St. Augustine wrote this work in the closing years of a life busied with three great controversies--Manichaeism, Donatism, Pelagianism, the last ending with the Contra Julianum and the Opus imperfectum contra Julianum.

Chapter 4
 
(. . .)
 
Of the number of the elect and predestined, even those who have led the very worst kind of life are led to repentance through the goodness of God, through whose patience they were not taken from this life in the commission of crimes; in order to show them and their co-heirs the depth of evil from which the grace of God delivers man. Not one of. them perishes, regardless of his age at death; never be it said that a man predestined to life would be permitted to end his life without the sacrament of the Mediator. Because of these men, our Lord says: 'This is the will of him who sent me, the Father, that I should lose nothing of what he has given me.'11 The other mortals, not of this number, who are of the same mass as these, but have been made vessels of wrath, are born for their advantage. God creates none of them rashly or fortuitously, and He also knows what good may be made from them, since He works good in the very gift of human nature in them, and through them He adorns the order of the present world. He leads none of them to the wholesome and spiritual repentance by which a man in Christ is reconciled to God, whether His patience in their regard be more generous or not unequal. Therefore, though all men, of the same mass of perdition and condemnation, unrepentant according to the hardness of their heart, treasure up wrath to themselves on the day of wrath when each will be repaid according to his works, God through His merciful goodness leads some of them to repentance, and according to his judgment does not lead others. Our Lord says He has the power to lead and draw men: 'No men can come to me unless the Father who sent me draw him.'12

Predestination is a protestant heresy.

Heresy.

Nobody is predestined to salvation. Salvation depends on free will to avoid being in mortal sin upon death. A person must freely choose to be in the state of grace upon their death. Christ gives us a choice to choose Him or reject Him, and our eternal reward or punishment depends on this free will. 

. . . heretical thread.

If you read the authorities cited in the  thread, and could actually say that, you need to do something other than discuss things outside your ken on forums like this, and so avoid making a fool of yourself. Or worse.

Maybe this trad hasn't quite realized that in rejecting predestination entirely the user accepts a Vatican II idea of salvation, since this is uniquely tied to "many" in the True Mass.

What merit is there for the predestined when being predestined guarantees a person salvation? That means there can't be any true free will for that person. To say "the predestined have free will" is illogical. Just admit that your belief is a contradiction. Your poor explanation is a contradiction. You're saying that God is the Author of confusion, when in reality, it is Satan who is the author of confusion. The fact is you don't even really know WTH you believe. All you can do is parrot something you read and post links, but you have no real understanding of it. How can you, when what you espouse makes no sense?

From this it follows that we must reckon among them also all children who die in baptismal grace, as well as those adults who, after a life stained with sin, are converted on their death-beds. The same is true of the numerous predestined who, though outside the pale of the true Church of Christ, yet depart from this life in the state of grace as catechumens, Protestants in good faith, schismatics, Jєωs, Mahommedans, and pagans. Those fortunate Catholics who at the close of a long life are still clothed in their baptismal innocence, or who after many relapses into mortal sin persevere till the end, are not indeed predestined more firmly, but are more signally favoured than the last-named categories of persons.
