The Problem of Evil revisited…

The late Mennonite theologian, John Howard Yoder (to be sure a fallen man himself), crtitiqued theodicy with the following questions. I’d like to hear from both the theists and atheists on this site what their responses are to his questions:

a) Where do you get the criteria by which you evaluate God? Why are the criteria you use the right ones?

b) Why [do] you think you are qualified for the business of accrediting God/s?

c) If you think you are qualified for that business, how does the adjudication proceed? [W]hat are the lexical rules?
