In this disputation this venerable Father shews that when the Lord says "his own" he means the will of his humanity, and when he says not to do "his own will," he teaches us not chiefly to seek our own wills but that through obedience we should submit our wills to the Divine Will. From all which it is evident that he had a human will by which he obeyed his Father, and that he had in himself this same human will immaculate from all sin, as true God and man. Which thing St. Ambrose also thus treats of in his explanation of St. Luke the Evangelist.
[After this follows a catena of Patristic quotations which I have not thought worth while to produce in full. After St. Ambrose he cites St. Leo, then St. Gregory Nazianzen, then St. Augustine. (L. & C., col. 647.)]
From which testimonies it is clear that each of those natures which the spiritual Doctor has here enumerated has its own natural property, and that to each one a will ought to be assigned. For an angelic nature cannot have a divine or a human will, neither can a human nature have a divine or an angelic will. For no nature can have anything or any motion which pertains to another nature but only that which is naturally given by creation. And as this is the truth of the matter it is most certainly clear that we must needs confess that in our Lord Jesus Christ there are two natures and substances, to wit, the Divine and human, united in his one subsistence or person, and that we further confess that there are in him two natural wills, viz.: the divine and the human, for his divinity so far as its nature is concerned could not be said to possess a human will, nor should his humanity be believed to have naturally a divine will: And again, neither of these two substances of Christ must be confessed as being without a natural will; but his human will was lifted up by the omnipotency of his divinity, and his divine will was revealed to men through his humanity. Therefore it is necessary to refer to him as God such things as are divine, and as man such things as are human; and each must be truly recognized through the hypostatic union of the one and the same our Lord Jesus Christ, which the most true decree of the Council of Chalcedon sets forth--[Here follows citation.] This same thing also the holy synod which was gathered together in Constantinople in the time of the Emperor Justinian of august memory, teaches in the vii^th. chapter of its definitions. [Here follows the citation.] Moreover it is necessary that we should faithfully keep what those Venerable Synods taught, so that we never take away the difference of natures as a result of the union, but confess one Christ, true and perfect God and also true and perfect man, the propriety of each nature being kept intact. Wherefore, if in no respect the difference of the natures of our Lord Jesus Christ has been taken away, it is necessary that we preserve this same difference in all its proprieties. For whoso teaches that the difference is in no respect to be taken away, declares that it must be preserved in all things. But when the heretics and the followers of heretics say that there is but one will and one operation, how is this difference recognized? Or where is the difference which has been defined by this holy Synod preserved? While if it is asserted that there is but one will in him (which is absurd), those who make this assertion must needs say that that will is either human or divine, or else composite from both, mixed and confused, or (according to the teaching of all heretics) that Christ has one will and one operation, proceeding from his one composite nature (as they hold). And thus, without any doubt, the difference of nature is destroyed, which the holy synods declared to be preserved in all respects even after the admirable union. Because, though they taught that Christ was one, his person and substance one, yet on account of the union of the natures which was made hypostatically, they likewise decreed that we should clearly acknowledge and teach the difference of those natures which were united in him, after the admirable union. Therefore if the proprieties of the natures in the same our one Lord Jesus Christ were preserved on account of the difference [of the natures], it is congruous that we should with full faith confess also the difference of his natural wills and operations, in order that we may be shown to have followed in all respects their doctrine, and may admit into the Church of Christ no heretical novelty.
And although there exist numerous works of the other holy Fathers, nevertheless we subjoin to this our humble exposition a few testimonies out of the books which are in Greek, for the sake of fastidiousness.
[Here follows a catena of passages from the Greek fathers, viz.: St. Gregory Theologus, St. Gregory Nyssen, St. John bishop of Constantinople, St. Cyril, bishop of Alexandria. (L. & C., col. 654.)]
From these truthful testimonies it is also demonstrated that these venerable fathers predicated in the one and the same Lord Jesus Christ two natural wills, viz.: a divine and a human, for when St. Gregory Nazianzen says, "The willing of that man who is understood to be the Saviour," he shows that the human will of the Saviour was deified through its union with the Word, and therefore it is not contrary to God. So likewise he proves that he had a human, although deified will, and this same he had (as he teaches in what follows) as well as his divine will, which was one and the same with that of the Father. If therefore he had a divine and a deified will, he had also two wills. For what is divine by nature has no need of being deified; and what is deified is not truly divine by nature. And when St. Gregory Nyssen, a great bishop, says that the true confession of the mystery is, that there should be understood one human will and another a divine will in Christ, what does he bid us understand when he says one and another will, except that there are manifestly two wills?
[He next proceeds to comment upon the passage cited from St. John, then upon that from St. Cyril of Alexandria. After this follow quotations from St. Hilary, St. Athanasius, St. Denys the Areopagite, St. Ambrose, St. Leo, St. Gregory Nyssen, St. Cyril of Alexandria, which are next commented on in their order. He then proceeds: (L. & C., col. 662.)]
There are not lacking most telling passages in other of the venerable fathers, who speak clearly of the two natural operations in Christ, not to mention St. Cyril of Jerusalem, St. John of Constantinople, or those who afterwards conducted the laborious conflicts in defence of the venerable council of Chalcedon and of the Tome of St. Leo against the heretics from whose error the assertion of this new dogma has arisen: that is to say, John, bishop of Scythopolis, Eulogius, bishop of Alexandria, Euphræmius and Anastasius the elder, most worthy rulers of the church of Theopolis, and above all that emulator of the true and apostolic faith, the Emperor Justinian of pious memory, whose uprightness of faith exalted the Christian State as much as his sincere confession pleased God. And his pious memory is esteemed worthy of veneration by all nations, whose uprightness of faith was disseminated with praise throughout the whole world by his most august edicts: one of these, to wit, that addressed to Zoilus, the patriarch of Alexandria, against the heresy of the Acephali to satisfy them of the rectitude of the apostolic faith, we offer to your most tranquil Christianity, sending it together with this paper of our lowliness through the same carriers. But lest this declaration should be thought burdensome on account of its length, we have inserted in this declaration of our humility only a few of the testimonies of the Holy Fathers, especially [when writing to those] on whom the care and arrangement of the whole world as on a firm foundation are recognized to rest; since this is altogether incomparable and great, that the care of the whole Christian State being laid aside for a little out of love and zeal for true religion, your august and most religious clemency should desire to understand more clearly the doctrine of apostolical preaching. For from the different approved fathers the truth of the Orthodox faith has become clear although the treatment is short. For the approved fathers thought it to be superfluous to discourse at length upon what was evident and clear to all; for who, even if he be dull of wit, does not perceive what is evident to all? For it is impossible and contrary to the order of nature that there should be a nature without a natural operation: and even the heretics did not dare to say this, although they were, all of them, hunting for human craftiness and cunning questions against the orthodoxy of the faith, and arguments agreeable to their depravities.
How then can that now be asserted which never was said by the holy orthodox fathers, nor even was presumptuously invented by the profane heretics, viz.: that of the two natures of Christ, the divine and the human, the proprieties of each of which are recognized as being preserved in Christ, that anyone in sound mind should declare there was but one operation? Since if there is one, let them say whether it be temporal or eternal, divine or human, uncreated or created: the same as that of the Father or different from that of the Father. If therefore it is one, that one and the same must be common to the divinity and to the humanity (which is absurd), therefore while the Son of God, who is both God and man, wrought human things on earth, likewise also the Father worked with him according to his nature (naturaliter, phusikos); for what things the Father doeth these the Son also doeth likewise. But if (as is the truth) the human acts which Christ did are to be referred to his person alone as the Son, which is not the same as that of the Father; in one nature Christ worked one set of works, and in the other another, so that according to his divinity the Son does the same things that the Father does; and likewise according to his humanity, what things are proper to the manhood, those same, he as man, did because he is truly both God and man. For which reason we rightly believe that that same person, since he is one, has two natural operations, to wit, the divine and the human, one uncreated, and the other created, as true and perfect God and as true and perfect man, the one and the same, the mediator between God and men, the Lord Jesus Christ. Wherefore from the quality of the operations there is recognized a difference void of offence (aproskopos ) of the natures which are joined in Christ through the hypostatic union. We now proceed to cite some passages from the execrable writings of the heretics hated of God, [330] whose words and sayings we equally abominate, for the demonstration of those things which our inventors of new dogma have followed teaching that in Christ there is but one will and one operation.
[Then follow quotations from Apollinaris, Severus, Theodosius of Alexandria. (L. & C., col. 667.)]
Behold, most pious lords and sons, by the testimonies of the holy Fathers, as by spiritual rays, the doctrine of the Catholic and Apostolic Church has been illustrated and the darkness of heretical blindness, which is offering error to men for imitation, has been revealed. Now it is necessary that the new doctrine should follow somebody, and by whose authority it is supported, we shall note.
[Here follow quotations from Cyrus of Alexandria, Theodore of Pharon, Sergius of Constantinople, Pyrrhus, Paulus his successor, Peter his successor. (L. & C., col. 670.)]
Let then your God-founded clemency with the internal eye of discrimination, which for the guidance of the Christian people you have been deemed worthy to receive by the Grace of God, take heed which one of such doctors you think the Christian people should follow, the doctrine of which one of these they should embrace so as to be saved; for they condemn all, and each one of them the other, according as the various and unstable definitions in their writings assert sometimes that there is one will and one operation, sometimes that there is neither one nor two operations, sometimes one will and operation, and again two wills and two operations, likewise one will and one operation, and again neither one, nor two, and somebody else one and two.
Who does not hate, and rage against, and avoid such blind errors, if he have any desire to be saved and seek to offer to the Lord at his coming a right faith? Therefore the Holy Church of God, the mother of your most Christian power, should be delivered and liberated with all your might (through the help of God) from the errors of such teachers, and the evangelical and apostolic uprightness of the orthodox faith, which has been established upon the firm rock of this Church of blessed Peter, the Prince of the Apostles, which by his grace and guardianship remains free from all error, [that faith I say] the whole number of rulers and priests, of the clergy and of the people, unanimously should confess and preach with us as the true declaration of the Apostolic tradition, in order to please God and to save their own souls.
