Leo [the bishop] to his [most] dear brother Flavian.
Having read your Affection's letter, the late arrival of which is matter of surprise to us, and having gone through the record of the proceedings of the bishops, we have now, at last, gained a clear view of the scandal which has risen up among you, against the integrity of the faith; and what at first seemed obscure has now been elucidated and explained. By this means Eutyches, who seemed to be deserving of honour under the title of Presbyter, is nowshown to be exceedingly thoughtless and sadly inexperienced, so that to him also we may apply the prophet's words, "He refused to understand in order to act well: he meditated unrighteousness on his bed." What, indeed, is more unrighteous than toentertain ungodly thoughts, and not to yield to persons wiser and more learned? But into this folly do they fall who, when hindered by some obscurity from apprehending the truth, have recourse, not to the words of the Prophets, not to the letters of the Apostles, nor to the authority of the Gospels, but to themselves; and become teachers of error, just because they have not been disciples of the truth. For what learning has he received from the sacred pages of the New and the Old Testament, who does not so much as understand the very beginning of the Creed? And that which, all the world over, is uttered by the voices of all applicants for regeneration, is still not grasped by the mind of this aged man. If, then, he knew not what he ought to think about the Incarnation of the Word of God, and was not willing, for the sake of obtaining the light of intelligence, to make laborious search through the whole extent of the Holy Scriptures, he should at least have received with heedful attention that general Confession common to all, whereby the whole body of the faithful profess that they "believe in God the Father Almighty, and in Jesus Christ Iris only Son our Lord, who was born of the Holy Ghost and the Virgin Mary." By which three clauses the engines of almost all heretics are shattered. For when God is believed to be both "Almighty" and "Father," it is proved that the Son is everlasting together with himself, differing in nothing from the Father, because he was born as "God from God," Almighty from Almighty, Coeternal from Eternal; not later in time, not inferior in power, not unlike him in glory, not divided from him in essence, but the same Only-begotten and Everlasting Son of an Everlasting Parent was "born of the Holy Ghost and the Virgin Mary." This birth in time in no way detracted from, in no way added to, that divine and everlasting birth; but expended itself wholly in the work of restoring man, who had been deceived; so that it might both overcome death, and by its power "destroy the devil who had the power of death." For we could not have overcome the author of sin and of death, unless he who could neither be contaminated by sin, nor detained by death, had taken upon himself our nature, and made it his own. For, in fact, he was "conceived of the Holy Ghost" within the womb of a Virgin Mother, who bore him as she hadconceived him, without loss of virginity.2 But if he (Eutyches) was not able to obtain a true conception from this pure fountain of Christian faith because by his own blindness he had darkened for himself the brightness of a truth so clear, he should have submitted himself to the Evangelist's teaching; and after reading what Matthew says, "The book of the generation of Jesus Christ, the Son of David, the Son of Abraham," he should also have sought instruction from the Apostle's preaching; and after reading in the Epistle to the Romans, "Paul, a servant of Jesus Christ, called an Apostle, separated unto the gospel of God, which he had promised before by theprophets in the Holy Scriptures, concerning his Son, who was made unto him of the seed of David according to the flesh," he should have bestowed some devout study on the pages of the Prophets; and finding that God's promise said to Abraham, "in thy seedshall all nations be blessed," in order to avoid all doubt as to the proper meaning of this "seed," he should have at-tended to the Apostle's words, "To Abraham and to his seed were the promises made. He saith not, `and to seeds,' as in the case of many, but as in the case of one, `and to thy seed,' which is Christ." He should also have apprehended with his inward ear the declaration of Isaiah, "Behold, a Virgin shall conceive and bear a Son, and they shall call his name Emmanuel, which is, being interpreted, God with us;" and should have read with faith the words of the same prophet, "Unto us a Child has been born, unto us a Son has been given, whose power is on his shoulder; and they shall call his name Angel of great counsel, Wonderful, Counsellor, Strong God, Prince of Peace, Father of the age to come." And he should not have spoken idly to the effect that the Word was in such a sense made flesh, that the Christ who was brought forth from the Virgin's womb had the form of a man, and had not a body really derived from his Mother's body. Possibly his reason for thinking that our Lord Jesus Christ was not of our nature was this-that the Angel who was sent to the blessed and ever Virgin Mary said, "The Holy Ghost shall come upon thee, and the power of rite Highest shall overshadow thee, and therefore also that holy thing which shall be born of thee shall be called the Son of God;" as if, because the Virgin's conception was caused by a divine act, therefore the flesh of him whom she conceived was not of the nature of her who con
