When was there a reference that not all druids had magic?

I certainly don't remember it.

But Mordred wasn't Cerdan's son, he was a druid because "Druids seek out children with magically or telepathic gifts as their apprentices", so that goes to show that all druids have magic and it is not something that is inherited.
