So, was Augustine espousing the correct view of the Catholic church when he said that “We know that God’s grace is not given to all men . To those to whom it is given it is given neither according to the merits of works, nor according to the merits of the will, but by free grace. To those to whom it is not given we know that it is because of God’s righteous judgment that it is not given.” (Augustine, Treatise On Rebuke and Grace), or is he a heretic of the Catholic church?
If he is to be believed, then what he has said above was “moved by the authority of the Catholic Church.” It appears that the Church’s teaching has changed, or Augustine was lying when he said he was “moved by the authority of the Catholic Church.”
"But at that time even mercy itself shall be allotted in righteous judgment in accordance with the merits of good works. For when it is said, Judgment without mercy to him that has showed no mercy, it is plainly shown that in those in whom are found the good works of mercy, judgment shall be executed with mercy; and thus even that mercy itself shall be returned to the merits of good works." (Ch. 41)
