The Roman Catholic Church does not teach inherited guilt either. The doctrine is confusing though because of their stance on infant baptism and it is often misunderstood in everyday thought. I think the sacraments are very. nuanced in Catholicism. Original sin is a loss of the supernatural grace God originally bestowed on the first couple. We cannot understand original sin without understanding human nature, what we were made for and all the details of that first sin. Feser writes:
But according to Christian theology, God offered to our first parents more than what was “owed” to us given our nature. He offered us a supernatural gift. Here it is crucial to understand what “supernatural” means in this context. It has nothing to do with ghosts, goblins, and the like. What is meant is rather that God offered us a good that went above or beyond what our nature required us to have. In particular, he offered Adam and Eve the beatific vision – a direct, “face to face” knowledge of the divine essence which far transcends the very limited knowledge of God we can have through natural reason, and which would entail unsurpassable bliss of a kind we could never attain given our natural powers. He also offered special helps that would deliver us from the limitations of our natures – that would free us from the ignorance and error our intellectual limitations open the door to, the moral errors our weak wills lead us into, the sicknesses and injuries our bodily limitations make possible, and so forth.
By definition, none of this was “owed” to us, precisely because it is supernatural. Hence while God cannot fail to will for us what is good for us given our nature, He would have done us no wrong in refraining from offering these supernatural gifts to us, precisely because they go beyond what our nature requires for our fulfillment. Still, He offered them to us anyway. But this offer was conditional.
The world is as it was according to science before Adam and Eve’s sin. Feser continues:
The condition was the obedience of our first parents. Yet they did not obey. And of course, that is the point of the account of their eating of the fruit of the tree of knowledge. It wasn’t fruit per se that was important, but rather the will to rebel against the Creator. (Recall Augustine’s youthful theft of the pears, where what was attractive about the theft was the fact that it was forbidden, not the fact that he got some pears out of it.) The penalty was the loss of the supernatural gifts they had been given and that their descendants would have been given, and a fall back into their merely natural state, with all its limitations. In particular, it was a loss of all the helps that would effectively have removed those limitations – and worst of all, loss of the beatific vision.
In short, the penalty of original sin was a privation, not a positive harm inflicted on human beings but rather the absence of a benefit they never had a right to or strict need for in the first place but would have received anyway had they not disobeyed. . . . And it wasn’t the prospect of pitchforks and hellfire that Adam’s descendents had to look forward to because of what Adam did, but rather the privation of this supernatural gift.
And finally, he offers an analogy:
You might compare the situation to that of a landowner who has sold an unimproved parcel of land to a certain family – which, just to be cute, we’ll call the Adams family. In allowing the Adamses to take possession of the parcel, he’s given them everything he owed them. But suppose he offers to throw in, for free, something extra – to plant on the land a vineyard using the finest quality vines, whose fruit will make possible the best wine. This is something that all the descendents of the original Adamses who bought the land will profit from. But the landowner makes the offer only conditionally. He wants to see how Mr. and Mrs. Adams are going to handle things before turning the vineyard over to the Adams family as a whole, including the many descendents who are not likely to do any better with the vines than their ancestors are. So if Mr. and Mrs. Adams do well with the first vines planted, they and their descendents will get to keep them and reap the benefits. If not, the landowner will tear them out and leave the Adamses and their descendents with only the original unimproved parcel, which is all they were owed in the first place.
Now suppose that Mr. and Mrs. Adams botch things up, and the landowner removes the vineyard. The fault is entirely theirs, but all their descendents necessarily suffer the penalty just as much as they do, just by virtue of being Adamses. Yet it is not a positive harm that is inflicted on them, but rather the loss of a benefit they were not entitled to but nevertheless would have received if not for the actions of their ancestors.
What do we inherit? Feser writes:
Similarly, we inherit the penalty of original sin, not in the sense that we’ve got some “original sin gene” alongside genes for eye color and tooth enamel, but rather in the sense that the offer of the supernatural gifts was made to the human race as a whole through their first parent acting as their representative. Inheriting this penalty from Adam is more like inheriting your father’s name or bank account than it is like inheriting his looks or his temperament. And there is no more injustice in this inheritance than there is in the landowner’s not planting a vineyard for Mr. and Mrs. Adams’ descendents.
Obviously the account depends crucially on the distinction between the natural and supernatural orders – a distinction that was blurred in Protestantism and has also been blurred by some modern Catholic theologians (a tendency criticized by Pope Pius XII at paragraph 26 of Humani Generis ). Part of the danger of blurring it is that doing so threatens to make a hash of the doctrine of original sin. If Adam and Eve lost for us something we are in some sense owed by nature, or if the penalty of original sin did involve some positive damage to that nature rather than merely the privation of a supernatural gift, then it does come to seem unjust that we have inherited that penalty, and the door is opened at least a crack to the caricatures of the doctrine’s critics.
This is a scholastic position on original sin and I think it provides a valid answer to what @Marshall wrote. These quotes all come from is a series of blog posts I came across where Feser is addressing biology and original sin and defending genealogical Adam and Eve long before Swamidass’s book was written. He seems to indicate this view goes back quite far as well.
