If dogmas are infallible, how is the Church’s teaching on original sin reconciled with the symbolic nature of Adam and Eve when it (Adam and Eve) was most likely not symbolic at the time of the declaration of the corresponding dogma?
It only becomes a problem if we think too much of original sin as a genetic defect passed on from person to person, but I don’t think that’s the best or only way to think about it, and neither do I think the Church requires us to think of it strictly in that manner.
Original sin can be thought of the sin of the race itself, which is why it’s said somewhere that in Adam, the race was tested and fell, and in Jesus, the race was redeemed. Original sin is not Adam’s personal guilt passed on to us, but rather Adam, the race (of which he was representative) fell and sin came into the world.
Now if it should be found through science that there was no genetic Adam, then we should not fear it. Scientific truth is still truth, and since the Church believes the Truth is not a What, but a Who, then Truth is one, and scientific truth will never contradict religious truth. Perhaps it may be acceptable to think that in light of some hypothetical future scientific confirmation of polygenism, then perhaps “Adam” is the human race in its primordial state and as a race, it sinned, thereby introducing original sin into the world. I won’t know for sure, but I don’t see at this point how that would be incompatible with the Christian faith.
I know for a fact that original sin exists; we see this in the state of man throughout history, and even today. We see it in the concupiscence we ourselves experience, and the actual sins we commit. Man is a fallen race. That much is obvious. I also know, from critical and historical studies, that Jesus did come into world, make claims of Godhood, died, and rose. So there must be truth to the teaching of original sin and in the redemption from it.
That said, with scientific studies on evolution still going on, there’s not sufficient evidence to prove beyond a shadow of a doubt that polygenism is absolutely true, so I currently still hold on to monogenism. All I’m saying is that I’m not afraid of what science will discover, because we do not believe in a conflict between scientific truth and the truths of salvation.
