FreeDuck, I do agree that Jesus would have mercy on a woman who did get an abortion for her choice.
dauer, okay back on topic (though i'm sure i and others will stray again).
As far as the argument that Jesus never addressed abortion:
I know that at no point is the newly conceived human not alive. They are always alive. They are always human. Suck the DNA out of a cell of a zygote, and you will see that that zygote is 100% human. Jesus said to do unto others as you would have them do unto you. I think that killing someone would fall under a bad thing using this rule.
So that's what I think. I'm still enjoying this thread and reading the other thoughts and opinions even if they differ.
