Being wounded by Original Sin did not radically change Adam and Eveās basic human nature of body and soul.
All good stuff GM but a few minor observations.
**"Did not radically **change
Adam and Eveās basic human nature of body and soul"
I know what you are trying to say but you may have categories of being a little mixed up (using the word āchangedā in reference to āhuman natureā prob isnāt helpful) and end up underplaying the true gravity of the Wound which the Church indeed asserts.
As the CCC states: āhuman nature has not been totally corruptedā which means it came pretty close. I think that if we stick with the word 'corrupted" rather than āchangedā things will fall into the right places.
No wound (great or small) can really change ābasic human natureā as you call it. Such natures are by definition fixed and static. A human-being will always be composed of body and soul. The only āchangeā that definition could possibly undergo is that God rescinds His Divine Idea (blueprint if you wish)ā¦then āpoofā all concrete humans disappear as if they never existed.
But back to the CCC, what does serious ācorruptionā mean? I suggest it is not about the ontological status of āhuman natureā being attacked (which your expression above formulation suggests), rather the exercise/use of the powers inherent and given to us in that fixed human nature.
Just as a serious physical wound means we lose the
use of certain bodily powers
(e.g. the use of a leg) so too by OS have we lost considerable facility **in the use **of inherent spiritual powers we still possess - which lie completely latent or very weak. This is often explained as the sofully ul losing its ānormalā dominion over the body.
In short, the Wound has nothing to do with attacking or changing ābasic human natureā at all. This is not really possible. Which is what I believe was the point you were making.
It has everything to do with our very seriously weakened mastery or use of the āpowersā always inherent in human nature wounded or not. As the CCC puts it: āhuman nature is wounded in the natural
powers proper to itā¦ā (ie in the use of the powers).
Of all the creatures mentioned in the beginning of Genesis, Adam is totally unique.
This may not be as black and white as you state. Do you have an authoritative Magisterial source for this affirmation?
I believe, at least in terms of the book of Genesis itself, Eve can be viewed as just as unique as Adam wrt origination of the human species if that is what you mean.
There are in fact two Creation accounts in Genesis. In the first account Adam and Eve are both directly created by God. Only in the second account is Eve derived from Adam.
To opine that the second Account is but an amplification of the first does not appear very tenable as an explanation to resolve this textual contradiction. This is because on some significant points the two accounts are contradictory. This is the main reason why scholars believe the author of Genesis combined at least two very different source materials from different Hebrew tribal sources.
So if Genesis itself has contradictory views on the āuniquenessā of Adam as originator of the human race I find it difficult to believe we can support a theological doctrine upon it.
But then again maybe the Church has settled the matter despite Genesis

Hence if you have come across a clear Magisterial source on this point I would be quite interested to check it out.
I have noticed over the years that you use this phrase a lot yet it is really a redundancy isnāt it?
The soul is by its very nature immaterial - which is the primary meaning of āspiritualā in Catholic philosophy. There is no such thing as a āmaterial soulā (though at a stretch one might be signifying a body).
Everybody knows that souls are immaterial - so I am wondering what special meaning you may be intentionally averting readers to by the construction?
Or is it that you are simply part quoting the CCC which uses this construction only when explicitly contrasting the difference between soul and body, as in:
āO wondrous vision, which makes us contemplate the human race in the unity of its origin in God. . . in the unity of its nature, composed equally in all men of a material body and a spiritual soulā?
