I just realized something after viewing an explanation of “Middle Knowledge” (Molinism).
In the Avenger film “End Game” we have a great example of Middle Knowledge. Dr. Strange is looking at all the possibilities of how the war against Thanus will turn out based on the coming initial battle with Thanus. Then Dr. Strange chooses the 1 reality out of the possible 14,000,65 worlds where an outcome is arrived at that defeats Thanus and chooses that one by means of his owning the “time stone.”
But the failure here by Christians, in applying this Dr. Strange like idea of middle knowledge to God is that when one does this one has a God who remains responsible for creating a World where sin comes into existence and therefore God is responsible for that world existing and so the sin that exists in that world. God sovereignly chose to actually create that possible world as among many different options and so God is responsible for the free will that man uses is that universe because God created that universe.
This is key, because the Arminian and the Molinist will insist that somehow their denial of Calvinistic predestination and sovereignty and their embraced of middle knowledge somehow gets God off the hook of being responsible for man’s sin. However, if God created a world where He knew sin would occur — even if it was the best of all possible worlds he could create — then God is responsible and the Arminian’s / Molinist solution to the problem of sin isn’t a solution. Not only isn’t it a solution to the problem of evil, it adds the problem that God is now a wimp deity who does not want sin but, having chosen the best possible world, sin is now beyond his control.
