It is not possible fully to understand what it means to be human without having some understanding of God. At least we have an experiential understanding of what it means to be a person, but God, for the vast majority, is a matter of concepts and those concepts light years from the reality. ‘God may be loved but not thought,’ the Cloud of Unknowing says. So, it is possible to speak with authority only of one’s own experience. This is why the teaching of Jesus is so important. He spoke of what he knew. We too can only speak of what we know but, unlike Jesus, this does not include God.
