When Locke was writing his famous ‘Letters on Toleration,’ he was led to a consideration of the Patristic miracles by an argument which seems then to have been deemed very forcible, but which, as it belongs to a different ‘climate of opinion’ from our own, would now be regarded as both futile and irreverent. It was absolutely necessary, it was contended, under ordinary circumstances, for the well-being of Christianity, that it should be supported by persecution; that is to say, that the civil power should suppress its opponents. When Christianity was still unrecognised by government, it existed in an abnormal condition; the laws of nature were suspended in its favour, and continual miracles ensured its triumph. When, however, the conversion of Constantine placed the civil power at its disposal, the era of the supernatural was closed. The power of persecuting was obtained; and, therefore, the power of working miracles was withdrawn. The alliance between Church and State being instituted, Christianity had arrived at its normal and final position, and exceptional assistance had become unnecessary.173 This argument, the work of the theologians of Oxford, was not likely to stagger Locke; but the historical question which it opened was well calculated to arrest that keen and fearless intellect, so little accustomed to bow before unsupported authority, and at that very time engaged in the defence of toleration against the entire weight of ecclesiastical tradition. He appears to have consulted Sir Isaac Newton; for, in one of Newton's letters, we find a somewhat hesitating passage upon the subject. ‘Miracles,’ Newton wrote, ‘of good credit continued in the Church for about two or three hundred years. Gregorius Thaumaturgus had his name from thence, and was one of the latest who was eminent for that gift; but of their number and frequency I am not able to give you a just account. The history of those ages is very imperfect.’174 Locke does not appear to have adopted this view. In reply to the Oxford argument, he wrote a very remarkable passage, which did not, apparently, attract at the time the attention it deserved; but which, long afterwards, obtained an extremely conspicuous place in the discussion. ‘This, I think,’ he said, ‘is evident, that he who will build his faith or reasonings upon miracles delivered by Church historians, will find cause to go no further than the Apostles' time, or else not to stop at Constantine's, since the writers after that period, whose word we readily take as unquestionable in other things, speak of miracles in their time, with no less assurance than the Fathers before the fourth century; and a great part of the miracles of the second and third centuries stand upon the credit of the writers of the fourth.’175
After this time, the subject of the miracles of the Fathers seems to have slept until public attention was called to it by the well-known work of Middleton. That the ‘Free Inquiry’ was a book of extraordinary merit, that it displayed great eloquence, great boldness, and great controversial dexterity, and met with no opposition at all equal to its abilities, will scarcely be denied. But, in order to appreciate its success, we should consider, besides these things, the general character of the age in which it appeared. During the half century that elapsed between Locke and Middleton, many influences that it would be tedious to examine, but to which Locke himself by his philosophy most largely contributed, had profoundly modified the theology of England. The charm and fascination which the early Fathers exercised upon the divines of the previous century had quite passed away. The Patristic works fell rapidly into neglect, and the very few who continued to study them were but little imbued with their spirit. Nothing, indeed, could be more unlike the tone of the Fathers, than the cold, passionless, and prudential theology of the eighteenth century; a theology which regarded Christianity as an admirable auxiliary to the police force, and a principle of decorum and of cohesion in society, but which carefully banished from it all enthusiasm, veiled or attenuated all its mysteries, and virtually reduced it to an authoritative system of moral philosophy. There never had been a time when divines had such a keen dread of anything that appeared absurd or grotesque. The spirit that, in the previous century, had destroyed the belief in witchcraft, passed in its full intensity into their works. Common sense was the dominating characteristic of all they wrote. Generous sentiments, disinterested virtue, reverential faith, sublime speculations, had passed away. Every preacher was employed in showing that Christianity was in all respects perfectly in accordance with human reason, in eliminating or obscuring whatever could shock the feelings or offend the judgment, in representing religion as intended to refine and harmonise society, to embellish all the relations of life, to give a higher sanction to the dictates of human prudence, and to extend the horizon of that prudence beyond the grave. As a consequence of this state of mind, there was an increasing indisposition to accept miracles like those of the Fathers, which were not included in the evidences of Christianity, and a decreasing reverence for the writers on whose testimony they rest.
It was in the midst of this movement of thought, that Middleton published his great attack upon the Patristic miracles, and brought into clear relief both the difficulties and the importance of the subject. The writings of the Fathers contain numerous accounts of miracles which they alleged to have taken place in their own day and under their own notice, and which are of such a nature, and are related in such a manner, that it seems scarcely possible to avoid the conclusion that they had really taken place, or else that the Fathers deliberately palmed them off upon the credulity of their readers. The works of the first century that have come down to us are extremely scanty, and consist almost entirely of short epistles written without any historical or controversial purpose, for the encouragement or edification of believers; but even in this century, the martyrdom of St. Polycarp supplies an account which is clearly miraculous. Justin Martyr, who wrote very early in the second century, and it is said not more than fifty years after the death of St. John, distinctly asserts the continuance of miracles in his time, and from this date the evidence is ample and unbroken. The Protestant theory is, that miracles became gradually fewer and fewer, till they at last entirely disappeared. The historical fact is, that, generation after generation, the miraculous accounts became more numerous, more universal, and more extraordinary. ‘As far as the church historians can illustrate or throw light upon anything, there is not a single point in all history so constantly, explicitly, and unanimously confirmed by them all, as the continual succession of those powers through all ages, from the earliest father who first mentions them down to the time of the Reformation.’176 If, then, we gave even a general credence to the historical evidence upon the subject, we should be carried down, without pause or chasm, into the depths of the middle ages; and we should be compelled to admit, that what Protestants regard as the worst superstitions of the Church of Rome, were for centuries the habitual and special channels of supernatural favour. If again, in defiance of all the ordinary rules of historical criticism, we believed the assertions of the writers of the fourth century, but refused to credit the equally positive testimony of the writers of the ninth century, we should still be met by the same difficulty, though in a modified form. It may be contended, that the Fathers of the fourth century were not Roman Catholics; but it is quite certain that they were not, in the ordinary sense of the word, Protestants. It is quite certain that there existed among them many practices, forms of devotion, and doctrinal tendencies, which may not have been actually Roman Catholic, but which, at least, hung upon the extreme verge of Catholicism, which inevitably gravitated to it, and which were the germs and the embryos of mediæval theology. Now, it is precisely in connection with this department of their theology that the miraculous accounts are most numerous.
Such was the great difficulty of the question, regarded from the Protestant point of view. Middleton met it by an attack upon the veracity of the Fathers, which was so eloquent, so uncompromising, and so admirably directed, that all England soon rang with the controversy. He contended that the religious leaders of the fourth century had admitted, eulogised, and habitually acted upon principles that were diametrically
