How can you be a Christian and condone abortion? It's pure evil, murder of completely innocent life and this position is not in dispute among Christians.
There is no hard stance against abortion in the scripture. If anything it is permitted (and committed) by God in Numbers. The best argument I've seen from anyone quoting scripture is purely based on interpretation not any sort of biblical inerrancy.
If you are aware of the religious history of abortion you would know that Christianity did permit abortion in the middle ages, they also did not believe in the soul at conception.
So ironically I'm an old fashioned Christian in this case.
