If you're a Catholic feeling offended of me badmouthing your mother church, just say so. Don't dismiss this elephant in the room in you seriously wanna discuss the past 1500 years of church history instead of the first few hundred years of church history - aka, the "early church". Don't try to conflate these two and think I wouldn't notice the difference. The original Christianity is predoninantly Jewish, and their teachings were soly based on the OT, the only Scripture that they had, and regarding salvation specifically, the blueprint or paradigm of that is laid out in the Exodus from Egypt, that's argued in the book of Hebrews. From Acts to Revelation, Yeshua's miracles and teachings are rarely quoted or referenced, what's being frequently quoted or referenced is the OT theologies. If that's your angle, then we can have a meaningful discussion and explore further, otherwise, keep your complaint against the reformers to yourself.
I'm not Catholic, and I'm certainly not offended. However, you didn't answer my question. Are you willing to accept those things I mentioned that one has to accept in order to side with the Reformers. There's no need to discuss the Catholic church as it's irrelevant to the discussion. They didn't change the original teaching on this subject. They taught what had been taught prior to the Catholic church. But, if you'd like to discuss the early church we can do that.
Here is Justn Martyr,
Wherefore God delays causing the confusion and destruction of the whole world, by which the wicked angels and demons and men shall cease to exist, because of the seed of the Christians, who know that they are the cause of preservation in nature. Since, if it were not so, it would not have been possible for you to do these things, and to be impelled by evil spirits; but the fire of judgment would descend and utterly dissolve all things, even as formerly the flood left no one but him only with his family who is by us called Noah, and by you Deucalion, from whom again such vast numbers have sprung, some of them evil and others good. For so we say that there will be the conflagration, but not as the Stoics, according to their doctrine of all things being changed into one another, which seems most degrading.
But neither do we affirm that it is by fate that men do what they do, or suffer what they suffer,
but that each man by free choice acts rightly or sins; and that it is by the influence of the wicked demons that earnest men, such as Socrates and the like, suffer persecution and are in bonds, while Sardanapalus, Epicurus, and the like, seem to be blessed in abundance and glory.
The Stoics, not observing this, maintained that all things take place according to the necessity of fate.
But since God in the beginning made the race of angels and men with free-will, they will justly suffer in eternal fire the punishment of whatever sins they have committed. And this is the nature of all that is made, to be capable of vice and virtue. For neither would any of them be praiseworthy unless there were power to turn to both [virtue and vice]. And this also is shown by those men everywhere who have made laws and philosophized according to right reason, by their prescribing to do some things and refrain from others.

It's pretty clear Justin argued or free will. Calvin was a Stoic. as we see they held to the idea that all things were fated. Calvin simply changed his doctrine from fate to God. Same doctrine, different source.
Here is Origen refuting the doctrine of unconditional election. he calls those who hold this doctrine heretics.
8. Let us begin, then, with those words which were spoken to Pharaoh, who is said to have been hardened by God, in order that he might not let the people go; and, along with his case, the language of the apostle also will be considered, where he says, “Therefore He hath mercy on whom He will, and whom He will He hardeneth.”
For it is on these passages chiefly that the heretics rely, asserting that salvation is not in our own power, but that souls are of such a nature as must by all means be either lost or saved; and that in no way can a soul which is of an evil nature become good, or one which is of a virtuous nature be made bad. And hence they maintain that Pharaoh, too, being of a ruined nature, was on that account hardened by God, who hardens those that are of an earthly nature, but has compassion on those who are of a spiritual nature. Let us see, then, what is the meaning of their assertion; and let us, in the first place, request them to tell us whether they maintain that the soul of Pharaoh was of an earthly nature, such as they term lost. They will undoubtedly answer that it was of an earthly nature. If so, then to believe God, or to obey Him, when his nature opposed his so doing, was an impossibility. And if this were his condition by nature, what further need was there for his heart to be hardened, and this not once, but several times, unless indeed because it was possible for him to yield to persuasion? Nor could any one be said to be hardened by another, save him who of himself was not obdurate. And if he were not obdurate of himself, it follows that neither was he of an earthly nature, but such an one as might give way when overpowered2 by signs and wonders. But he was necessary for God’s purpose, in order that, for the saving of the multitude, He might manifest in him His power by his offering resistance to numerous miracles, and struggling against the will of God, and his heart being by this means said to be hardened. Such are our answers, in the first place, to these persons; and by these their assertion may be overturned, according to which they think that Pharaoh was destroyed in consequence of his evil nature. And with regard to the language of the Apostle Paul, we must answer them in a similar way. For who are they whom God hardens, according to your view? Those, namely, whom you term of a ruined nature, and who, I am to suppose, would have done something else had they not been hardened. If, indeed, they come to destruction in consequence of being hardened, they no longer perish naturally, but in virtue of what befalls them. Then, in the next place, upon whom does God show mercy? On those, namely, who are to be saved. And in what respect do those persons stand in need of a second compassion, who are to be saved once by their nature, and so come naturally to blessedness, except that it is shown even from their case, that, because it was possible for them to perish, they therefore obtain mercy, that so they may not perish, but come to salvation, and possess the kingdom of the good. And let this be our answer to those who devise and invent the fable of good or bad natures, i.e., of earthly or spiritual souls, in consequence of which, as they say, each one is either saved or lost.
9. And now we must return an answer also to those who would have the God of the law to be just only, and not also good; and let us ask such in what manner they consider the heart of Pharaoh to have been hardened by God—by what acts or by what prospective arrangements. For we must observe the conception of a God5 who in our opinion is both just and good, but according to them only just. And let them show us how a God whom they also acknowledge to be just, can with justice cause the heart of a man to be hardened, that, in consequence of that very hardening, he may sin and be ruined. And how shall the justice of God be defended, if He Himself is the cause of the destruction of those whom, owing to their unbelief (through their being hardened), He has afterwards condemned by the authority of a judge? For why does He blame him, saying, “But since thou wilt not let My people go, lo, I will smite all the first-born in Egypt, even thy first-born,” and whatever else was spoken through Moses by God to Pharaoh? For it behoves every one who maintains the truth of what is recorded in Scripture, and who desires to show that the God of the law and the prophets is just, to render a reason for all these things, and to show how there is in them nothing at all derogatory to the justice of God, since, although they deny His goodness, they admit that He is a just judge, and creator of the world. Different, however, is the method of our reply to those who assert that the creator of this world is a malignant being, i.e., a devil.
10. But since we acknowledge the God who spoke by Moses to be not only just, but also good, let us carefully inquire how it is in keeping with the character of a just and good Deity to have hardened the heart of Pharaoh. And let us see whether, following the example of the Apostle Paul, we are able to solve the difficulty by help of some parallel instances: if we can show, e.g., that by one and the same act God has pity upon one individual, but hardens another; not purposing or desiring that he who is hardened should be so, but because, in the manifestation of His goodness and patience, the heart of those who treat His kindness and forbearance with contempt and insolence is hardened by the punishment of their crimes being delayed; while those, on the other hand, who make His goodness and patience the occasion of their repentance and reformation, obtain compassion. To show more clearly, however, what we mean, let us take the illustration employed by the Apostle Paul in the Epistle to the Hebrews, where he says, “For the earth, which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, will receive blessing from God; but that which beareth thorns and briers is rejected, and is nigh unto cursing, whose end is to be burned.” Now from those words of Paul which we have quoted, it is clearly shown that by one and the same act on the part of God—that, viz., by which He sends rain upon the earth—one portion of the ground, when carefully cultivated, brings forth good fruits; while another, neglected and uncared for, produces thorns and thistles. And if one, speaking as it were in the person of the rain,2 were to say, “It is I, the rain, that have made the good fruits, and it is I that have caused the thorns and thistles to grow,” however hard the statement might appear, it would nevertheless be true; for unless the rain had fallen, neither fruits, nor thorns, nor thistles would have sprung up, whereas by the coming of the rain the earth gave birth to both. Now, although it is due to the beneficial action of the rain that the earth has produced herbs of both kinds, it is not to the rain that the diversity of the herbs is properly to be ascribed; but on those will justly rest the blame for the bad seed, who, although they might have turned up the ground by frequent ploughing, and have broken the clods by repeated harrowing, and have extirpated all useless and noxious weeds, and have cleared and prepared the fields for the coming showers by all the labour and toil which cultivation demands, have nevertheless neglected to do this, and who will accordingly reap briers and thorns, the most appropriate fruit of their sloth. And the consequence therefore is, that while the rain falls in kindness and impartiality4 equally upon the whole earth, yet, by one and the same operation of the rain, that soil which is cultivated yields with a blessing useful fruits to the diligent and careful cultivators, while that which has become hardened through the neglect of the husbandman brings forth only thorns and thistles. Let us therefore view those signs and miracles which were done by God, as the showers furnished by Him from above; and the purpose and desires of men, as the cultivated and uncultivated soil, which is of one and the same nature indeed, as is every soil compared with another, but not in one and the same state of cultivation. From which it follows that every one’s will, if untrained, and fierce, and barbarous, is either hardened by the miracles and wonders of God, growing more savage and thorny than ever, or it becomes more pliant, and yields itself up with the whole mind to obedience, if it be cleared from vice and subjected to training.
