I would tend to distinguish between a caesarean section and actually growing a child outside of the womb. The former is a life-saving procedure when there are complications, the latter is really an attempt to replace the whole natural process of carrying a child in the womb, and thus an attack on the family unit. I think what we have to ask when we look at the progress of technology and science is not only whether or not the thing is good or bad in itself, but what it will lead to? I'm sure there's a scripture for it which would it would be better to reference, but I tend to think of Pandora's Box. What will come out of it? Mankind in general never asks these questions as they rush forward in the name of 'progress', but the believer ought to test these things.It is no more evil than a cesarean section or any other medical advancement.
