What about this in the Didache?
The Didache, a second-century catechism for young converts, states, “Do not murder a child by abortion or kill a newborn infant” (Didache 2.2). Clement of Alexandria maintained that “those who use abortifacient medicines to hide their fornication cause not only the outright murder of the fetus, but of the whole human race as well” (Paedogus 2:10.96.1).
Defending Christians before Marcus Aurelius in A.D. 177, Athenagoras argued, “What reason would we have to commit murder when we say that women who induce abortions are murderers, and will have to give account of it to God? …The fetus in the womb is a living being and therefore the object of God’s care” (A Plea for the Christians, 35.6).
Tertullian said, “It does not matter whether you take away a life that is born, or destroy one that is coming to the birth. In both instances, destruction is murder” (Apology, 9.4). Basil the Great affirmed, “Those who give abortifacients for the destruction of a child conceived in the womb are murderers themselves, along with those receiving the poisons” (Canons, 188.2). Jerome called abortion “the murder of an unborn child” (Letter to Eustochium, 22.13). Augustine warned against the terrible crime of “the murder of an unborn child” (On Marriage, 1.17.15). Origen, Cyprian, and Chrysotom were among the many other prominent theologians and church leaders who condemned abortion as the killing of children. New Testament scholar Bruce Metzger comments, “It is really remarkable how uniform and how pronounced was the early Christian opposition to abortion.” [10]
