We are each one of us sharers in the priestly office of Jesus Christ through  incorporation into the Body of Christ through our Baptism and Confirmation. How we exercise that priesthood may perhaps be determined by our circumstances and lifestyle. As Paul suggested, some by teaching in schools or pulpit or College, some by our community concern as carers, social workers, visitors of the sick and housebound, some by our capacity for political action as community leaders,etc, etc. Priestliness should not be manifested by our 'religious persona', but rather by our love and service of our fellow human beings. 'Professional' clergy should be anathema to the Ecclesia. Leaders should emerge from our local communities by their capacity for goodness, gentleness and capacity for service and wisdom and their drawing of all into unity.The very notion of 'hierarchy' is nowhere to be found in the example and teaching of Jesus.
