26 Of this healing we, who are set over others, are the ministers and fellow-labourers; for whom it is a great thing to recognise and heal their own passions and sicknesses: or rather, not really a great thing, only the viciousness of most of those who belong to this order has made me say so: but a much greater thing is the power to heal and skilfully cleanse those of others, to the advantage both of those who are in want of healing and of those whose charge it is to heal.
