Pathfinder Campaign Setting: Inner Sea Gods is the system that contains Evangelist.
Evangelist doesn't work for the align class aspect (at the very least with magus), which is pretty much the whole deal. It doesn't add class features correctly (such as magus arcana), it also doesn't do spell progression correctly for giving you new spell levels and spells for day.
It also gives Divine Boons if you look in the character sheet but it asks you to select boons in the things to be done tab (also I suppose it may be giving it via the feat so maybe it should be checked).
It gives you spiritual form on the character sheet nothing wrong there, I guess it would be convenient to add it to the temporary bonuses, but that's more suggestion than bug.
