I dont see him advocating imputation in those quotes though, so you dont have a case, in fact from the first source I saw quotes like this:“To declare His righteousness.” What is declaring of righteousness? Like the declaring of His riches, not only for Him to be rich Himself, but also to make others rich, or of life, not only that He is Himself living, but also that He makes the dead to live; and of His power, not only that He is Himself powerful, but also that He makes the feeble powerful. So also is the declaring of His righteousness not only that He is Himself righteous, but that He does also make them that are filled with the putrefying sores (κατασαπέντας ) of sin suddenly righteous.
This sounds like infusion of grace to me.
That quote says nothing of Mary so either you are desperate or cutting and pasting, or both.
There is nothing wrong with what he said. There are other quotes out there where St Chrysostom speaks of Peter as head/leader.
Some of what he says does sound like penal substitution but other things dont. I would have to look into it more.
He said that in a limited sense commenting on a passage where Paul said “Remember ye not, that when I was yet with you, I told you these things?” As for “sufficiency” he comments about the next chapter:
Ver. 15. “So then, brethren, stand fast, and hold the traditions which you were taught, whether by word, or by Epistle of ours.”
Hence it is manifest, that they did not deliver all things by Epistle, but many things also unwritten, and in like manner both the one and the other are worthy of credit. Therefore let us think the tradition of the Church also worthy of credit. It is a tradition, seek no farther. Here he shows that there were many who were shaken.
His comments on 2 Tim 3:16 I see nothing wrong with.
Out of all the quotes you provided for Augustine and Chrysostom I would say only a few raised any objection by me. Others didnt support your claim at all.
