Luke operates within the framework of society as it existed at his time and so acknowledges the place of tax collectors and the military. They are warned against abusing their positions, against exploitation. There is a nexus between exploitation and people needing food and clothing, even if Luke does little more than juxtapose them. It may be that Luke is being a little tame here, accepting the role of the taxation system and the military of his time. However we may assess that, as a historian and theologian he has worked to reconstruct an application of the future vision of the kingdom to his present reality, setting an example for us to follow.
Personnel becomes important.
Jesus will take this role. Luke treats the material fairly conservatively. He might have smoothed out the difficulty that Jesus did not come waving a winnowing fork or brandishing fire. Instead he allows the predictions to stand. Luke worked creatively and in doing so stood in a living tradition which was life giving.
