Sorry it's been about a year since I last played this game.
Both of those are correct.
I am assuming you have Katelyn in your party and you started this when you talked with her in the castle chapel. (Just making sure, not implying anything)
This is the order of events that usually happens:
1. Talk with Katelyn in the chapel (After Bath Room Scene)
2. Visit Summeredge church - Sile greets you when entering
3. Talk with Chalum after Sile - he mentions "Purple Moon"
4. Talk with Modus at Summeredge University - He provides you with Viridium
5. Return to Summeredge church and enter the room downstairs (not with the nun, it is towards the other end from where you enter on the left)
6. Kill enemy - quest completed
(Just want to make sure you have gone through each of these steps)
If you want you can just go to the downstairs room and kill the demon - getting the Viridium is actually optional.
One other thing - have you tried talking with Chalum while actually having Katelyn in your main party? (I noticed you have Xyless, Succubus, & Ruksana in the picture.)
Some dialogue only happens if the specific character is active (In one of the four available slots). I don't think I ever tried this one without having her in my party, so I don't know if it is a requirement or not, but I am starting to suspect that it is. If you haven't, try it with her in your active party and let me know if that makes any difference.
BTW: I agree - it does just look like a library.
