I think there was always only one plan of God.
This seems sound, since God is omniscient. God wouldn’t strictly need a contingency, the way a human planner would.
He knew that man would have sinned.
That seems a strange way of saying it. He knew that man would sin. “Would have sinned,” implies that he didn’t. Now if in this thread we are discussing the hypothetical that he didn’t, I think a better way to say that is, “He would know that man would have sinned,” but this implies, of course, “except. . .” We can’t get around the fact that since man did sin, any world in which he had not sinned would be a different hypothetical world. It would have at least one difference — namely, that Adam did not sin. In such a world,
this world the way it turned out would qualify as a contingency on God’s part.
Actually, maybe that’s what it is. It seems to me that God would have preferred not to need to go through the Crucifixion for us. Yet, He knew, with infallible foreknowledge, that He would. What love!
And it is my observation that man would have sinned with or without the devil.
This, I’m not so sure about. Although, it does raise yet another hypothetical. If no angel had ever sinned, but man did, then perhaps man would be condemned without reprieve the way Satan and his angels were!
It is interesting to note the Eastern Church’s view on original sin is not as painful as it is portrayed in the West. The Eastern Church takes the view of her Church Father, St. John Chrysostom, that even though original sin entered into the world we are not guilty because of it or that this stain of original sin passes on to other generations.
I think the Catholic teaching is not that we are guilty but that we inherit concupiscence.
His views are quite remarkable and it is to my observations that he believes that Adam and Eve were not created at a very high height of sanctity but were created at the lowest level of sanctity and their sin was done at this level. It seems to this saint that man was created in order to become a saint. His fall while it is noted does not impress the saint to believe it was done at a great height.
If what you say about man being created to become a saint is true, then it seems that sanctification is a process he has to go through, so Adam and Eve were created, it would seem, in a “ground state.” The were created natural, and infused with supernatural grace. If increase in grace is sanctification, then it seems Adam and Eve would be created at a level 0 (lowest), and increase from there. Whether they sinned immediately after they were created or there was an interim time is a question. If there was an interim time, then it seems they would have increased in grace during that time, because the blessed in heaven continue to increase in grace and holiness, forever.
I guess it seems a little confusing to talk about a “very height” of sanctity — that seems like a possession of God alone. Human beings can be made more holy, more like God, but there is also always more holiness in store for us, since God is actually Infinite. So it seems Adam and Eve were created with a certain degree of holiness, and it seems they would have increased from there, but when they fell, it seems they lost what they initially had. In other words it seems that their state after the Fall was lower than their original state, if they were created in sanctifying grace and then lost that. So it seems sound to say that they fell from the greatest height of sanctity that they or any human had so far ever seen. Not that there are not greater heights — it is absurd to postulate an “absolute height” of sanctity unless we mean that possessed by God alone — but at that time, Adam and Eve, until they actually sinned at least in thought, were not on a decline in sanctity but an incline, the natural state of the blessed in God’s presence.
So it seems that, while Adam and Eve were certainly not created at any “very height” of sanctity, yet they were created without sin, so their sanctity, whatever the degree, was 100%. And they fell from that 100%. Perhaps, when they were created, they were kept in stasis with regard to their degree of sanctity, so that they did not actually increase beyond that in which they were created; perhaps, the choice of sin or virtue was first presented to them, before any increases of grace. Can it be that that was what Saint Chrysostom was saying?
