Pretending to be an Athiest to Catch an Athiest who is not an Athiest

The men of the week are pretending to be someone they are not to catch someone they don't understand. The jist of what they are doing sounds pretty simple, going undercover to capture the criminal, but it is because they assume it's that simple that they do not understand the 'criminal', who is no criminal at all but the fulfiller of their purpose. So by having the someone they don't understand tell them to be someone they are not so they can catch the person they don't understand, they then finally find who they really are.
