I'm not asking for super secret quest news or anything here, just information that may leak out normally through clergy or things the churches would want known by the people of the lands.
I'm sure you Sunday bulletin at church is full of little notes about the community: A death here or there, an anniversary, a fund raiser, etc. Think of this as a way to set the tone of your deity's church in the eyes of the adventurers. Or use it to organize yourselves a bit better and share information.
