I’m possibly a little late; I see that several good points have been mentioned by other people. I was doing some research. I thought that it might be interesting for people to see some of the actual quotes.
Some of the earliest surviving Christian writing is rather dense, and can take 2 or 3 read-throughs to fully grasp it; how much of that is due to translations issues, I have no idea.
1st quote:
“Thou shalt not slay the child by procuring abortion; nor, again, shalt thou destroy it after it is born.”
The Epistle of Barnabas, chap. 19 (from Ante-Nicene Fathers vol. 1)
From the Introductory Note–
“The writer of this Epistle is supposed to have been an Alexandrian Jew of the times of Trajan and Hadrian.”
2nd quote:
“Who does not reckon among the things of greatest interest the contests of gladiators and wild beasts, especially those which are given by you? But we, deeming that to see a man put to death is much the same as killing him, have abjured such spectacles. How, then, when we do not even look on, lest we should contract guilt and pollution, can we put people to death? And when we say that those women who use drugs to bring on abortion commit murder, and will have to give an account to God for the abortion, on what principle should we commit murder? For it does not belong to the same person to regard the very foetus in the womb as a created being, and therefore an object of God’s care, and when it has passed into life, to kill it; and not to expose an infant, because those who expose them are chargeable with child-murder, and on the other hand, when it has been reared to destroy it.”
A Plea for the Christians, chap. 35, by Athenagoras (AD133-190) Note: Athenagoras addressed this book to the Emperors Marcus Aurelius Anoninus and Lucius Aurelius Commodus.
(from Ante-Nicene Fathers vol. 2)
3rd quote:
“How, then, is a living being conceived? Is the substance of both body and soul formed together at one and the same time? Or does one of them precede the other in natural formation? We indeed maintain that both are conceived, and formed, and perfectly simultaneously, as well as born together; and that not a moment’s interval occurs in their conception, so that, a prior place can be assigned to either. Judge, in fact, of the incidents of man’s earliest existence by those which occur to him at the very last. As death is defined to be nothing else than the separation of body and soul, life, which is the opposite of death, is susceptible of no other definition than the conjunction of body and soul. If the severance happens at one and the same time to both substances by means of death, so the law of their combination ought to assure us that it occurs simultaneously to the two substances by means of life. Now we allow that life begins with conception, because we contend that the soul also begins from conception; life taking its commencement at the same moment and place that the soul does.”
A Treatise on the Soul, chap. 27, by Tertullian (155-225/240)
(from Ante-Nicene Fathers vol. 3)
4th quote:
“And I see that you at one time expose your begotten children to wild beasts and to birds; at another, that you crush them when strangled with a miserable kind of death. There are some women who, by drinking medical preparations, extinguish the source of the future man in their very bowels, and thus commit a parricide before they bring forth. And these things assuredly come down from the teaching of your gods. For Saturn did not expose his children, but devoured them. With reason were infants sacrificed to him by parents in some parts of Africa, caresses and kisses repressing their crying, that a weeping victim might not be sacrificed. . . . To us it is not lawful either to see or to hear of homicide; and so much do we shrink from human blood, that we do not use the blood even of eatable animals in our food.
The Octavius, chap. 30 by Minucius Felix (died c.250)
(from Ante-Nicene Fathers vol. 4)
Note: “parricide” is the killing of a close relative.
5th quote:
“And the hearers of Callistus being delighted with his tenets, continue with him, thus mocking both themselves as well as many others , and crowds of these dupes stream together into his school. Wherefore also his pupils are multiplied, and they plume themselves upon the crowds (attending the school) for the sake of pleasures which Christ did not permit. But in contempt of Him, they place restraint on the commission of no sin, alleging that they pardon those who acquiesce (in Callistus’ opinions). For even also he permitted females, if they were unwedded, and burned with passion at an age at all events unbecoming, or if they were not disposed to overturn their own dignity through a legal marriage, that they might have whomsoever they would choose as a bedfellow, whether a slave or free, and that a woman , though not legally married, might consider such a companion as a husband. Whence 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!”
The Refutation of all Heresies, Book IX, chap. 7 by Hippolytus (170-236)
(from Ante-Nicene Fathers vol. 5)
From the Contents of Book IX–
“And how Callistus, intermingling the heresy of Cleomenes, the disciple of Noetus, with that of Theodotus, constructed another more novel heresy, and what sort the life of this (heretic) was.”
In other words, Hippolytus is describing a certain heretic named Callistus, and how his teachings and practices differed from the early Christians.
