53. As the world of the body consists of things, so the world of the intellect consists of conceptual images. And as the body fornicates with the body of a woman, so the intellect, forming a picture of its own body, fornicates with the conceptual image of a woman. For in the mind it sees the form of its own body having intercourse with the form of a woman. Similarly, through the form of its own body, it mentally attacks the form of someone who has given it offense. The same is true with respect to other sins. For what the body acts out in the world of things, the intellect also acts out in the world of conceptual images.
This text further drives home the point of the last text. Our nous, intellect, or heart cannot be separated from our body. As one goes, so the other tends to follow. St. Maximos is actually refuting an aspect of pagan philosophy that held that spiritual is pure or good while the material is evil. Too many people today have brought that idea or similar ideas that our bodies and spirits are somehow discontinuous and have independent existence into modern Christianity. We are whole beings. We cannot do things with our bodies without affecting our spiritual selves and that toward which we attune ourselves spiritually manifests in our bodies. Over time, we become that which we truly worship. In that truth we see the reality of both salvation and damnation.
