When we compare this single fact of Irish ecclesiastical history with what was then transpiring in Europe--the most insidious errors spreading throughout; the faith of many becoming unsettled, a general preparation for the social deluge which was impending and so soon to fall--we cannot but conclude that Ireland, in the midst of her misfortunes, was happy in being separated from the rest of the world. The breath of novelty could breathe no contagion on her shores. Happy even was she in not seeing her sons enlist in the army of the Cross, if the result of their victories was, to bring back from the Holy Land the Eastern corruption and the many heresies nestling there and settled, even around the sepulchre of our Lord, during so many ages of separation from the West and open communication with all the wild vagaries of Arabian, Persian, and Indian philosophies. Even in the midst of such a trial we believe that Ireland would have held steadfast to her faith, as she did later on when heresy came to her with compulsion or death; and this firmness of purpose, which the Irish have always manifested when the question was a change of religion, is worthy our consideration. For the facility with which some nations have, in the course of ages, yielded to the spirit of novelty, and the sturdy resistance opposed to it by others, is a subject that would repay investigation, but which we can only slightly touch upon. In ancient times the Greek mind, accustomed from the beginning to subtlety of argument, and easily carried away by a rationalism which was innate, offers a striking contrast to the steady traditional spirit of the Latin races in general. Except Pelagiaism and its cognate errors, all the great heresies which afflicted the Church during the first ten centuries, originated in the East; and the various sects catalogued by several of the Greek Fathers, as early as the second and third centuries, astonish the modern reader by the slender web on which their often ridiculous systems are spun, of texture strong enough, however, at the time to form the groundwork for making a disastrous impression on a large number of adherents. The infinity almost of philosophical systems in pagan Greece had prepared the way for the subsequent vagaries of heresy, and we must look to our own times, so prolific of absurd theories, in order to find a parallel to the incredible variety of dogmatic assertions among the Greek heresiarchs of early times.
