This error confirms the truth of the hypothesis that under Muirchu’s account there lies a confusion between Patrick’s ordination to the diaconate and his elevation to the episcopate. The authentic record was that Amator ordained Patrick, Auxilius, and Iserninus (Patrick as deacon, the others perhaps as deacons also). When this was taken to refer to Patrick’s episcopal ordination, the association of Auxilius and Iserninus was still retained, and they were represented as accompanying Patrick.
The result of this criticism is in accordance with the general probability that Patrick had a continued connexion with one church—namely, the church of Auxerre, a connexion begun in the time of Amator and protracted in the time of Amator’s successor Germanus. And it suits the chronological data derived from the Confession (as shown above).
10. Evidence for Christianity in Ireland before St. Patrick
The circumstances which render it antecedently probable that Christianity should have penetrated to Ireland before A.D. 430 have been set forth in the introductory chapter. The positive evidence which shows that this occurred is Prosper’s notice of the mission of Palladius. It is supported by other evidence, but is in itself fully sufficient to establish the fact.
1. Prosper, Chron. s.a., 431:—
Ad Scottos in Christum credentes ordinatus a papa Caelestino Palladius primus episcopus mittitur.
It is important to observe that, if the express words in Christum credentes were absent, this record would establish the existence of Christian communities in Ireland. For neither Rome nor any other church would have ordained a bishop for Ireland unless there had been Christian communities there to be submitted to his authority. If all parts of Ireland had been still as entirely heathen as Scandinavia, a missionary might have been sent, but he would not have been a bishop.
Nothing can shake the inference from this record of Prosper, but some have attempted to weaken it by a statement in a later work of Prosper concerning Christianity in Ireland. In the contra Collatorem, written c. A.D. 437, Prosper, praising Celestine, says, et ordinato Scottis episcopo dum Romanam insulam studet servare catholicam fecit etiam barbaram Christianam (Migne, 51, 274). The expression is obviously rhetorical, and is not inconsistent with the statement in the Chronicle. It is quite possible that it is based on information which had reached Prosper of the progress of Christianity in the years 433-436; and, in a eulogy of Celestine, it was plausible to ascribe this success to his initiative in ordaining the first bishop. To infer that Prosper did not know of the death of Palladius would be unwarranted. Prosper was evidently interested in the mission of Palladius; he probably knew him personally, as there is reason to think that he was at Rome, engaged on ecclesiastical business with the Roman see, in the year 431; and these considerations render it highly improbable that he would not have been aware of his death. But it was not Prosper’s purpose to record the details of missionary work; he was merely concerned to notice, and not to minimise, what Celestine had done. The passage, therefore, must not be used to support the theory that Palladius and Patricius were one and the same person (Zimmer, Early Celtic Church, p. 33). On the other hand, it may be added to the other evidence which shows that Patrick was not ordained by Celestine; for in that case Prosper would not have omitted to notice that the Pope had ordained two bishops.
2. It has been generally overlooked that Patrick’s expression ad plebem nuper uenientem ad credulitatem (Conf. 368₉) suggests, in its most natural interpretation, a spreading of Christianity before his arrival. Otherwise we should expect primum rather than nuper.
3. If Pelagius, as Zimmer holds, was born in Ireland, we might consider it probable, almost certain, that he belonged to a Christian community, and thus we should have a confirmation of the existence of such communities before the end of the fourth century. But the evidence rather points, as I have shown (see note in [App. B, p. 296]), to Pelagius belonging to one of the Scottic settlements in western Britain. There is, however, another piece of evidence of the same kind. An Irishman, named Fith, better known under his ecclesiastical name of Iserninus, was with Patrick at Auxerre, and was ordained by Amator (see the evidence in [App. B, p. 297]).
