Assuming I'm using the Spontaneous Cleric Variant and there's an Initiate of [some deity] which grants some special spells (only when this feat is taken) and the spontaneous cleric takes that feat when he gains a lvl…
Extra known spells? Or can you now choose these spells as if those were from your standard cleric list?
The second one seems like the neatest rule understanding…
I'm looking for answers by RAW and by deduction in case those are different.
@Edit: Favored Soul!
As a matter of fact, the original issue is that the char taking the feat is a favored soul which at first sight is not a Cleric (nor a Paladin) pre-Reqs of "Initiate of" tier feats. However the DM is convinced that for this purpose he would take the Favored Soul as a Cleric of the same lvl.
