Quotes from some early church fathers

Athenagoras (177-180)
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. (A Plea for the Christians, 35)

Justin Martyr (d. 165)
writings (153-160?) martyred
And when you hear that we look for a kingdom, you suppose, without making any inquiry, that we speak of a human
kingdom; whereas we speak of that which is with God, as appears also from the confession of their faith made by those
who are charged with being Christians, though they know that death is the punishment awarded to him who so confesses.
For if we looked for a human kingdom, we should also deny our Christ, that we might not be slain; and we should strive to
escape detection, that we might obtain what we expect. But since our thoughts are not fixed on the present, we are not
concerned when men cut us off; since also death is a debt which must at all events be paid. (I Apology, 11)
And when the Spirit of prophecy speaks as predicting things that are to come to pass, He speaks in this way: "For out of
Zion shall go forth the law, and the word of the Lord from Jerusalem. And He shall judge among the nations, and shall
rebuke many people; and they shall beat their swords into ploughshares, and their spears into pruning-hooks: nation shall
not lift up sword against nation, neither shall they learn war any more." And that it did so come to pass, we can convince
you. For from Jerusalem there went out into the world, men, twelve in number, and these illiterate, of no ability in speaking:
but by the power of God they proclaimed to every race of men that they were sent by Christ to teach to all the word of God;
and we who formerly used to murder one another do not only now refrain from making war upon our enemies, but also,
that we may not lie nor deceive our examiners, willingly die confessing Christ.

Tatians (164) - Address to the Greeks, sect. XI
I do not want to be a king: I do not wish to be rich: I decline military service: I hate fornication.
