Are you not reading what I am saying? I said specifically that what they wrote was not the same as the completed doctrine that Augustine or the Reformers laid out, but they were discussing the concept of total (yes, total) depravity/ability. Let me repost them here so you can see them again instead of just ignoring them.
I wonder how well read Dr. Michael Davidsson is on the Church Fathers. I couldn't find any information about him. It seems like he has been looking for quotes that support his position, without closer studying the whole letters.
From your Reformed lenses it may seem these quotes describe total depravity/total inability, but it's far from the truth. I made some comments under each quote.
Clement of Rome
“All therefore are glorified and magnified, not by themselves or their own works of righteous actions, which they have wrought out, but by his will,” (Clement, Ep. 1, ad. Corinth. p. 72.).
“‘not by ourselves, nor by our wisdom, or understanding, or piety, or the works which we have done in holiness of heart,’ but by faith by which God Almighty hath justified all from the beginning, to whom be glory for ever and ever. Amen,”
Clement is saying we can not be righteous through out own actions, rather we need to turn to God through faith. He is demonstrating it's not by our righteous actions, but by faith.
Ignatius of Antioch
“They that are carnal,” says he, “cannot do the things that are spiritual, nor they that are spiritual do the things that are carnal, as neither faith the things of unbelief, nor unbelief the things of faith,” (Ep. ad Ephesians p. 22.).
This is the Pauline teaching the flesh is against the Spirit, and the Spirit against the flesh. He is however not saying a carnal man can't turn to God to be a spiritual man.
Justin Martyr
“Mankind by Adam fell under death, and the deception of the serpent; that ‘we are born sinners;’ and that we are entirely flesh, and no good thing dwells in us; he asserts the weakness and disability of men either to understand or perform spiritual things, and denies that man, by the natural sharpness of his wit, can attain to the knowledge of divine things, or by any innate power in him save himself, and procure eternal life,” (Epist. ad Zenam, p. 506.).
“Having sometime before convinced us to of the impossibility of our nature to obtain life, hath now shown us the Savior, who is able to save that which otherwise were impossible to be saved,” (Epist. ad Diognet. p. 500.)
Justin is saying we can't obtain eternal life on our own, we need Christ. He believes humans, aided by God’s grace can respond to Him. He's a strong proponent of free will.
Irenaeus of Lyons
Man, “will be justly condemned, because being made rational, ‘he has lost true reason,’ and lives irrationally, is contrary to the justice of God, giving himself up to every earthly spirit, and serves all pleasure,” (Adv. Haeres. 1. 4, c. 16, p. 460.).
Irenaeus is describing the situation of mankind. All have fallen in sin, and they will be judged accordingly (unless they repent).
Origen of Alexandria
“In Adam,56 as saith the word, all die, and are condemned in the likeness of Adam’s transgression, which the divine word says not so much of some one, as of all mankind — for the curse of Adam is common to all,” (Contr. Cels. 1. 4, p. 191.).
“Because our free will is not sufficient to have a clean heart, but we are in need of God, who creates such an one; therefore it is said by him, who knew how to pray, Create in me a clean heart, O God!”(Contr. Cels. 1. 5, 1, 7, p. 354.).
Origen describes the whole mankind fallen in sin through Adam. We can't by our own free will have a clean heart. It's only by the help of God, therefore we are to pray to God to create a clean heart in us.
Lactantius
“We, who before as blind men, and as shut up in the prison of folly, sat in darkness, ignorant of God and truth, are enlightened by God, who hath adopted us in his covenant, and being delivered from evil bonds, and brought into the light of wisdom, he hath took into the inheritance of the heavenly kingdom,” (Divin. Institut. 1. 4, c. 20, p. 328.).
Lactantius says everything is given by God. It's He who enlightens us, adopts us, gives us the inheritance and it's not by ourselves. It's through God and it's to Him we need to turn.
Athanasius of Alexandria
“The devil wrought sin from the beginning in the rational and understanding nature of man; for which reason it is impossible for nature, being rational, and willing, and being under the condemnation of death, to restore itself to liberty,” Athanas. contr. Arian. orat. 2, vol. 1. p. 358. de Salutar. adv. Jes. Christ. vol. 1. p. 638.).
“Concerning being one with God, ““This phrase in us is the same as if it was said, that they may be made one by the power of the Father and of the Son; or without God it is impossible that this can be done,” (Athanas. de Incarnatione, orat. 4, p. 474.)
Again it's the same theme. We our helpless without God and need to turn to Him. It's impossible to restore oneself to freedom and it's only through the aid of God.
