The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 37
Of the Holy Mochna.
And there was a youth of virtuous disposition named Mochna, and he was a swine-herd whom Saint Patrick had met near the town of Ereattan while he was preaching in those parts, and to him, the Spirit having revealed that he was destined to be a vessel of election, did the saint preach the way of salvation. And the youth, even at his first preaching, believed; and Patrick, when he had baptized him, taught unto him the alphabet, and, having blessed him, sent him to be instructed in learning, and went his way. But the youth, through the divine grace, learned in one month the whole Psaltery, and, before the year had ended, arrived he at the knowledge of the Holy Scriptures. And after some time Patrick returned to the aforementioned village, and Mochna met him there. And while sitting together, they conversed on holy things; behold, a staff sent from heaven fell between them, and the head thereof rested on the bosom of Patrick, and the point thereof on the bosom of Mochna. And the saint, gratulating the youth on the gift thus miraculously bestowed, said unto him: "Now, my best-beloved son, shalt thou know by this pastoral staff that the guardianship of souls will be committed unto thee." But he refusing and alleging his ignorance and the imperfection of his youth, the saint is reported thus to have said: "Seek not thou to excuse thyself for that thou art a boy, since unto all those parts whither the Lord sendeth thee shalt thou go; and what he commandeth unto thee, that shalt thou speak." Therefore through the several degrees did Patrick at length consecrate him a bishop, and placed him over the church of Edrum. And he profited much the church of God by his conversation and by his example, and, being renowned in virtues and in miracles, was called to heaven. And he was buried in that church wherein he had worthily served the Lord, and wherein, adorned with manifold miracles, he had accustomed himself to live in Christ. And the staff is in that church still preserved, and is called by the Irish "the flying staff." And as Saint Patrick had advanced this man from the care of swine unto the episcopate, a swine is yearly taken from that territory, and paid unto the church of Down.
