Defense-From-Anathema Method/Dragon's Parable Defense has a bit of a strange history to it. The original wording in 1e and 2e Dragon-Blooded simply stated that it worked against "Anathema," and didn't really go into any detail on what counted for that. When the Dragon-Blooded got the large errata overhaul that came with Thousand Correct Actions of the Upright Soldier, it got a clarification that explains that it worked against all creatures of darkness, plus Celestial Exalted, to cover Solar and Lunar Anathema. That was probably how most groups would run it, so it made sense, but it then had to explain why
the holy protection charm would work against them. It attributed this to the Dragon-Blood tapping Gaia's primordial power and love as a shield. That introduces a lot of weird setting stuff (can I shut down Defense-From-Anathema by killing Gaia?) and also is pretty far away from the paradigm of how Terrestrial Charms work. So, when the Dreams of the First Age errata came around, it talked about how Defense-From-Anathema Method was known as Dragon's Parable Defense, like you described.
That's sort of a twisted and tangled history, and I wouldn't want to use that kind of stopgap retcon as a foundation moving forward (even though I personally thought it was very clever).
