Did Augustine believe in the doctrine of Eternal Security?

I came across this article on Augustine: [Why Do We And St. Augustine Believe “Once Saved Always Saved”?](https://koinos.church/why-do-we-and-st-augustine-believe-once-saved-always-saved/) . The article explains: >Augustine saw in scripture that the fall of Adam resulted in all humans receiving a nature totally depraved so that no one is capable of obedience without God’s grace providing the ability. This is why he uttered his famous prayer, “Lord command what you will and grant what you command.” This view of man’s depravity and God’s grace caused him to reject the idea that believers must maintain their perseverance by their own righteousness. All God’s work of salvation in man is an act of His grace. None of it could be accomplished by the mere will of man, not the beginning steps of repentance and not the perseverance in faith to the end. All of salvation is due to God’s grace alone. This led him to make these affirmations on “once saved always saved,” > >>I assert, therefore, that the perseverance by which we peresevere in Christ even to the end is the gift of God. >> >>It is shown with sufficient clearness that the grace of God, which both begins a man’s faith and which enables it to persevere unto the end, is not given according to our merits, but is given according to His own most secret and at the same time most righteous, wise, and beneficent will; since those whom He predestinated, them He also called. >> >>When the gift of God is granted to them…none of the saints fails to keep his perseverance in holiness even to the end. (In De Perseverantiae). However, in [this debate](https://youtu.be/72TRODe8BdA?t=1411) , Trent Horn quoted a seemingly different passage from Augustine’s [*Treatise on Rebuke and Grace*](https://www.newadvent.org/fathers/1513.htm) : > If, however, **being already regenerate and justified**, he relapses of his own will into an evil life, assuredly he cannot say, I have not received, **because of his own free choice to evil he has lost the grace of God**, that he had received. I would like input from someone well-versed in Augustine’s writings: did Augustine’s views ultimately align with, or contradict, the doctrine of *Eternal Security*? Did Augustine actually believe in the doctrine of “once saved, always saved”?
