St. Patrick not only reformed the State Organization, he also established a Church Organization in Ireland. He knew well that it was not enough to preach, and baptize, and build churches; it was necessary, if his work was to endure, to train a native ministry, and organize the native Church in harmony with the institutions and character of the Celtic tribes in Ireland. It was a very difficult task; for the tribes were still very simple and primitive in their habits, and were moreover devotedly attached to the tribal institutions, which had come down to them from a remote antiquity. In accomplishing this task, which he did with perfect success, Patrick displayed singular firmness and prudence. Whenever there was question of principle, that is, of the truths of the Gospel and the teaching of the Church, he was, as might be expected, unyielding as the rock. But, on the other hand, he was no root-and-branch reformer; he dealt most tenderly with the usages and with the prejudices of the people. He utilized whatever was good in their existing habits and institutions, reformed what was imperfect, and lopped off what was evil. With druidism, for instance, he could make no terms. There could be no alliance between Christ and Belial; it must be utterly rooted out of the land. Not so with the Brehons, and the Brehon Code. He made no attempt to introduce the Roman Civil Law into Ireland; it would have been utterly unsuited to the tribal system. But he reformed the Brehon Code, and retained "all the judgments of a true nature, which the Holy Ghost had spoken through the mouths of the Brehons, and the just Poets of the men of Erin," thus winning over to his side that influential Order, who might otherwise have been arrayed against the propagation of the Gospel. In like manner he dealt with the Bards. In a spirit of consummate prudence, he sought to secure the aid of that powerful corporation for his infant Church, and succeeded in establishing a friendly alliance with the Arch-Poet of Erin. Dubthach Mac Ua Lugair held the twofold office of Chief Poet and Chief Brehon of Ireland, and St. Patrick utilized his influence and his services in both capacities. He was the working head of the Commission for the reformation of the Brehon Laws; but St. Patrick seems also to have secured his influence as Chief Poet in procuring eligible candidates for the sacred ministry from the schools of the Bards--the most lettered class in the community. It was thus the young poet, Fiacc of Sletty, was ordained by Patrick on the advice and at the suggestion of Dubthach. St. Patrick indeed had every reason to be grateful to the Arch-Poet; he was the first to believe in the Saint's teaching at Tara, and rose up to do him honour even against the king's command; he aided in reforming the laws; he gave his most promising young pupils for the service of the altar, including several of his own sons, who otherwise would doubtless have followed the profession of their father.
