I wonder what the other Codex chapters will be about. There's almost certainly going to be a New Eden chapter, which has everyone remain naked because of course it will, but that probably won't be the next one, considering chapter 4 hits 50 corruption, implying we've got a few more levels to go.
Maybe a New Earth chapter will come first? I recall a passage in the Bible where the Pharisees try to trick Jesus into blasphemy by presenting the following circumstance:
"A man with many brothers has married a woman, but dies leaving her childless. According to Moses, it is the responsibility of the man's brothers to marry that woman and give her children. So one of the brothers marries the woman, but also dies before giving her a child. This process continues, with brothers marrying the woman and dying before giving her a child, until all the brothers have died. Then the woman died. When the resurrection of man comes, to whom is the woman married to?"
To which Jesus responds "You won't trick me like that; marriage is an institution of this Earth. It will not exist in the new world that is to come."
I can see this being used to justify having casual sexual encounters without using the rite of Holy Marriage.
