That isn’t true. I don’t think it was ever actually true, but it certainly isn’t now. In Eberron, divine magic comes from faith.
Vol isn’t the center of worship, either. She’s the head of the main clerical structure of the faith, but most actual practice is based in ones community.
The Flame grants power because it is the combined souls and power of all the faithful who have ever died in service to the ideals of the Silver Flame, so it’s a bit different from any other faith in Eberron.
Even if we ignore what I wrote above, they aren’t “atheists”, they’re just atheists. They don’t believe the gods are real. The end. And they very well might be right.

And as much as you strip out, BadWolf, MD, you've got to realize that those things are a part of something you're stripping away to get at the bits you want and need.
And once you've stripped away enough that it's easier to describe what you -haven't- removed than what you -have- removed, you've gotta know you're not playing D&D at that point. Oh, you're using the d20 system at the heart of D&D. But it ain't D&D anymore.
