the slight hold that their heathen religion had upon them at that time. It is essentially characteristic of heathenism as the religion of nature that it can flourish only on its native soil. German paganism, however, had been uprooted by its transplantation to European soil and had, amid the movements of peoples during the first centuries after their migration, never quite struck root in the new ground. In the later centuries, when it had long enough time for doing so, e.g. among the Frisians, Saxons, Danes, it offered an incomparably more resolute resistance. Again, rapid conversion will be furthered or hindered according as the new home is one where already from Roman times Christian institutions existed or even had existed, or is one where the old primitive heathenism still prevailed. Only in the latter case could German paganism develop its full power and strike its roots deeply and feel at home upon the new soil; whereas in the other case, the higher culture and spiritual power of Christianity, even where it had been vanquished by the barbarians, disturbed the even tenour and naïvete of the genuinely pagan course of development. The circumstance also deserves mention, that the marriage of heathen princes with Christian princesses frequently secured their conversion along with that of their subjects. In the narrower circles of the home, the family, the tribe, innumerable instances of the same sort of thing repeatedly occurred. There is something specially Germanic, in the prominent position which German feeling had assigned to the wife: Inesse quin etiam, says Tacitus, sanctum aliquid et providum putant; nec aut consilia earum adspernantur, aut responsa negligunt.201
§ 75.3. Mode of Conversion in the Church of these Times.—Apart from the too frequent practice of Christian rulers to secure conversions by the sword, baptism and conversion were commonly regarded as an opus operatum, and whole crowds of heathens without any knowledge of saving truth, with no real change of heart and mind, were received into the church by baptism. No one can approve this. But it must be admitted that only in this way could striking and rapid results have been reached; that indeed in the stage of childhood, in which the Germans then were, it had a certain measure of justification. By the history even of its attack upon German paganism an entirely different career of conflict and victory was marked out to Christianity than that through which it had to pass in its conquests of Græco-Roman paganism. In this latter case it had to confront a high form of civilization which had outlived its powers and had lost itself in its own perplexities, which for a thousand years had proved in its civilization and history a παιδαγωγὸς εἰς Χριστόν. All this was wanting to the Germans. If the Roman world might be compared to a proselyte who in ripe, well proved and much experienced maturity receives baptism, the conversion of the Germans may be compared to the baptism of children.—Gregory the Great had at first directed the missionaries to the Anglo-Saxons (§ 77, 4) to destroy the idol temples of converted heathens. But further reflection convinced him that it was better to transform them into Christian churches, and now he laid it down as a maxim in Roman Catholic missions that pagan forms of worship and places of worship which were capable of modification to Christian uses should be carefully preserved and respected: “Nam duris mentibus simul omnia abscindere impossibile esse dubium non est, quia et is qui summum locum ascendere nititur, gradibus vel passibus, non autem saltibus, elevatur.” It was a fateful, two-edged word, which led Catholic missions to a brilliant outward success, but has saturated the Catholic worship and life with a pagan leaven, which works in it powerfully down to the present day.
