The Didache describes the way of life: The way of life is not the way of murder, adultery, sodomy, fornication, theft, the use of magic and aphrodisiacs, infanticide and abortion. “Thou shalt not murder a child by abortion.”
Barnabas - declaring the way of life: "Thou shalt love thy neighbor more than thine own soul. Thou shalt not murder a child by abortion, nor again shalt thou kill it when it is born. Thou shalt not withhold thy hand from thy son or daughter, but from their youth thou shalt teach them the fear of God."
Clement (190 AD) - "Our whole life can go on in observation of the laws of nature, if we gain dominion over our desires from the beginning and if we do not kill, by various means of a perverse art, the human offspring, born according to the designs of divine providence; for these women who, in order to hide their immorality, use abortive drugs which expel the matter completely dead, abort at the same time their human feelings.
Clement continues the main themes of the Christian community: "Abortion is killing human life that is under God’s care, design and providence."
Tertullian writes: "In our case, murder being once for all forbidden, we may not destroy even the fetus in the womb, while as yet the human being derives blood from other parts of the body for its sustenance. To hinder a birth is merely a speedier man-killing; nor does it matter whether you take away a life that is born, or destroy one that is coming to the birth. That is a man which is going to be one; you have the fruit already in the seed."
Hippolytus (AD 222) - "Women, reputed believers, began to resort to drugs for producing sterility, and to gird themselves round, so to expel what was being conceived on account of their not wishing to have a child either by a slave or by any paltry fellow, for the sake of their family and excessive wealth. Behold, into how great impiety that lawless one has proceeded, by inculcating adultery and murder at the same time!"
