Cure clue?

Am I totally misunderstanding this line or did Theophanie reveal a Venin cure (or at least some way to neutralize them)?

Ch 64, pg. 736 (last sentence in this exchange between her an Vi): “Do you not yearn for temple?” I use the words the high priestess had on me. Her face twists with an emotion that almost looks like longing, but it’s quickly masked with anger. “Do you?” she counters. “Or are you immune, having only been touched, but not dedicated?” She charges forward. “Do you know the pain of never being allowed to return, of knowing that it would sever the very thing that’s kept me untouchable all these years?”

Is she saying that by going into Dunne's Temple in Unnbriel that she'll lose her Venin powers? It wouldn't be that obvious/easy right???
