On the Feast of the Nativity, IV.
I. The Incarnation fulfils all its types and promises.
The Divine goodness, dearly beloved, has indeed always taken thought for mankind in divers manners, and in many portions, and of His mercy has imparted many gifts of His providence to the ages of old; but in these last times has exceeded all the abundance of His usual kindness, when in Christ the very Mercy has descended to sinners, the very Truth to those that are astray, the very Life to those that are dead: so that Word, which is co-eternal and co-equal with the Father, might take our humble nature into union with His Godhead, and, being born God of God, might also be born Man of man. This was indeed promised from the foundation of the world, and had always been prophesied by many intimations of facts and words 764 : but how small a portion of mankind would these types and fore-shadowed mysteries have saved, had not the coming of Christ fulfilled those long and secret promises: and had not that which then benefited but a few believers in the prospect, now benefited myriads of the faithful in its accomplishment. Now no longer then are we led to believe by signs and types, but being confirmed by the gospel story we worship that which we believe to have been done; the prophetic lore 765 assisting our knowledge, so that we have no manner of doubt about that which we know to have been predicted by such sure oracles. For hence it is that the Lord says to Abraham: “In thy seed shall all nations be blessed 766 :” hence David, in the spirit of prophecy, sings, saying: “The Lord swore truth to David, and He shall not frustrate it: of the fruit of thy loins will I set upon thy seat 767 ;” hence the Lord again says through Isaiah: “behold a virgin shall conceive in her womb, and shall bear a Son, and His Name shall be called Emmanuel, which is interpreted, God with us 768 ,” and again, “a rod shall come forth from the root of Jesse, and a flower shall arise from his root 769 .” In which rod, no doubt the blessed Virgin Mary is predicted, who sprung from the stock of Jesse and David and fecundated by the Holy Ghost, brought forth a new p. 135 flower of human flesh, becoming a virgin-mother.
II. The Incarnation was the only effective remedy to the fall.
Let the righteous then rejoice in the Lord, and let the hearts of believers turn to Gods praise, and the sons of men confess His wondrous acts; since in this work of God especially our humble estate realizes how highly its Maker values it: in that, after His great gift to mankind in making us after His image, He contributed far more largely to our restoration when the Lord Himself took on Him “the form of a slave.” For though all that the Creator expends upon His creature is part of one and the same Fatherly love, yet it is less wonderful than man should advance to divine things than that God should descend to humanity. But unless the Almighty God did deign to do this, no kind of righteousness, no form of wisdom could rescue any one from the devils bondage and from the depths of eternal death. For the condemnation that passes with sin from one upon all would remain, and our nature, corroded by its deadly wound, would discover no remedy, because it could not alter its state in its own strength. For the first man received the substance of flesh from the earth, and was quickened with a rational spirit by the in-breathing of his Creator 770 , so that living after the image and likeness of his Maker, he might preserve the form of Gods goodness and righteousness as in a bright mirror. And, if he had perseveringly maintained this high dignity of his nature by observing the Law that was given him, his uncorrupt mind would have raised the character even of his earthly body to heavenly glory. But because in unhappy rashness he trusted the envious deceiver, and agreeing to his presumptuous counsels, preferred to forestall rather than to win the increase of honour that was in store for him, not only did that one man, but in him all that came after him also hear the verdict: “earth thou art, and unto earth shalt thou go 771 ;” “as in the earthy,” therefore, “such are they also that are earthy 772 ,” and no one is immortal, because no one is heavenly.
III. We all become partakers in the Birth of Christ, by the re-birth of baptism.
And so to undo this chain of sin and death, the Almighty Son of God, that fills all things and contains all things, altogether equal to the Father and co-eternal in one essence from Him and with Him, took on Him mans nature, and the Creator and Lord of all things deigned to be a mortal: choosing for His mother one whom He had made, one who, without loss of her maiden honour, supplied so much of bodily substance, that without the pollution of human seed the New Man might be possessed of purity and truth. In Christ, therefore, born of the Virgins womb, the nature does not differ from ours, because His nativity is wonderful. For He Who is true God, is also true man: and there is no lie in either nature. “The Word became flesh” by exaltation of the flesh, not by failure of the Godhead: which so tempered its power and goodness as to exalt our nature by taking it, and not to lose His own by imparting it. In this nativity of Christ, according to the prophecy of David, “truth sprang out of the earth, and righteousness looked down from heaven 773 .” In this nativity also, Isaiahs saying is fulfilled, “let the earth produce and bring forth salvation, and let righteousness spring up together 774 .” For the earth of human flesh, which in the first transgressor, was cursed, in this Offspring of the Blessed Virgin only produced a seed that was blessed and free from the fault of its stock. And each one is a partaker of this spiritual origin in regeneration; and to every one when he is re-born, the water of baptism is like the Virgins womb; for the same Holy Spirit fills the font, Who filled the Virgin, that the sin, which that sacred conception overthrew, may be taken away by this mystical washing.
IV. The Manichæans, by rejecting the Incarnation, have fallen into terrible iniquities.
In this mystery, dear beloved, the mad error of the Manichæans has no part, nor have they any partnership in the regeneration of Christ, who say that He was corporeally born of the Virgin Mary: so that, as they do not believe in His real nativity, they do not accept His real passion either; and, not acknowledging Him really buried, they reject His genuine resurrection. For, having entered on the perilous path of their abominable dogma, where all is dark and slippery, they rush into the abyss of death over the precipice of falsehood, and find no sure ground on which to rest; because, besides all their other diabolical enormities, on the very chief feast of Christs worship, as their latest confession has made manifest 775 , they revel in bodily as well as mental pollution, losing their own modesty as well as the purity of their Faith; so that they p. 136 are found to be as filthy in their rites as they are blasphemers in their doctrines.
V. Other heresies contain some portion of truth, but the Manichæans contain none whatever.
Other heresies, dearly beloved, although they are all rightly to be condemned in their variety, yet have each in some part of them that which is true. Arius, in laying down that the Son of God is less than the Father and a creature, and in thinking that the Holy Spirit was like all else made by the same (Father), has lost himself in great blasphemy; but he has not denied the eternal and unchangeable Godhead in the essence of the Father, though he could not see it in the Unity of the Trinity. Macedonius was devoid of the light of the Truth when he did not receive the Godhead of the Holy Spirit, but he did acknowledge one power and the same nature in the Father and the Son. Sabellius was plunged into inextricable error by holding the unity of substance to be inseparable in the Father, Son and Holy Spirit, but granted to a singleness of nature what he should have attributed to an equality of nature 776 , and because he could not understand a true Trinity, he believed in one and the same person under a threefold appellation. Photinus, misled by his mental blindness, acknowledged in Christ true man of our substance, but did not believe Him born God of God before all ages, and so losing the entirety of the Faith, believed the Son of God to have taken on Him the true nature of human flesh in such a way as to assert that there was no soul in it, because the Godhead Itself took its place 777 . Thus, if all the errors which the catholic Faith has anathematized are recanted, something is found in one after another which can be separated from its damnable setting. But in the detestable dogma of the Manicheans there is absolutely nothing which can be adjudged tolerable in any degree.
VI. Christians must cling to the one Faith and not be led astray.
But you, dearly beloved, whom I address in no less earnest terms than those of the blessed Apostle Peter, “a chosen race, a royal priesthood, a holy nation, a people for Gods own possession 778 ,” built upon the impregnable rock, Christ, and joined to the Lord our Saviour by His true assumption of our flesh, remain firm in that Faith, which you have professed before many witnesses, and in which you were reborn through water and the Holy Ghost, and received the anointing of salvation, and the seal of eternal life 779 . But “if any one preach to you any thing beside that which you have learnt, let him be anathema 780 :” refuse to put wicked fables before the clearest truth, and what you may happen to read or hear contrary to the rule of the catholic and Apostolic creed, judge it altogether deadly and diabolical. Be not carried away by their deceitful keepings of sham and pretended fasts which tend not to the cleansing, but to the destroying of mens souls. They put on indeed a cloke of piety and chastity, but under this deceit they conceal the filthiness of their acts, and from the recesses of their ungodly heart hurl shafts to wound the simple; that, as the prophet says, “they may shoot in darkness at the upright in heart 781 .” A mighty bulwark is a sound faith, a true faith, to which nothing has to be added or taken away: because unless it is one, it is no faith, as the Apostle says, “one Lord, one faith, one baptism, one God and Father of all, who is above all, and through all, and in us all 782 .” Cling to this unity, dearly beloved, with minds unshaken, and in it “follow after” all “holiness 783 ,” in it carry out the Lords commands, because “without faith it is impossible to please God 784 ,” and without it nothing is holy, nothing is pure, nothing alive: “for the just lives by faith 785 ,” and he who by the devils deception loses it, is dead though living, because as righteousness is gained by faith, so too by a true faith is eternal life gained, as says our Lord and Saviour. And this is life eternal, that they may know Thee, the only true God, and Jesus Christ, whom Thou hast sent 786 . May He make you to advance and persevere to the end, Who lives and reigns with the Father and the Holy Spirit, for ever and ever. Amen.
