Interesting presentation of an interesting idea. I am more used to presentations using the gospels as texts containing not-always-obvious esoteric teaching, and am not used to Paul being presented as a teacher of esoteric principles, but I found the idea intriguing.
Do you happen to know what greek word was being used for the translated word "love" in this Corinthians text? Agape?
I would certainly agree that the universal love teaching of the christian system is, arguably christianity's greatest contribution to the minds of this planet, and that it is incredibly important as a method and orienting guide in our times and for our dilemma.
However, exactly how that universal love is to first, be attained, and second, be manifest and foundational, and third, be maintained, is not yet a clear part of our collective effort.
