I suppose you are right that I did not publish a
consideration that the avaricious Judas shared an 'ousias'
with the personal Devil, if I understand you properly that
you intend 'substance' by 'ousias' and not "property." But
I personally do not regard this as likely. I am aware of
the link some authorities make with John 13:2. But I think
Paul Dixon's response is more reasonable (to me anyway).
