1. The worship of God through Jesus does not need an organization. There is a danger when praise and or worship that should be directed to God becomes shared with an organization. That is idolatry.
The approach to God is through Jesus not through a secondary mediator.
An organization can serve a purpose, bringing together people of various talents and abilities but can become a dangerous thing if gone unchecked. The organization can become the end rather a means to an end.
We should seek fellowship with other Christians (coming to this forum is one way). Matt 18:20 says "For where two or three are gathered together in my name, there I am in their midst." (Hi JC)
But the gathering or group ought to serve Christians not insert itself between fellow Christians and Christ.
2. Jesus Christ would not submit himself to a ritual that puts an organization on the same level as himself and his father. They would not baptize him unless he agreed to answer YES to their silly questions.
