Justin Martyr c. 100–c. 165 ADFirst Apology 27

And just as the ancients are said to have kept herds of oxen or goats or sheep or grazing horses, so now children too are kept only for shameful use; and likewise a multitude of females and of hermaphrodites and of doers of unspeakable things stands ready in every nation for this pollution.

Justin is denouncing the exposure of infants, a pagan practice, because exposed children are raised for prostitution. He calls the trade a pollution (ἄγος) and contrasts it with the Christian teaching that exposing children is wicked.

Athenagoras fl. c. 177 ADPlea for the Christians 34

For they have set up a market of prostitution and made unlawful resorts for the young for every shameful pleasure, not sparing even males, males working the dreadful things with males, and in every way outraging the bodies that are more modest and beautiful, dishonouring the fair work of God.

Athenagoras turns the pagans' slanders back on their authors: adulterers and pederasts, he says, revile Christians, who live as eunuchs and in single marriage.

Clement of Alexandria c. 150–c. 215 ADThe Instructor 2.10.83

Seed, the substance that begins generation, must not be outraged, since it has the principles of nature sown in it; and to bring shame on the natural principles by turning them unreasonably to unnatural ways is utterly godless.

Clement's argument from nature, close to the Stoics, covers all non-procreative acts.

John Chrysostom c. 349–407 ADHomilies on Romans 4.2, on Romans 1:26–27

What women who prostitute themselves suffer, these suffer too, or rather something more wretched. For with them, even if the union is unlawful, it is according to nature; but this is both unlawful and against nature.

Chrysostom notes that Greek law and philosophers had tolerated such relations.

Augustine of Hippo 354–430 ADConfessions 3.8.15

So the shameful acts that are against nature, such as those of the Sodomites, are everywhere and always to be detested and punished. Even if all nations did them, they would all be held guilty of the same crime by God's law, which did not make human beings to use one another in this way.

Augustine contrasts acts wrong by custom with acts wrong everywhere.
