How does your interpretation of CCC 366 explain the creation of two spiritual souls for one cell if that cell is destined to become two identical twins? Does the second soul get created when the ball of cells becomes recognizable as two embryos? Or are both souls created at the moment the first cell is fertilized?
Very good point. Here modern science, it has seemed to me since I learnt of this reality at my Catholic school in 1972, is a strong antidote to too simplistic an understanding of “soul and body” by the faithful (which is most of us, including myself).
(The traditional theological understanding of soul and body (and their relationship) is very deep and difficult. It certainly cannot be understood without understanding Aristotle’s philosphy of Hylomorphism from which it was derived by medieval theologians.)
If it is accepted that the very first clump of divided cells generated after fertilisation of the ovum (I won’t say “conception” because not everybody seems to accept this definition) can be “teased out” with a needle and each sub-clump or single cell will then become an identical twin embryo if left separated … then we seem to have a new theological problem.
We have a further problem if it is also accepted that these separated clumps (with their gelatinous coatings) can be easily stuck together again by human intervention and will still become that single embryo it was destined to be before “teasing out.” This is an even bigger difficulty for simplistic soul/body understanding.
Are we to say that we are one moment causing God to create human souls by means of a needle and then the next moment, when we push these identical cells together again,
they are being sent to limbo? And if the sub-clumps get pushed together again which soul “wins” … is it the original soul before the break-up, one of new souls, or yet another new soul?
(Scholastic theologians would not have seen this as a problem because they would say no eternal human soul is involved in early stages of pregnancy - we are only dealing with finite vegetative or animal “souls”).
And if the above apparantly luidicrous theological positions are not acceptable then when does a single, unique human soul actually get created?
Is it when the clump of cells can no longer be teased out successfully? Or is it when the initial repeated cell division into identical cells eventually stops and cell differentiation then begins within this “clump” instead? If so, then this is clearly at a time well after fertilisation of the ovum!
I do not know the answer. But what it does seem to mean, by extension, is that even in ordinary “scientific” debate use of concepts like body and soul may not be appropiate or helpful tools if we try to use them too forcefully or “scientifically”.
It seems, at the time of conception, we may not really know what these words/concepts mean or how they apply to the scientific facts as we understand them.
