Any Way for a Druid or Oracle to Get an Aura Like a Cleric?

[Dr. Johnny Fever]

So as I look at the Sacred Summons feat I notice it has a requirement of an aura, like a Cleric's Aura. Is there any (Paizo Published) way for a Druid or an Oracle to get such an aura and qualify for this feat?

Thanks!

Typically a 1 level dip in Cleric or Paladin.

There is also a prestige class that grants such an Aura, but it requires 3rd level arcane spells.

You can also become a Hellknight Signifier, which grants an Aura of Law.
