You are very welcome. And, thank you. I wrote it. It describes what I believe the Bible is telling us about the true nature of 'the church' and 'churches'.
I understand. What I believe is, in a way, similar to what you describe here; only, with some difference(s).
Using what is written on that web page in a relative comparison to "the kingdom", let me suggest that:
(From your point of view, in "kingdom" terms.)
~ The 'spiritual' [church] represents the kingdom that you have been describing - as a spiritual [invisible] kingdom that exists currently, and has existed since it began in the first century.
~ The 'universal' [church] represents the kingdom that most everyone else is describing - as a physical kingdom that will exist for 1000 years starting at some point in the future.
Would you say that this is accurate to any reasonable degree?
