Under the Speaker for the Past Shaman archetype, it says this:
Mysteries of the Past: A speaker for the past......adds the spells from the ancestor and time oracle mysteries to her class spell list (at the cleric level for those spells).
However, many of the bonus spells are not on the cleric list. I see a few possible interpretations of this:
a) You only get the spells which are on the cleric list (like spiritual weapon) and not the ones which aren't (like time stop)
b) You get all the spells on these lists and the bolded quote is clarifying that you get the bonus spells at the class level that you begin to cast those level spells rather than the level after (as oracles begin casting X level spells 1 class level after clerics)
I'm hoping for option b (who wouldn't want to get disintegrate or time stop) but I would guess it's option a. I'd be open to other interpretations. Just wanted to get a second opinion.
