St. Patrick's Canons,[123] which even Usher admits to be genuine, contain the following passage. We give Usher's own translation, as beyond all controversy for correctness:--"Whenever any cause that is very difficult, and unknown unto all the judges of the Scottish nation, shall arise, it is rightly to be referred to the See of the Archbishop of the Irish (that is, of Patrick), and to the examination of the prelate thereof. But if there, by him and his wise men, a cause of this nature cannot easily be made up, we have decreed it shall be sent to the See Apostolic, that is to say, to the chair of the Apostle Peter, which hath the authority of the city of Rome." Usher's translation of St. Patrick's Canon is sufficiently plain, and evidently he found it inconveniently explicit, for he gives a "gloss" thereon, in which he apologizes for St. Patrick's Roman predilections, by suggesting that the saint was influenced by a "special regard for the Church of Rome." No doubt this was true; it is the feeling of all good Catholics; but it requires something more than a "special regard" to inculcate such absolute submission; and we can scarcely think even Usher himself could have gravely supposed, that a canon written to bind the whole Irish Church, should have inculcated a practice of such importance, merely because St. Patrick had a regard for the Holy See. This Canon was acted upon in the Synod of Magh-Lene, in 630, and St. Cummian attests the fact thus:--"In accordance with the canonical, decree, that if questions of grave moment arise, they shall be referred to the head of cities, we sent such as we knew were wise and humble men to Rome." But there is yet another authority for St. Patrick's Roman mission. There is an important tract by Macutenius, in the Book of Armagh. The authenticity of the tract has not, and indeed could not, be questioned; but a leaf is missing: happily, however, the titles of the chapters are preserved, so there can be no doubt as to what they contained. In these headings we find the following:-- "5. De ætate ejus quando iens videre Sedem Apostolicam voluit discere sapientiam." "6. De inventione Sancti Germani in Galiis et ideo non exivit ultra."
