Molinism is an interesting but dangerous concept. It is a shame that it is gaining a lot of ground among evangelicals, and is now a leading apologetic in questions about the problem of evil.
Molinism, or Middle Knowledge (scientia media), should not be confused with Modalism or Monism. Molinism is a view of the relationship between God’s grace and human free will. It originated with the Jesuit theologian, Luis de Molina (1535-1600), a Spaniard, who debated the Dominican Order over the topic.
It assumes God must “wait” to know things are true. But even children can tell you that God is eternal. He therefore has an eternal perspective, knowing things before they occur in time. He does not have to “wait” to know anything.
While proponents of Molinism attempt to provide an easy to understand account of human freedom and divine sovereignty, they begin with the premise that scientia media is indeed a biblical fact. Actually, they have gone so far as to call it a “doctrine.” And whose doctrine is it?
First of all, there is no such thing as counterfactuals. Counterfactual history is a myth propounded by philosophers who dip into in theology as a side hobby. There is no “alternative history” as purported by the Molinists. The only history that exists is His Story.
There are no Plan B’s in God’s Plan, only Plan A. God does not need a Plan B. God does not possess a “middle knowledge.” Whatever knowledge God has, He has it because what occurs and comes to pass is in fact His own divine decree determined from eternity past. There are no “worlds” beyond God’s plan.
The Molinist view implies that the world has events happening whereby His creatures determine what will transpire, and then God decrees what will come to pass after the fact. In other words, God has an endless supply of backup plans. In their view, God can tidy up after the decisions of men have been made and see to it that His own will is fulfilled.
Contrary to what Molinists claim, Acts 2:23 does not need Middle Knowledge philosophers to make it understandable to the theologians. The theologians understand it just fine without the Molinists’ help.
