When a person believes a certain interpretation of scripture, he can "understand" and "explain" it. Other, equally valid or even more valid, ways of looking at it are hidden if they don't reinforce the investment he has made, especially if his spiritual salvation depends on the interpretation.
My responses are reasoning, much like Jesus or a disciple "reasoned" over scripture with a rabbi or scribe. Not all things are found in scripture, so implications must be reasoned out in light of the context, tradition and actual words.
This much is very plain to me. If Jesus, who knew things to come, was to award a human run organization the power over the very souls of men, who is accepted and rejected, who is saved or condemned, ways to address the Father that He didn't specifically say, the power and authority of God in judgment of how men think and act, His plan would have made it into scripture clear, unambiguous, and would have said specifically that with the clarity and specificity of ". . .kingdom of God is within."
I don't see how you've shown me that. You've shown me a Rube Goldberg device where there ought to be a hammer.
