Basil: "The destruction of the embryo"

 II. "THE woman who purposely destroys her unborn child is guilty of murder. With us there is no nice enquiry as to its being formed or unformed. In this case it is not only the being about to be born who is vindicated, but the woman in her attack upon herself; because in most cases women who make such attempts die. The destruction of the embryo is an additional crime, a second murder, at all events if we regard it as done with intent. The punishment, however, of these women should not be for life, but for the term of ten years. And let their treatment depend not on mere lapse of time, but on the character of their repentance."

~St. Basil of Caesarea: "Letters," 188, To Amphilochius, concerning the Canons.

St. Basil the Great of Caesarea:
"Bishop of Caesarea, and one of the most distinguished Doctors of the Church. Born probably 329; died 1 January, 379. He ranks after Athanasius as a defender of the Oriental Church against the heresies of the fourth century. With his friend Gregory of Nazianzus and his brother Gregory of Nyssa, he makes up the trio known as "The Three Cappadocians", far outclassing the other two in practical genius and actual achievement."
