Perhaps I misunderstand what the definition of a human soul is when it is called a “substance-less form,” and I know not all Catholic theological traditions follow the Thomistic understanding.
But it seems to be the dominant understanding of what a soul is.
So if after death, the form of the body remains, and if the soul is not a substance, then how can it act on its own, especially be conscious and pray for us on Earth, before it is reunited with its resurrected body?
Gravity is immaterial, but it is there. And yet, it has no substance. How then can it work? An act? A dimensionless phenomenon that took an apple to fall on a certain English man’s head, to explore what is this event.
Radio signals, are immaterial. For even a signal coming from a satellite is immaterial. But yet, we can measure radio signals by band.
Sound and gravity are immaterial. Meaning, substance-less as what is meant by it in physics/science.
Then, what governs a flower to be a flower? Or then, what governs the elements to work in a particular way, to be fashioned and formed? For that h2o is water. And no other atomic configuration as that, could make up water. So something governs, makes, shapes, and forms a thing to be. And the necessary governance of the that order governs it so that it can only be sustained and maintained in that way.
Consider love. That is immaterial. But a trait of human character no doubt. And then hatred is also immaterial. And yet, they act through the body.
If all those immaterial things hold to be true, how can Aristotle or any of the Greek Classicists argue against the ability of saints to pray?
For saints do not come from the natural order, but rendered by God on the human soul (the person.) And, the same governance and order served out by that God, also rendered to come into the existence of flesh. Because all things are possible with God. Even His ability that His Word, the closest person to the bosom of the Father. Could no doubt, no less, be able to take on human form: a body. And that was Him, incarnate.
Those are possibilities by God, by a Creator, Who so governs the universe, and made things to be, and stand as they stand. And thus, all/both the material/immaterial presence: the visible, and invisible. As we say in the Creed.
Aristotle, could easily observe that then, as we do with the marvel of science today. Just as Sir Isaac discovered this event called gravity.
