For the fetus, though enclosed in the womb of its mother, is already a human being, and it is 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
How great, therefore, the wickedness of human nature is! How many girls there are who prevent
conception and kill and expel tender fetuses, although procreation is the work of God.
--Martin Luther, Luther's Works, American Ed., (St. Louis: Concordia Publishing), v. 4, 304.
