Sadness of the 'Emerging Church'

On Adrian Warnock's blog today is the sad report not only of Brian Mclaren's support for the views of Steve Chalke in regard to Penal Substitution, but also an example of Brians failure to honour Gods word by offering no answer to one of his 'flock' who asked "why did Jesus have to die".
Brians reply was basically "I don't know and neither did Jesus. The point wasn't understanding it; the point was doing what needed to be done." (This via Brians brother Peter)
I do not know what Church they are supposed to represent, but it is not the Church of Jesus Christ.
