We are told by a very ancient authority[72] that the Saint was accompanied to Ireland by a great number of holy bishops and priests and deacons, and other youths in minor orders whom he had himself ordained for the Irish Mission. They were Britons, Franks, and Romans, the latter term simply meaning that some amongst them enjoyed the rights of Roman citizenship. Many of them were his own blood relations, like Sechnall or Secundinus, the son of Patrick's sister, Darerca. Others, like Auxilius and Iserninus, are said to have been sent by Germanus of Auxerre to aid St. Patrick in preaching to the Irish. These two prelates, however, though ordained with St. Patrick, did not come to Ireland for some time after the arrival of St. Patrick. Iserninus founded his church at Kilcullen in the co. Kildare, and Auxilius founded Killossy, in the barony of Naas, which takes its name Cill-Usailli (Gen. of Ausaille) from that Saint. The names of these two bishops are chiefly memorable in connection with a celebrated Synod--the first held in Ireland--which is commonly called the Synod of Patrick, Auxilius, and Iserninus. Having been ordained Priests, if not Bishops, on the same day with St. Patrick himself, these two prelates seem to have enjoyed a certain kind of co-ordinate authority with Patrick, but still in subjection to his primatial jurisdiction. The name of Secundinus is not mentioned in connection with this Synod, which was held A.D. 447 or 448, either because he was already dead, or did not possess independent jurisdiction as one of the original episcopal founders of the Irish Church. We cannot now enter into the question how far all the Canons attributed to St. Patrick in the great collections published by several writers are genuine, or merely circulated under his name with a view to lend them greater authority.[73] Those attributed, however, to the Synod of Patrick, Auxilius, and Iserninus are commonly regarded as authentic,[74] and indeed bear intrinsic evidence that they were framed at a time when paganism was yet common in Ireland.
