Athanasius (~297-373 A.D.) "For being Word of the Father, and above all, He alone of natural fitness was both able to recreate everything, and worthy to suffer on behalf of all and to be ambassador for all with the Father" Incarnation of the Word chapter 7 (Nicene & Post-Nicene Fathers 2nd Series vol.4 p.40, See also Against the Heathen 4 p.6)
Athanasius: "Now certain Greeks ... make a double mistake: either in denying the Creator to be maker of all things, if evil had an independent subsistence and being of its own; or again, if they mean that He is maker of all things, they will of necessity admit Him to be maker of evil also. For evil, according to them, is included among existing things. ... they also wrongly think that evil has a substantive existence." (Against the Heathen 6 p.6-7)
Basil (329/330-379 A.D.) Prolegomena "On the other hand, of the evils of hell the cause is not God, but ourselves. The origin and root of sin is what is in our own control and our free will." (Prolegomena in the Nicene & Post- Nicene Church Fathers Second Series vol. 8 p.lviii)
Gregory Nazianzus (~330-391 A.D.) "Having honoured him [Adam] with the gift of Free Will (in order that God might belong to him as the result of his choice, no less than to Him who had implanted the seeds of it), ... (On the Theophany, or Birthday of Christ. Nicene & Post-Nicene Fathers Second Series vol.7 p.348
Gregory Nazianzus "...those detractors of all that is praiseworthy, those darkeners of light, uncultured in respect of wisdom, for whom Christ died in vain" (ibid p.349).
Gregory of Nyssa (331/335/336-395 A.D.) "Being the image and the likeness, as has been said, of the Power which rules all things, man [Adam] kept also in the matter of a Free-Will this likeness to Him who Will is over all.... and so he was a free agent, though circumvented with cunning, when he drew upon himself that disaster which now overwhelms humanity. ... for God did not make death. Man became, in fact himself the fabricator, to a certain extent, and the craftsman of evil. All who have the faculty of sight may enjoy equally the sunlight; and any one can if he likes put this enjoyment from him by shutting his eyes: in that case it is not that the sun retires and produces that darkness, but the man himself puts a barrier between his eye and the sunshine; ... Again, a man in building a house for himself may omit to make in it any way of entrance for the light; the will necessarily be in darkness, though he cuts himself off from the light voluntarily." (Nicene & Post-Nicene Fathers Second Series vol.5 On Virginity chapter 11 p.357) (See also On the Soul and the Resurrection p.457)
John of Damascus "for it would not be right to ascribe to God actions that are sometimes base and unjust; nor may we ascribe these to necessity, ...We are left then with this fact, that the man who acts and makes is himself the author of his own works, and is a creature endowed with free-will. Exposition of the Orthodox Faith chapter 25 Nicene & Post-Nicene Fathers 2nd Series vol.9 2nd p.40) We hold, therefore, that free-will comes on the scene at the same moment as reason," (ibid ch27 p.40)
John of Damascus "For chance is defined as the meeting and concurrence of two causes, originating in choice but bringing to pass something other than what is natural; for example, if a man finds a treasure while digging a ditch..." p.39
Cyril of Jerusalem (~315-335-386) "Cleanse thy vessel, that thou mayest receive grace more abundantly. For though remission of sins is given equally to all, the communion of the Holy Ghost is bestowed in proportion to each man’s faith" (First Catechetical Lecture I Nicene & Post-Nicene Fathers p.7)
Jerome (345-420 A.D.) (He wrote in a question an answer style between the orthodox Atticus and the Pelagian heretic Critobulus)
"Critobulus: "but what grieves me is this: that dignitaries of the Church, and those who usurp the title of master, destroy free will; and once that is destroyed, the way is open for the Manichaeans."
Atticus: Am I the destroyer of free will because, throughout the discussion, my single aim has been to maintain the omnipotence of God as well as free will?
Critobulus: How can you have free will, and yet say that man can do nothing without God’s assistance?
Atticus: If he is to be blamed who couples free will and God’s help, it follows that we ought to praise who does away with God’s help [sarcasm here]" Against the Pelagians Book III p.474
Hilary of Poitiers (300-367 A.D.) "Had this [will] been given, faith would carry with it no reward, for a necessity of will attached to us would also impose faith upon us." (On the Trinity viii 12 p.140-141.) See also On the Trinity vii 19 for the definition of free will and the free will of God.)
Theodoret (~393-423-458 A.D. accused of being a Nestorian but vindicated at Chalcedon) Dialogues III in the Nicene & Post Nicene Fathers 2nd Series vol.3 p.224 When the head of the race [Adam] was doomed, all the race was doomed with him, and so when the Saviour destroyed the curse, human nature won freedom"
Patrick of Ireland (~389-461 A.D. on losing salvation) "They are heading towards Hell; they cannot any longer be called Christians nor Romans [i.e. civilized] but outcasts. They must show signs of genuine and bitter repentance and try to make amends for their terrible crime." Patrick’s Letter to Corticus, a slave-trader.
John Chrysostom (345-martyred 407) on Rom 9:11-13 "What was the cause then why one [Jacob] was loved and the other [Esau] hated? Why was it that one served, the other was served? It was because one was wicked, and the other good. ... For when they were not as yet born, God said, ‘the elder shall serve the younger.’ With what intent then did God say this? Because He doth not wait, as man doth, to see from the issue of the acts the good and him who is not so, but even before these He knoweth which is the wicked and which not as such." Nicene & Post-Nicene Fathers First Series vol.11 p.464-465.)
John Chrysostom on Rom 9:20-21 "‘Shall the thing formed say to Him that formed it, Why hast Thou made me thus? Hath not the potter (Read Jer. 19:1-10) power, of the same lump to make one vessel unto honor, and another unto dishonor?’ Here it is not to do away with free-will that he says this, but to show, up to what point we ought to obey God. For in respect of calling God to account, we ought to be as little disposed to it as the clay is." (ibid p.467)
John Chrysostom "do not suppose that this is said by Paul as an account of the creation, nor as implying a necessity over the will, but to illustrate the sovereignty and difference of dispensations; for it we do not take it in this way, divers incongruities will follow, for if here he were speaking about the will, and those who are good and those not so, He will be Himself the Maker of these, and man will be free from all responsibility. And at this rate, Paul will also be shown to be at variance with himself, as he always bestows chief honor upon free choice. " (ibid p.468)
John Chrysostom on Eph 1:11 "‘...he [Paul] speaks also of inheritance by lot, yet so as not to divest them of free will.... It is as though he had said, lots were cast, and He hath chosen us’ but the whole is of deliberate choice. Men predestinated, that is to say, having chosen them to Himself, he hath separated. ... For marvellous is the foreknowledge of God, and acquainted with all things before their beginning.... According to the purpose,’ he says, ‘of Him who worketh all things after the counsel of His will.’ That is to say, He had no after working; having modeled all things from the very first, thus he leads forward all things ‘according to the counsel of His will. So that it was not merely because the Jews did not listen that He called the Gentiles, nor was it of mere necessity, nor was it on any inducement arising from them."
John Chrysostom on 2 Tim 2:4 "Imitate God! If He willeth that all men should be saved, there is reason why one should pray for all, if He hath willed that all should be saved, be thou willing also" Homilies on Timothy in Nicene & Post-Nicene Fathers 1st Series vol.13 p.430)
