We are preparing our characters for the Way of the Wicked campaign and we should choose one of the crimes which is connetct also to some trait bonus. I was thinking about Heresy which has this benefit:
You receive a +1 trait bonus on all saving throws against divine spells.
Will it also apply against divine spell-like abilities?
Spell-like abilities functions just like spells:
Usually, a spell-like ability works just like the spell of that name. A spell-like ability has no verbal, somatic, or material component, nor does it require a focus. The user activates it mentally. Armor never affects a spell-like ability's use, even if the ability resembles an arcane spell with a somatic component.
A spell-like ability has a casting time of 1 standard action unless noted otherwise in the ability or spell description. In all other ways, a spell-like ability functions just like a spell.
Spell-like abilities are subject to spell resistance and dispel magic. They do not function in areas where magic is suppressed or negated. Spell-like abilities cannot be used to counterspell, nor can they be counterspelled.
If a character class grants a spell-like ability that is not based on an actual spell, the ability's effective spell level is equal to the highest-level class spell the character can cast, and is cast at the class level the ability is granted.
(Paizo PRD bolded by me).
Also here is official answer that some spell-like abilities are divine.
