の substituting が in relative clauses

[Sakide]

'Sup.
Today I want to ask about a grammatical peculiarity which I've noticed quite a lot in my years of Japanese-learning.
I sometimes come across relative clauses, or more specifically attributive verbs, which are preceded by a の even though I'd use a が there. What's that の doing there?

Some examples (from pop culture, since I can't remember any better ones):

• 神様のいない日曜日
• ひぐらしのなく頃に

What's the difference between that and things like, say, 母が作ったパン or 両親がいない人?
Are が and の interchangeable here? What's the difference exactly if you use が or の?

の and が are interchangeable except when a noun follows right after it, and there is no difference in meaning between them. See the following thread.

ありがとうございました！

Just ました！ doesn't make sense, or at least it's quite hard to understand even after ありがとうございました！ in the thread linked above.

This was because the ました was supposed to go into the other thread. Dunno how it ended up here. xD
I say:

This was because the ました was supposed to go into the other thread.

And I pointed out that it doesn't make sense even for the case.
