Yes, it implies ensoulment.
There is no human life without the presence of a human soul - the soul is the source of our physical life.
I agree that there is, indeed, DNA unique to one newly created human person in even the one cell that is created when the male and female gametes join together. This is, truly, “human life”, in its absolutely most basic form. Undifferentiated, one single cell (which will immediately start dividing into two, four, eight, sixteen…), but still human life. What else could it be?
I do not, however, see how any of the quotes you cited state, or even imply, that this one cell (or two, or four…) has an immortal human soul, the same soul it will have for all eternity, and that this soul is created at the very instant of conception. That
may be true, but we do not
know that.
My “source” is countless instances of this teaching (or rather, lack of teaching) in 40+ years of being a Catholic. I’ve done a lot of reading, and 40+ years is a long time. I don’t memorize the exact place where I read everything. Are you suggesting that the Church, via the CCC, has
finally declared it to be a doctrine (or even dogma) that the soul is infused at that very instant of conception? Can other CAF readers confirm this?
I mean no hostility or confrontation. I grant your good faith, and I hope you will grant mine. I concede that it very well may be true, but that we cannot prove it, the Church cannot prove it,
no one can prove it. And I certainly
don’t suggest that abortion is ever acceptable because “it probably doesn’t have a soul that early”. The doubt, if there is one — and there is —
has to be settled in favor of life and ensoulment.
