Dr. Craig Blomberg of Denver Seminary has written on why he would consider himself a Calminian (a supposedly bran’ new hybrid between Calvinism and Arminianism). There have been several excellent responses to this post already: Josh Walker, Andrew Compton, and Turretin Fan. Josh’s point is that counting heads does not truth make (or else Athanasius is in big trouble!). Andrew’s point is that Blomberg’s statement lacks historical and theological nuance because he hasn’t taken the trouble to read the best Reformed authors on these points. Turretin Fan’s point is that Blomberg is not actually between Calvinism and Arminianism. Rather, he is more between Calvinism and Open Theism. All of these points need to be made.
First of all, let’s define middle knowledge. Turretin’s definition is as good a place to go as any:
The authors (Fonseca, Lessius, and Molina, in context, LK) explain this middle knowledge to mean the foreknowledge of God about future conditional events whose truth depends not upon the free decree of God (being anterior to this), but upon the liberty of the creature (which God certainly foresees). See IET, I, p. 213.
This is the good ol’ God-looks-down-the-corridor-of-time-and-sees-faith-and-therefore-elects kind of doctrine. Turretin Fan is right. This is pure Arminianism, not Calvinism at all. Turretin notes that “the design of the Jesuits was to defend the semi-Pelagian heresy of foreseen faith and good works in election, and to support the figment of free will in order the more easily to free themselves from the arguments of the Dominicans who rejected such a foresight” (IET, I, p. 213). Turretin has a number of excellent objections to the idea of middle knowledge (pp. 214-216): 1. Natural and free knowledge (these are the two knowledges in between which middle knowledge is supposed to exist, the former being simple intelligence, the latter being definite knowledge of things, LK) embrace all knowable things. 2. Things not true cannot be foreknown as true. 3. No uncertain knowledge should be ascribed to God. 4. Middle knowledge takes away the dominion of God over free acts. This makes God dependent on the creature.
It would have been wise of Dr. Blomberg to consult some of these readily available sources before venturing into territory which is not his specialty. He would thence have been able to avoid both historical and systematic theological error.
