An innocent life which is not even born? A life which has experienced nothing, knows nothing, and which loses nothing more then a seed and an egg dispatching into a dead end..
The legal argument fails considerably. And make no mistake, that's what your standing is- a legal fiction:
You define life in a completely different way until the subject of fetuses arise. And that's been a problem throughout the centuries, apparently, as church leaders have failed to agree through history.
The most prevalent of the cases for abortion is that life doesn't begin until the explicit animation of the fetus- that is, when it moves. That is when the supposed spark of the soul comes to be: the moment of the soul's action in reality.
See the legality there? It doesn't mesh with what is otherwise considered human life, in which one is autonomous and perceiving, and experiencing.
You see this with Adam, when God did precisely that. He wasn't born from a womb, he breathed life and upon so, became a living soul.
The reason abortion is sinful is because it is generally disgraceful. It is an unnatural act not intended for us to do. Like homosexuality.
It's a subject of natural law, not murder.
So were all the saints who were martyred by Christendom and later canonized.
It's an odd position to think the Church is always inerrant when, first and foremost, admits it is not AND realizes it's mistakes by doing things such as ~canonizing once assumed heretics~.
You do not see the unborn baby as an innocent person worthy of protection ... got it. Actual prolife advocates DO see the unborn as innocent human beings.
