This passage especially makes me wish that I could hear Anne's tone because I do believe she thinks that she's a sinner (as most Christians would say they are) but the implication here is that Anne is a sinner because of the way she practices her faith, which Anne probably wouldn't have said unless she were under duress.

I think this is a really great example of Anne's sola scriptura approach to her faith. Under questioning, she maintains her commitment to scripture alone as the source of God's direction.
