John Calvin wrote many pages about his belief in predestination, and it would be difficult to properly summarize them all here. Instead, here is an excerpt from The Institutes of Christian Religion. This text is from the chapter on predestination. You can read more of the chapter here if you wish. This is the excerpt:
Predestination, by which God adopts some to the hope of life, and adjudges others to eternal death, no one, desirous of the credit of piety, dares absolutely to deny. But it is involved in many cavils, especially by those who make foreknowledge the cause of it. We maintain, that both belong to God; but it is preposterous to represent one as dependent on the other. When we attribute foreknowledge to God, we mean that all things have ever been, and perpetually remain, before His eyes, so that to His knowledge nothing in future or past, but all things are present; and present in such a manner, that He does not merely conceive of them from ideas formed in His mind, as things remembered by us appear present to our minds, but really beholds and sees them as if actually placed before Him. And this foreknowledge extends to the whole world, and to all the creatures. Predestination we call the eternal decree of God, by which He has determined in Himself what would have to become of every individual of mankind. For they are not all created with a similar destiny; but eternal life is fore-ordained for some, and eternal damnation for others. Every man, therefore, being created for one or the other of these ends, we say, he is predestinated either to life or to death. This God has not only testified in particular persons, but has given a specimen of it in the whole posterity of Abraham, which should evidently show the future condition of every nation to depend upon His decision. “When the Most High divided the nations, when he separated the sons of Adam, the Lord’s portion was His people; Jacob was the lot of His inheritance.”
If you presume the existence of God and also his omniscience, then you may assume that God knows ahead of time who will be saved and who will be damned. Thus God being totally sovereign as well means he DECREES the eternal fates of individuals. The elect go to heaven, the rejected go to hell.
But where is the justice in that? If people have no choice in the matter, how can subjecting people to a final judgement make sense? Would it be reasonable for a suspect brought to trial for a crime to argue that he had no choice when he committed his acts of murder or theft? And if he was forced to do those crimes, wouldn’t that be a defense for NOT imprisoning him?
This dilemma would be solved by rejecting the notion of God’s omniscience….or by rejecting theism completely. John Calvin was a delusional idiot.
Not to mention he had put to death Michael Servetus for rejecting the Trinity and therefore being one of the Unitarians. Thus showing what a hypocrite Calvin was after he rebelled against the Roman Catholic Church! Freedom for me, not for thee.
