God determining, or God determined, there is no other alternative. This is the famous dilemma Fr. Reginald Garrigou-Lagrange sets before his reader throughout the entirety of his masterful work, "Predestination." Either God is He who is Pure Act, the First Cause of all being and action (since action follows being), or the creature determines itself, which means God's foreknowledge of the creature's act is determined by the creature, implying a passive potency in the Divine nature.
Before moving into the primarily theses and lines of argument in Fr. Garrigou-Lagrange's book, I will begin by noting only a few slight drawbacks that are outweighed a hundredfold by the brilliance of this work.
First, if one does not have some basic familiarity with the thought of the Angelic Doctor on motion, God's foreknowledge, and human freedom, this book will be a difficult read. It will not be impossible to read this work, and the beginner may consult those questions and articles of Saint Thomas' works cited by Fr. Garrigou-Lagrange as one reads the book, but it will be a difficult read.
Second, although the subtitle is "The Meaning of Predestination in Scripture and the Church," and for good reason, as Fr. Garrigou-Lagrange depends quite heavily on the Scriptural foundations of predestination and the authority of the Church Councils including the Council of Trent and the Second Council of Orange, the author is not seeking to defend a "merely" Catholic exposition on predestination. As will be evident from the work, there is not one universal Catholic position on predestination, but various articulations on the doctrine from various schools including the Thomists, the Molinists, the Congruists, the Scotists, and the Augustinians. Fr. Garrigou-Lagrange extols and defends the view of the Thomist tradition against all these schools and the heresies of Pelagianism, semi-Pelagianism, Jansenism, and Calvinism. However, a deep study or nuances position on these other schools and heretical positions is not conducted by Fr. Garrigou-Lagrange (as this is not the chief aim), so one may consult other works on these other positions with profit.
Third, Fr. Garrigou-Lagrange is a repetitive writer. Many lines of argument will be repeated quite frequently, along with the same prooftexts from Scripture, the Magisterium, Saint Thomas, and other interlocutors. However, Fr. Garrigou-Lagrange is aware of this repetitive style, noting the intention behind it on p. 353, fn. 2.
Now we can address (only a few) of the great insights one will take away from reading the work of this Dominican master.
First, this work will provide a comprehensive overview of the Thomistic tradition's articulation of the mysteries of predestination and reprobation, while at the same time consistently showing how the Thomistic tradition's articulation of predestination rests firmly in the principles and thought of the school's master, Saint Thomas Aquinas, and more importantly, in God's revelation in Sacred Scripture and the Church.
Second, Fr. Garrigou-Lagrange succinctly captures the tension of two revealed doctrines. God desires that all shall be saved and one thing would not be greater than another if God did not love it more. This second principle, known as the principle of predilection, follows from the metaphysical principle that God's love is the cause of all goodness. Thus, if one thing is said to be more good, it is because God loves it more. This is true both in the natural and supernatural orders. Thus, if two men are put in similar circumstances, and one man sins while the other perseveres, the man who perseveres does so because he has received a greater Divine help, without which he would be unable to persevere, because persevering in good is itself a good, and all goodness comes from God as from a First Cause. This tension is reconciled according to the principles of Saint Thomas, without the mystery of predestination itself ever being placed at risk of being reduced to a rationalistic explanation (see pps. 336-337 on the proper mystery in predestination and its relationship to infused contemplation).
Third, Fr. Garrigou-Lagrange nods at the spiritual fruits of the Thomistic articulation of predestination throughout the text. Far from being a source of despair, the Thomistic articulation of predestination provides the surest foundation for the theological virtue of hope, since the formal object of hope is God and the divine assistance. As such, the Thomistic understanding of predestination excludes all pride, for what good does one have that does not come from God. "What do you have that you did not receive? And if you received it, why do you boast as if it were not a gift?" (1 Cor. 4:7).
Fourth, regarding Molinism, Fr. Garrigou-Lagrange will prioritize three arguments: (1) the affirmation of the universality of the principle of predilection, (2) the scientia media results in both a passive potency in the Divine knowledge and leads to a determinism of circumstances/fatalism, and (3) posits a definition of human freedom that contradicts both experience what could be known a priori. On this last point, the reason Fr. Garrigou-Lagrange assigns to the Molinist's incorrect definition of liberty is because they do not follow the proper order of procedure in defining a faculty according to its formal object which specifies the faculty and its acts. The Molinist never specifies the object of the free will. Fr. Garrigou-Lagrange notes well, however, that the primary problem with Molinism, in contradistinction with all of the other Catholic theories of predestination, is that it denies the intrinsic efficaciousness of grace, and argues that grace is only extrinsically efficacious, and becomes efficacious through a determination to the good by the created will. The rejection of physical premotion is a secondary issue that is not of principle concern to the Thomist, although the Thomist will defend it. As the author writes,
"It is of importance to note here that the doctrine of intrinsically efficacious grace, which is admitted almost all theologians who reject the scientia media, means far more for the Thomists than their explanation of predetermining physical premotion. Likewise, provided it is within the power of our will to move our hand as it pleases, it is of little consequence for us to know by means of what nerve centers it does so. Among the Thomists, Billuart pointed this out. He said in substance that the theologians explain in various ways the efficacy of grace: some by means of delectation [Augustinians] and moral influence [Congruists], others by physical predetermination [Thomists], though they do not apply this to natural acts, or to the material element in sin. But strictly speaking, these are philosophical questions, whereas grace efficacious of itself in virtue of God's omnipotent will, independently of the creature's consent and the scientia media, this we defend as a theological conclusion that is connected with the principles of the faith and proximate to the faith (proximately definable). If we exclude the Molinists, this opinion is held by almost all the schools" (p. 311).
This leads us to our last point regarding physical premotion. Fr. Garrigou-Lagrange defends this doctrine both in its substance, and also as being according to the mind of Saint Thomas Aquinas. Though Saint Thomas does not use the language of physical premotion, this terminology is taken up by Domingo Bañez in response to other theories of grace. As another author cited by Fr. Garrigou-Lagrange in the third appendix (well-worth reading) of the book states, "It is not a question of a name but of a thing. If one does not care for the name, give it up." (p. 367). Accordingly, Fr. Garrigou-Lagrange defends physical premotion from false understandings of the notion, and argues that physical premotion not only best explains the intrinsic efficaciousness of grace, but does so according to the principles of Saint Thomas on motion and causality, and in a way superior to that of the Augustinians and Congruists who argue that God infallibly moves the will by way of moral causality or a victorious delectation.
Much more could be said about this superb work on the mystery of predestination. For those who are seeking to ascend the hights of this mystery on the foundation of the most solid principles in speculative theology, as far as can be done on this side of eternity, Fr. Reginald Garrigou-Lagrange is a most excellent companion and guide in this ascent, and his "Predestination" is well worth its weight in gold.
