Theurge Archivist Wizard with Alternative Source Spell

[schreier]

In this setup, with a spellbook and prayer book .... can you memorize any arcane spell as a divine using the metamagic, then put it directly into the prayer book as if writing into a backup spellbook? Do you need to put it on a scroll first (costing xp)? Can you reverse it? I'm guessing not, since arcane does not mean it's on the wizard class spell list.

Not only can you put it in your prayerbook, but if some other non-theurge archivist comes along, he can copy it into his prayerbook, too. At least, if you play it by RAW, but that's a powerful enough combination (it means that an archivist can get all the spells) that a DM might well houserule it away.
