Justin Martyr – On the Resurrection: Chap. 7 – The body valuable in God’s sight:

For does not the word say, “Let Us make man in our image, and after our likeness?” What kind of man? Manifestly He means fleshly man, For the word says, “And God took dust of the earth, and made man.” It is evident, therefore, that man made in the image of God was of flesh. Is it not, then, absurd to say, that the flesh made by God in His own image is contemptible, and worth nothing? But that the flesh is with God a precious possession is manifest, first from its being formed by Him, if at least the image is valuable to the former and artist; and besides, its value can be gathered from the creation of the rest of the world. For that on account of which the rest is made, is the most precious of all to the maker.

Justin Martyr – The Martyrdom of Justin Martyr: Chap. 1 – Examination of Justin by the prefect: This is the beginning part of Justin’s testimony before Rusticus. His words here ring with similarity to that of Polycarp.

 And when they had been brought before his judgment-seat, said to Justin, “Obey the gods at once, and submit to the kings.” Justin said, “To obey the commandments of our Saviour Jesus Christ is worthy neither of blame nor of condemnation.” Rusticus the prefect said, “What kind of doctrines do you profess?” Justin said, “I have endeavoured to learn all doctrines; but I have acquiesced at last in the true doctrines, those namely of the Christians, even though they do not please those who hold false opinions.” Rusticus the prefect said, “Are those the doctrines that please you, you utterly wretched man?” Justin said, “Yes, since I adhere to them with right dogma.” Rusticus the prefect said, “What is the dogma?” Justin said, “That according to which we worship the God of the Christians, whom we reckon to be one from the beginning, the maker and fashioner of the whole creation, visible and invisible; and the Lord Jesus Christ, the Son of God, who had also been preached beforehand by the prophets as about to be present with the race of men, the herald of salvation and teacher of good disciples. And I, being a man, think that what I can say is insignificant in comparison with His boundless divinity, acknowledging a certain prophetic power, since it was prophesied concerning Him of whom now I say that He is the Son of God. For I know that of old the prophets foretold His appearance among men.”

The examination continues

The prefect says to Justin, “Hearken, you who are called learned, and think that you know true doctrines; if you are scourged and beheaded, do you believe you will ascend into heaven?” Justin said, “I hope that, if I endure these things, I shall have His gifts. For I know that, to all who have thus lived, there abides the divine favour until the completion of the whole world.” Rusticus the prefect said, “Do you suppose, then, that you will ascend into heaven to receive some recompense?” Justin said, “I do not suppose it, but I know and am fully persuaded of it.” Rusticus the prefect said, “Let us, then, now come to the matter in hand, and which presses. Having come together, offer sacrifice with one accord to the gods.” Justin said, “No right-thinking person falls away from piety to impiety.” Rusticus the prefect said, “Unless ye obey, ye shall be mercilessly punished.” Justin said, “Through prayer we can be saved on account of our Lord Jesus Christ, even when we have been punished, because this shall become to us salvation and confidence at the more fearful and universal judgment-seat of our Lord and Saviour.” Thus also said the other martyrs: “Do what you will, for we are Christians, and do not sacrifice to idols.”

Irenaeus – Against Heresies Book 1: Chap. 6 – Here, Irenaeus points out the abuse some of the teachers of the Valentinian Gnostic heresy have taken advantage of the women under their teaching.

Wherefore also it comes to pass, that the “most perfect” among them addict themselves without fear to all those kinds of forbidden deeds of which the Scriptures assure us that “they who do such things shall not inherit the kingdom of God.” For instance, they make no scruple about eating meats offered in sacrifice to idols, imagining that they can in this way contract no defilement. Then, again, at every heathen festival celebrated in honour of the idols, these men are the first to assemble; and to such a pitch do they go, that some of them do not even keep away from that bloody spectacle hateful both to God and men, in which gladiators either fight with wild beasts, or singly encounter one another. Others of them yield themselves up to the lusts of the flesh with the utmost greediness, maintaining that carnal things should be allowed to the carnal nature, while spiritual things are provided for the spiritual. Some of them, moreover, are in the habit of defiling those women to whom they have taught the above doctrine, as has frequently been confessed by those women who have been led astray by certain of them, on their returning to the Church of God, and acknowledging this along with the rest of their errors. Others of them, too, openly and without a blush, having become passionately attached to certain women, seduce them away from their husbands, and contract marriages of their own with them. Others of them, again, who pretend at first to live in all modesty with them as with sisters, have in course of time been revealed in their true colours, when the sister has been found with child by her [pretended] brother.

Irenaues – Against Heresies Book 1: Chap. 8 – This passage reminds me of 1 Peter 3:16 –

Such, then, is their system, which neither the prophets announced, nor the Lord taught, nor the apostles delivered, but of which they boast that beyond all others they have a perfect knowledge. They gather their views from other sources than the Scriptures; and, to use a common proverb, they strive to weave ropes of sand, while they endeavour to adapt with an air of probability to their own peculiar assertions the parables of the Lord, the sayings of the prophets, and the words of the apostles, in order that their scheme may not seem altogether without support. In doing so, however, they disregard the order and the connection of the Scriptures, and so far as in them lies, dismember and destroy the truth. By transferring passages, and dressing them up anew, and making one thing out of another, they succeed in deluding many through their wicked art in adapting the oracles of the Lord to their opinions.
