Researching New Divine Spells

Or, acquiring new divine spells.

I tthought I read about this somewhere but can’t seem to find it now. How does replacing a divine spell with a newly researched one work?

Not an Autarch, but: p. 117, Researching Spells, fourth paragraph:

A cleric or other divine caster can only research a spell with the permission of his deity (Judge’s discretion). The deity will usually remove a spell of the same level from the cleric’s spell list in exchange for granting the new spell.

Thanks, Thomas! I found this and forgot to come back and let everyone know.
