"It can be hard to pick a martial arts school, because the teacher at almost any of them can beat you up as a novice, and you're too much of a beginner to figure out which of the teachers can beat up the other teachers. Someone who tries to explore theology seems to have a similar problem. What kinds of questions do you think are the equivalent of "cage matches" between different faith traditions? Do novices have a reasonable chance of reasoning to the correct tradition? If not, does that present problems for your soteriology?"
