The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 135
The Sentence pronounced by Patrick on Moccheus.
And after some days, while Moccheus heard the Book of Genesis read before him, wherein he is told that the patriarchs before the Flood lived for nine hundred years and more, and that after the Flood many lived for three hundred years, he did not readily believe in the sacred history; for he said that this tabernacle of clay, the human body, of flesh so weak, covered with skin, and framed with bones and sinews, could in no wise so long endure. The which when Saint Patrick observed, he came unto him, that with true reason he might drive all such scruples from his mind; for he said that the whole canonical Scripture was dictated and written by the finger of God, and therefore should in no wise be derogated or disbelieved; inasmuch as it was not more difficult for the Creator of all things to extend the life of man unto a thousand years, if so he willed, than unto one day, as according to the Psalmist: A thousand years in thy sight are but as yesterday, which is passed. But even on these things Moccheus still doubting, the saint thus pronounced, or rather prophesied: "Since thou disbelievest the Holy Scriptures, by thine own experience shalt thou prove the truth of its records; for even to the length of three hundred years shall thy life be prolonged, nor until that time is passed shalt thou enter into the joy of the Lord." And Moccheus afterward repented him of his want of faith, but the sentence pronounced by the Holy Spirit through the mouth of Patrick could not be revoked. And he lived for the space of three hundred years; and then paying the debt of nature, and shining in virtues and in miracles, at length he passed out of the world unto Christ.
