Purity is the Essence of God and Gods nature is impeccable.<quoted text>
There is no proper word for religion in Hebrew. The closest we have is "the law". Religion, the concept, came later, from Greek philosophy.
The earlier musing was regarding Bufords use of the word purity. My understanding was that he was offering a Christian definition
"Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world." (NIV)
The Jewish religion does not share that concept of purity. Observing the law is a way to effectuate a sacred bond and not to effectuate purity, and it is linked to performing wordly activities, not in avoiding them.
Secondly, the goal to perform such activities is not to expunge sin, as in the case on several Christian theologies, as Jews do not share the concept of original sin either.
That is the Christian view of God.
