John Calvin on Abortion

"...for the fetus, though enclosed in the womb of its mother, is already a human being, and it is almost a monstrous crime to rob it of the life which it has not yet begun to enjoy. If it seems more horrible to kill a man in his own house than in a field, because a man's house is his place of most secure refuge, it ought surely to be deemed more atrocious to destroy a fetus in the womb before it has come to light." John Calvin (1509-1564), Commentary, Exodus 21:22 (posted on An Infant in A Cradle blog)
