Of the exact time at which Romish and Greek missionaries first went to Ireland we are not informed, but there is ample evidence going to prove that a regular hierarchy had been established in that island before the beginning of the fifth century, and that this religion which had been brought in through the efforts of missionaries from the East was, by the legendary writers of the later Christian Church, ascribed to Romish monks.
The Jealousy of the Romish priests, and the means employed by them to usurp the ecclesiastical authority of the Irish people, is shown in the history of their councils. The 5th canon of the Council of Ceale-hythe requires
"that none of Irish extraction be permitted to usurp to himself the sacred ministry in any one's diocese, nor let it be allowed such an one to touch anything which belongs to those of the holy order....; neither must he administer the eucharist to the people because we are not certain how or by whom he was ordained."
After quoting the above Ledwich queries thus: If St. Patrick had been a missionary of the Romish Church, would the Anglo-Saxon clergy have abjured the spiritual children of that see? In the year 670 Theodoret, Archbishop of Canterbury, decreed that they who were consecrated by Irish or British Bishops should be confirmed anew by Catholic ones.(154)

It is observed that as early as the fourth century A.D. there were three hundred bishops in Ireland, and to account for so large a number, it is declared that ignorant legendary writers had recourse to the fable of St. Patrick.
The remarkable "conversion" of the Irish to Romish Christianity, which it is said took place in the latter part of the fourth century or the beginning of the fifth, is to be explained by the fact that a number of Romish priests or monks which in later ages came to be designated as St. Patrick, claimed all the monasteries, bishops, and priests already there as a result of the remarkable power and pious zeal of this miracle-working saint. It is claimed that St. Patrick founded over three thousand monasteries, consecrated three hundred bishops, and ordained three thousand priests.
According to Ledwich and other writers, this St. Patrick was not heard of earlier than the ninth century A.D., and the legend concerning him "was not accepted until the twelfth century, at which time his miracles are set forth with great gusto."
Nothing, perhaps, which is recorded of this monk will go farther toward proving him a myth than the miracles ascribed to his saintship.
