Ok, I am not sure exactly where to go with this so I'll give the backstory a little. I've never created anything like this before and I don't really know where to start
In an older campaign I had a bard character that became the hero of a town and the town was renamed after him. A couple centuries later in my current campaign, my character is one of the descendants of this Bard (named Raines) and Raines is worshiped by some as a god in those lands. I'm looking to create a couple different alternate classes based on this church
The main idea
Arcane spellcasters that believe their arcane powers are given from a divine source(Raines)
Things I'm trying to come up with
Arcane versions of the Paladin, Inquisitor and Cleric as representatives of the church
Have you seen a witch? It is arcane caster that prepares spells that learns her spellcasting ability from a mysterious patron and stores her spells in her familiar (who is also her link with the patron). There is an archetype that replaces familiar with bonded item in one of the accessory books (Ultimate Magic? Advanced Race Guide? I don't remember at the moment).
