My take on Walsh:
In the Walsh trial, they were trying to get a draft classification as minister for Walsh, who was young (about 20), a company servant, and a pioneer. They had decades of statements in the Watchtower going back to the Russell days that they were not an established religion, they didn't have a clergy, they didn't have a creed which their ministers had to adhere to. These things had been the barrier to getting any of the JWs recognized as a minister of a religion worthy of the minister classification and thus exempt from the draft. So reading the Walsh transcript they hit those topics again and again. They asserted they did indeed have a 'creed', a set of beliefs, which their ministers (which includes all witnesses, since 'all JWs are ministers') had to adhere to or else they would be removed. I don't think it is a coincidence that the disfellowshipping practice includes non-belief and started in '52. Their legal posturing resulted in some really outrageous statements in the transcript.
