There are certain questions that perennially puzzle the minds of men. Once these questions are answered, they often change the way reality itself is perceived. Perhaps one of the most foundational of these questions is how, if God is both omnipotent and omniscient, there can be any such thing as free will. Distilled down to its simplest form, the question relates to the possibility of God’s Providence and our freedom to choose. Thankfully, this question was cogently resolved over 1500 years ago by St. Boethius in his book The Consolation of Philosophy. Grasping what he taught will help us not only to address objections from non-believers but to strengthen our understanding and determination to cooperate with God’s Providence.
What is Providence?
As always, once we define our terms, the clouds blocking the rays of understanding are lifted. First there is Providence. God’s Providence is analogous to the virtue of prudence in that it represents the manner in which all things are directed towards their end. And like prudence, it has two aspects. The first is the eternal plan for creation. The second is the execution of this plan in time, which Boethius calls Fate. The first includes creating certain causes that are capable of carrying out His desired effects and the second is the employment of those secondary causes in time.
God’s plan is both immutable (unchangeable) and infallibly certain. This is because He is the universal cause to which all particular causes are subject. From this it follows that while it might be possible to avoid a particular cause, it is impossible to avoid the universal cause. As St Thomas puts it, one might freely choose to avoid a particular cause, but only
“through the intervention and hindrance of some other particular cause; as, for instance, wood may be prevented from burning, by the action of water. Since then, all particular causes are included under the universal cause, it could not be that any effect should take place outside the range of that universal cause. So far then as an effect escapes the order of a particular cause, it is said to be casual or fortuitous in respect to that cause; but if we regard the universal cause, outside whose range no effect can happen, it is said to be foreseen. Thus, for instance, the meeting of two servants, although to them it appears a chance circumstance, has been fully foreseen by their master, who has purposely sent to meet at the one place, in such a way that the one knows not about the other.” ST I, q.22, a.2 ad.2
There are two necessary consequences associated with this. The first is that there is nothing that happens that isn’t willed by God either directly or permissively. Second, there is no such thing as chance. Chance is merely our way of describing the experience of ignorance of the particular causes of thing since nothing can escape the universal cause.
God’s Foreknowledge
Notice that St. Thomas draws an important conclusion related to the existence of the universal cause. He says that everything that happens is also foreknown. This is where St. Boethius’ explanation about God’s foreknowledge is particularly useful. We use this term, foreknowledge, because it helps us to understand what God knows. But it does not really describe how God knows.

God is eternal. When we see this term, we think that means “He is outside of time”. It is this overly simplistic explanation that makes it difficult for us to grasp exactly how God knows. Saying that God is eternal means, according to Boethius, that He has “a possession of life, a possession simultaneously entire and perfect, which has no end” (Consolation of Philosophy, Book V). Eternity is changeless life possessed wholly at once so that God possesses His infinite life wholly at once. God lives in the eternal present and therefore everything happens at once.
God does not really foreknow anything. He knows all things because they are happening Now. It is like you knowing that you are reading the word word. Because He knows all things at once, He submits each particular cause to Himself as the universal cause in “real time”.
With this understanding in place, we see that there is no ideological conflict between Providence and free will. God’s knowledge of the choices of our will does not impose any necessity on them. His knowledge may be certain but that does not mean that the outcome itself was fixed. We still have the power to choose.
While there may be no ideological conflict between Providence and free will, there is, what for all of us, is an interior conflict. This is why Our Lord taught His disciples to pray “Thy will be done on earth as it is in heaven.” God’s will is immutable and thus we are not praying that what He wills happens, but that we will cooperate with it. The purpose of having free will is so that we can cling to God’s will. By understanding that God will is always accomplished, there is no reason for us to avoid it. The moment Providence reveals its plan to us, we should abandon ourselves to it and embrace what God has ordained. This is why we should leave the distinction between His active and permissive will to the theologians and focus only on the fact that both are willed.
It is always true that the foundational way for strengthening our resolve is to strengthen our understanding. This is exactly what St. Boethius was doing when he wrote The Consolation of Philosophy. He had been abandoned by everyone dear to him and left to rot in prison. In this midst of this great suffering, he turned to Lady Philosophy to help strengthen his resolve to abandon himself to God’s will. And once strengthened, he ultimately won the martyr’s crown.
