Augustine of Hippo, on 2Tim 2:19

“But the sure foundation of God standeth firm, having this seal: the Lord knoweth who are his; and let every one depart from iniquity who nameth the name of the Lord.”

“It is the elect who are meant in the letter to Timothy, where, after mention of the attempts of Hymenaeus and Philetus to undermine the faith, the text goes on, "But the sure foundation of God stands firm, bearing this seal: 'The Lord knows who are his.' " The faith of these latter, which works through charity, either does not ever fail, or, if it fail in some, the loss is repaired before death, the sin that intervened is blotted out and perseverance to the end is granted. On the other hand, those who are not to persevere to the end, those who are to fall from Christian faith and conduct, in such a way that the end of this life will find them thus fallen—these men are certainly not to be counted in the number of the elect, not even at the time during which they are living in goodness and piety.”
