Candice didn't want to talk to her, but she knew that refusing would lead to trouble. Just as Teresa had sensed, Candice had stopped treating her with the confidence she once had in her.
This had nothing to do with her divinity as it happened inside the Marquis' office. The reason she no longer trusted her as much as before was due to the way Teresa acted when they were in the office.
Candice knows that Teresa is an intelligent woman. While it's true that she doesn't mix much in politics or business, it's not because she can't, it's just because she doesn't want to.
She knows that Teresa is more than just the wife of Marquis Valoide. Very few know it, but Teresa is the support of the Marquis and not in the spiritual or loving sense, but literally.
