The discussion seems to have got a bit sidetracked.
The issue with omniscience is simply that no one can ever rebel against God’s knowledge, and therefore we have no free will.
This is an ill-conceived understanding of the issue.
Our free will does not stand in contention or opposition to God’s knowledge. It is concupiscence that makes us think that God is our enemy. In fact, to put it simply, God IS our free will. Our will IS free to the extent that we will what God does for us. His will for us is the embodiment of perfect free will for ourselves, anything else detracts from our own freedom and makes us less free and more compelled by the forces around us.
This was the view of people like Augustine, Boethius and Jesus himself.
To the Jews who had believed him, Jesus said, “If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free.”
They answered him, “We are Abraham’s descendants and have never been slaves of anyone. How can you say that we shall be set free?”
Jesus replied, “Very truly I tell you, **everyone who sins is a slave to sin. Now a slave has no permanent place in the family, but a son belongs to it forever. So if the Son sets you free, you will be free indeed. **I know that you are Abraham’s descendants. Yet you are looking for a way to kill me, because you have no room for my word. I am telling you what I have seen in the Father’s presence, and you are doing what you have heard from your father. ” (John 8:31-38)
According to the doctrine of omniscience, Judas had to betray Jesus, he had no choice. He could have wished with all his heart not to betray Jesus but he had to, because otherwise he would have proved God’s knowledge wrong.
This doesn’t follow. God knows what Judas would do BECAUSE Judas was going to do it, Judas did NOT do what he did BECAUSE God knew it. You have the causal connection backwards, which is fallacious thinking (retrospective determinism) on your part.
We are puppets dancing to whichever tune God’s knowledge plays, so we might as well do whatever we feel like, because if we can’t do other that what God knows we will do, why bother worrying about it.
That point entirely misconceives who and what God is. Furthermore, it is you arguing that “we can’t do other than what God knows” in a deterministic sense, so it is you arguing that we are puppets.
In any case, how could we do “whatever we feel like” if we are puppets?
My view is that we have made ourselves puppets and God seeks to set us free from the strings that we are entirely content to tie ourselves up with because freedom, in the true sense of taking ultimate responsibility for our actions, is a frightening proposition we would sooner find any reason to avoid than take on.
We are responsible because we are free and we are free precisely because God makes us autonomous agents and is continually using his knowledge to “cut the strings” that we keep retying. A sure sign of this is our compulsion to keep tracing the blame back to God being responsible for what we do, ad tedium.
Or to put it more technically, omniscience is duff.
Sure, and Einstein’s general theory of relativity appears to be “duff” to a slug that doesn’t understand it.
