Before proceeding further in our investigation of the origin and course of the Reformation, it may be well to recall how far we have already advanced. We started from the fact that a Reformation of the Irish Church was actually accomplished in the twelfth century, and we proceeded to look for the causes which may have brought it about. We have found that the first of these was the revival of learning consequent on the cessation of the ravages of the Norsemen. We have noted also the restoration at the same period of communication between Ireland and the rest of Europe—the coming of students to the Irish schools, and the wanderings of Irish scholars in other lands. We have seen that the establishment of the Danish dioceses gave to the Irish a model of diocesan episcopacy, and that among the Irish-born bishops of those dioceses there were men capable of leading a Reform movement. And we have learned that Lanfranc and Anselm, through their relation with the Danish dioceses, found means to induce the more conspicuous civil and religious leaders of the Celtic population to undertake the work of reconstituting the Church. Finally, we have been able to name some persons who might be expected to take a prominent place in the early stages of the Reformation. They are Gilbert of Limerick, Malchus of Waterford, O'Dunan of Meath, and the princes of the O'Brien family. The best proof that we have rightly conceived the origin of the movement will come before us when we study the share which these persons severally had in promoting it.
We must now trace, as far as it can be done, the first steps in the process by which, under the influences which I have indicated, the Church of Ireland passed from its older to its later hierarchical system.
The earliest attempt to give concrete form to the principles of the Reformers seems to have been made in the Kingdom of Meath, about the year 1100. But the primary evidence for the fact is of much later date. There are extant some constitutions of Simon Rochfort, bishop of Meath, put forth at a synod of his diocese held at the monastery of SS. Peter and Paul at Newtown, near Trim, in 1216. The first of them recites an ordinance of the papal legate, Cardinal John Paparo, at the Council of Kells in 1152, which is of great importance.
Paparo ordered that as the bishops of the weaker sees died off, arch-priests, or, as we call them, rural deans, should succeed to their place, and take charge of the clergy and people within their borders.[30]
The inference which this enactment suggests is that the weaker sees to which it refers were the centres of small dioceses, which Paparo desired to be converted into rural deaneries. In accordance with the ordinance of Paparo, Rochfort's synod enjoined that rural deans should be placed in the five sees of Trim, Kells, Slane, Skreen and Dunshaughlin, each of whom should supervise the churches in his own deanery. These, with Clonard, which had long been the see of Rochfort's diocese, are six of the twelve rural deaneries into which the present diocese of Meath is divided.[31] I conclude that they, and probably the remaining six, coincided more or less closely with dioceses ruled by bishops in the first half of the twelfth century.[32]
Let us now call to our aid a much earlier witness. The annalists inform us that in the year 1111 there was an assembly at Usnagh in Meath. It decreed that "the parishes[33] of Meath" should be equally divided between the bishops of Clonmacnoise and Clonard. We may infer that Clonmacnoise and Clonard, two of the present rural deaneries, were then dioceses. It is not likely that the dioceses of Meath would have been formed into two groups, each to constitute the diocese of a bishop who had already no diocese of his own. But however that may be, we have here proof that before 1111 Meath had been parted into a number of small dioceses ruled by bishops.
If the question be asked, By whose authority or influence this division of Meath into dioceses was made? I can suggest no one more likely than Máel Muire Ua Dunáin, the "bishop of Meath" to whom reference has already been made.[34] He was a Meath man, and probably bishop of Clonard: he was an ecclesiastic of great repute, especially in the north; and he was a devoted adherent of the Reform movement. His action, if indeed it was his, was premature and ill-advised. As we shall see, his work had to be slowly undone. But it is remarkable, as the first attempt known to us to establish diocesan episcopacy among the Irish. I shall have more to say about it hereafter; but now I must follow the main stream of events.
Gilbert,[35] the first bishop of Limerick, as has already been noted, was an Irishman. Indeed, we may venture to describe him as one of the most remarkable Irishmen of his time, in spite of the fact that the Annals pass him by in almost complete silence. He was at any rate a staunch supporter, or, as we should rather say, the leader of the Reformation movement in its earliest course. In a letter written in 1107 Anselm exhorted him, in virtue of their mutual friendship, to make good use of his episcopal office by correcting that which was amiss, and planting and sowing good customs, calling to aid him in the work his king (Murtough O'Brien), the other Irish bishops, and all whom he could persuade.[36] That, assuredly, Gilbert was forward to do.
No sooner had he taken possession of his see than he began to organize a diocese. Its boundaries seem to have been fixed with care. It was exactly co-extensive with the modern diocese of Limerick, except on the north, where it stretched across the Shannon and included part of the present diocese of Killaloe.[37] Moreover he made the Church of St. Mary his Cathedral Church; indeed it is not unlikely that he built it to serve that purpose.
A few years later he was appointed Legate of the Holy See. It is manifest that his new office gave him a unique opportunity of moulding the fortunes of the Irish Church. In Ireland Gilbert was now virtually the chief prelate and head of the Church. He was the representative and embodiment of the authority of the Holy See. The whole Romanizing party would naturally circle round him as their leader, and many waverers would be attracted to the new movement in the Irish Church, by the claim which he could make to speak in the name of the head of the Church Catholic.
