84. First the memory brings some passion-free thought into the intellect. By its lingering there, passion is aroused. When the passion is not eradicated, it persuades the intellect to assent to it. Once this assent is given, the actual sin is then committed. Therefore, when writing to converts from paganism, St Paul in his wisdom orders them first to eliminate the actual sin and then systematically to work back to the cause. The cause, as we have already said, is greed, which generates and promotes passion. I think that greed in this case means gluttony, because this is the mother and nurse of unchastity. For greed is a sin not only with regard to possessions hut also with regard to food, just as self-control likewise relates to both food and possessions.
This text provides one of the descriptions of the way a thought arouses a passion and the passion then translates into an act of actual sin. In some ways, I’m not totally unlike those ancient converts from paganism. I understand that you have to learn to see something as wrong, then stop doing it, and finally trace backwards the inward paths.
I don’t believe I had really considered greed as a form of gluttony, but it makes sense. They both manifest as the desire to acquire and consume more. Our modern American culture is a treacherous environment for us. Consumption and acquisition are considered to be the normal course of life. Perhaps in that way, we are all the new pagans?
