374 AD, Basil the Great:
- "Let her that procures abortion undergo ten years' penance, whether the embryo were perfectly formed, or not" (First Canonical Letter, canon 2).
- "He that kills another with a sword, or hurls an axe at his own wife and kills her, is guilty of willful murder; not he who throws a stone at a dog, and unintentionally kills a man, or who corrects one with a rod, or scourge, in order to reform him, or who kills a man in his own defense, when he only designed to hurt him. But the man, or woman, is a murderer that gives a philtrum, if the man that takes it die upon it; so are they who take medicines to procure abortion; and so are they who kill on the highway, and rapparees" (First Canonical Letter, canon 8).
"Wherefore I beseech you, flee fornication . . . Why sow where the ground makes it its care to destroy the fruit?--where there are many efforts at abortion?--where there is murder before the birth? For even the harlot you do not let continue a mere harlot, but make her a murderess also. You see how drunkenness leads to prostitution, prostitution to adultery, adultery to murder; or rather to a something even worse than murder. For I have no name to give it, since it does not take off the thing born, but prevents its being born. Why then do thou abuse the gift of God, and fight with His laws, and follow after what is a curse as if a blessing, and make the chamber of procreation a chamber for murder, and arm the woman that was given for childbearing unto slaughter? For with a view to drawing more money by being agreeable and an object of longing to her lovers, even this she is not backward to do, so heaping upon thy head a great pile of fire. For even if the daring deed be hers, yet the causing of it is thine" (Homilies on Romans 24).
396 AD, Jerome:
"I cannot bring myself to speak of the many virgins who daily fall and are lost to the bosom of the Church, their mother . . . Some go so far as to take potions, that they may insure barrenness, and thus murder human beings almost before their conception. Some, when they find themselves with child through their sin, use drugs to procure abortion, and when, as often happens, they die with their offspring, they enter the lower world laden with the guilt not only of adultery against Christ but also of suicide and child murder" (Letters 22:13).
400 AD, The Apostolic Constitutions:
"Thou shalt not use magic. Thou shalt not use witchcraft; for He says, 'You shall not suffer a witch to live' [Ex. 22:18]. Thou shall not slay thy child by causing abortion, nor kill that which is begotten; for "everything that is shaped, and has received a soul from God, if it be slain, shall be avenged, as being unjustly destroyed." (Apostolic Constitutions 7:3).
