I am sorry if my query has led the discussion from its central focus. You did seem to reflect a possible ignorance to this. It does appear that the DSS took the love of God to an extreme, but yet you seem to have missed it somewhere.
Jewish theology does have certain uniformities within it as well as variations.
The Theology of the DSS was seemingly Apocralyptic, messianic, and ritualistic. This was an expression of their love of God. But other groups are like this, and not just Jews. This is where we'll get answeres. These people in the DSS certainly loved their creator and expressed it in many ways.
