My "pet" idea was an explanation, through metaphor, of Christ's relationship to God and the Holy Spirit. It was based on the JW, non-Trinitarian concept of Representative Christology. Ready?
God was like a sun and the Holy Spirit (impersonal) was like the sunlight. Christ, the son of God (created as firstborn), was like a prism through which the light shone turning it into a rainbow. All the angels and perfect humans were like diamonds reflecting the light from the prism (Holy Spirit) their sparkling being the act of worship.
Fallen men were like dirty lumps of coal from which diamonds could be made when held under enormous pressure.
This belief in mind was in contrast to the JW metaphor in which an individual JW was like a piece of charcoal in a coal heap - all the JWs - which would die out unless it remained close to the others. Of course, this was an analogy which ignored the act of individual salvation in favor of group salvation which the Watchtower holds so dear.
I never wrote to Brooklyn, they would have just sent the letter to the local congregation. I did mention it to one of the elders who was later part of my judicial committee (For a reason that was unrelated to my disfellowshipping). The elder had used the charcoal analogy implying that I was getting too far away from the heap which represented the organization. I responded to that with my analogy which showed that being in proximity to others was not a prerequisite to salvation.
It's so good to be clear headed now. I don't waste my imagination counting angels on the heads of pins.
