My Christian faith has taught me life begins at conception.
christianity has been going back and forth on this for two millenia, and will undoubtably go back and forth for two more millenia. the list of sage-status christians who held conception is NOT the beginning of life in any meaningful sense is longer than the list of those who did.
from the Old Testament...
you're referring it as "the old testament" while talking with a Jew? ;)
