Well, there are two kinds of heretics. There's the kind that strips naked and howls at the moon, and there's the kind that does the same thing in Vocis's living room. The first one he can ignore, the second one he kinda has to deal with. 
Put more simply, Vocis doesn't care how or who Adan (or anyone) worships until it causes problems Vocis has to address.
As for the details of the scriptorium, I have to admit that I'm only loosely familiar with the bookbinding rules in Covenants and not at all familiar with the workshop rules from C&G. I must also admit I'm not that interested in learning more about them. So Silveroak, how about this - you look at the scribes we have and tell me what they're capable of copying and/or improving in a given season. Given that framework, I (Vocis) will prioritize what will be copied and when, with input from you (Adan) and Trogdor (Lucas, Assistant Librarian) and addressing requests from other members as they arise. Note that Lucas has two mundane scribes on his 'sanctum' payroll that we'll also need to account for. We're assuming they can only copy mundane books, but Marko will need to decide what their Prof: Scribe level is.
On a related note, we never finalized the cross-saga trade we discussed over PM. After reviewing it, I think you and Marko need to find a solution for resolving the two different valuation mechanics involved. The framework of the deal is basically complete, but I can't make mechanical decisions like that.
