As you see here in replies like Ghosty’s, popular contemporary opinions lean toward the Molinistic side. But it would be incorrect to say that there are currently no defenders of Thomism. Garrigou-Lagrange, one of the most celebrated theologians of the 20th century, was an ardent Thomist, and many Dominican and Thomistic schools support the doctrine.
As Ludwig Ott helpfully points out in Fundamentals of Catholic Dogma, the dispute revolves around two poles: divine universal causation and God’s universal salvific will. The traditional Catholic theologian is strongly committed to both of these doctrines. Divine universal causation says that God is the cause of every single thing that is real–all things that exist are created by God. God’s universal salvific will is the idea that God desires that all men be saved (1 Timothy 2:4, 2 Peter 3:9). Molinists stress God’s universal salvific will, and Thomists (or Banezians) stress divine universal causation.
Instead of trying to explain why these doctrines are at the heart of the issue, it may be easier to see how they play into the
prima facie objections. Here are the two paradigmatic objections simplified:
Molinist: God must first look to see how we will respond to His grace before he decides how he will create the world and distribute grace.
Thomist: But if that is true, then God does not cause everything, and he must wait on human decisions before deciding what to cause. The human decision is in some sense uncaused since it is (logically) prior to God’s causal activity and an action of the Creator is somehow dependent on the actions of creatures!
Thomist: God causes the elect to freely cooperate with his grace. Since God is the creator of all things, it is not impossible for him to cause free cooperation.
Molinist: I deny that God can cause truly free cooperation. Therefore your position entails a sort of fatalism with respect to cooperation with grace. If God only causes some people to freely cooperate, then how can we say that he desires all to be saved?
These positions are very nuanced, and an official debate went on for many years in the Church regarding them (see 4 below). To my mind, Molinism is analogous to Arminianism, and Thomism is analogous to Calvinism. That is, they are motivated by some of the same factors, but Arminianism and Calvinism are very much further apart than Molinism and Thomism. The Catholic positions are also inevitably much more theologically rigorous. Because of this, an understanding of the Protestant positions may be a good preliminary measure to understanding the Catholic positions.
