Excellant thread.
One aspect that is stumblying and which the organization uses today is the original earthly nation that God established a covenant with to become his people. Worship seemed to be more of a physical display rather than emotional, with written laws to be obeyed, sacrifices, fistivals and a temple. God required this showy display of worship. Was worship an emotional thing to them? Maybe that is why they were not successful in God's eyes and why Jesus needed to bring in a new covenant, one that was attainable for imperfect human. Once we appreciate and understand that worship is an emotion which comes from the heart we can be assured that this is God's will.
What the organization has done, is set itself up as a new earthly Israel on the pretence that it is a spiritual Israel. This is demonstratable on many levels but most significantly by excluding the great crowd of other sheep as being excluded from the spiritual Israel.
