John Calvin on Abortion

"The fetus carried in the mother's womb is already a man; and it is quite unnatural that a life be destroyed of one who has not yet seen its enjoyment.

For it seems more unworthy that a man be killed in his home rather than in his field because for each man his home is his safest refuge. How much more abominable ought it to be considered to kill a fetus in the womb who has not yet been brought into the light."
