I received a communication from the Newsy.com site, and a suggestion I link to their 160-second piece summing up major reaction to the 2010 Nobel Prize for Medicine.
One thing that caught my ear was the assumption that a fertilized egg has a soul and this is the reason for Catholic moral opposition to IVF. That’s not quite true.
On one hand, a fertilized egg is not yet a unique human being. It still has the potential to split into twins, triplets, or such. And even twins at a very early stage in embryonic development have a chance to merge into one individual.
However, the Catholic moral position against IVF is based on respect for human life. Embryos may not yet be individual persons, but they are human life. Newsy does underscore the main public objection: the storage or discarding of, or experimentation with human enbryos.
