Example; Christians believe that life starts at conceptions.
That's a bit of a generalisation.
Not all christians believe that.
It's certainly a key belief within Roman Catholocism, hence their disapproval of contraception and abortion.
Not all denominations of christianity believe life begins at conception.
That's also true of christians who don't belong to any 1 specific denomination.
There are many who believe that life begins when the child is born, or when the child is capable of living outside of the womb, or when the foetus first develops a heart, brain or spinal cord.
While religion does provide a basis for a persons view upon whether abortions are acceptable or not, the more prominent belief to question is at what point in embryological development does someone believe life begins at.
If you are of the view that abortion is the killing of a human, then that view is incredibly dependant upon when you believe the embryo/foetus is officially living, and is therefore human.
i don't imagine there's a single dang thing in the bible about abortions because it wasn't even viable at the time of the lawd
I'm pretty sure that the common passages that are used to defend against abortion are ones used for other such things.
Including the sanctity of life;
"Genesis 1:27 So God created man in his own image, in the image of God he created him; male and female he created them."
"Deuteronomy 30:19 This day I call heaven and earth as witnesses against you that I have set before you life and death, blessings and curses. Now choose life, so that you and your children may live and that you may love the Lord your God, listen to his voice, and hold fast to him. For the Lord is your life..."
Aswell as the sanctity of a man's seed;
" Genesis 38:9-10
But Onan knew that the offspring would not be his. So whenever he went in to his brother's wife he would waste the semen on the ground, so as not to give offspring to his brother. And what he did was wicked in the sight of the Lord, and he put him to death also. "
