Thank you, Bob:

I was very interested to learn, in much more detail, what the Pope and
his advisors, if you will,  had to say about the various therapeutic
techniques, and not just the recent Papal edict forbidding fetal or
embryonic uses in medicine.  Also, I thought it was very well written,
and points out how really murcky the comparisons are, of one therapy,
say, bone marrow donation for example, and another therapy, say, stem
cells donated from remaining embryos after in vitro fertilization.  I
really feel the latter is life from life.  A couple, who has been unable
to have a child, happily is able to have a family;  but to be
successful,  must produce a surfeit of fertilized eggs only a few of
which can be implanted.  If they choose to donate the remaining embryos
to save and/or repair a life, that surely is: an act of love, and the
same as organ transplantation, of which he approves.  The only
difference is, in the latter, that organ donation is usually, sadly,
from the death of another human being.  Embryonic donation is, in my
view, surely life from life.  It must be made clear, that the sole
purpose of  creating the excess fertilized eggs, is to ensure the
successful birth of a child.  The therapeutic use of stem cells
extracted from the remaining embryos is simply a very fortunate
consequence of this happy event.  They were not created to be destroyed
for therapeutic research, but to ensure a successful birth!  Is the Pope
against a birth brought about in this way, because it results in
left-over embryos that are then discarded?  If not, then there is
something very wrong with the Papal analysis of what is taking place.

Thanks for the opportunity to respond to this interesting article.
