I've been enjoying questioning long held beliefs lately. One issue I've been pondering is the life of the unborn. This has been brought on by a couple of things.
Sam Harris in End of Faith and Letter to a Christian Nation discusses the moral implications of stem cell research and this has been discussed in the media lately too. He makes the argument that morals and ethics are primarily to do with human suffering. He weighs the potential suffering of a human embryo at 14 days (a blastocyst, a group of undifferentiated cells) against that of someone with a spinal injury who cannot walk who could potentially benefit from stem cell therapy in the future. He makes the point that the embryo has no nervous system at this age and there are more cells in the brain of a fly.
I accept the logic of his arguments and yet there is still something distasteful about the distruction of human life. My own opinions on this subject have changed and I now see the issue being discussed and solved based on scientific knowledge rather than the Bible and religious belief.
All this is a long winded preamble to my question which is this...
...Where exactly in the Bible does it say that life begins at conception? (Or in the catholic language - that the soul enters the zygote at conception)
I am aware of the scriptures in psalms about the embryo and all the parts down in writing but that's not quite the same as saying that life begins at conception. Also, I wonder about the original word that the WTBTS have translated as embryo. I doubt that the ancients new much about blastocysts.
I am also aware of the rules in the Torah regarding two men fighting and hurting a pregnant woman but again this does not necessarily mean that life begins at conception.
Finally, I think that any discussion of this should at least acknowledge that a large percentage of all pregnancies end in miscarriage. To quote Sam Harris "God is the greatest abortionist of all" I know that the WT would view this as a consequence of sin and corruption but it is hardly fair that an unborn child, who has not drawn breath let alone sin, bear the sin of Adam. I think that any reasonable discussion of the subject should take this into account.
I'm interested to hear opinions on this, but I would like to know an answer to where, if at all, this is stated in the Bible.
