The clergyman was student of love, of the philosophy of love and the love-nexus world we evolved for, that we were created for.
In the love-nexus world the clergyman, or woman, was a pillar of the community, part of the emotional buffer system that kept people healthy and happy.
The clergyman was an expert in seeing the real person, seeing if they were taking the paths of emotional indifference or the paths of love. The teachings given spoke of love as the supreme first principle, of the right philosophy being the all important signpost. Thus instead of giving instructions he taught folk how to navigate. A flock will always need defence and shepherding, but a pack of "good wolves" who can keep evil at bay by themselves is strong. After all, if they need teaching all their lives, are they being taught anything at all?
To arrive at sustainability for creation the clergyman and woman's role in teaching how to love the world was essential. What God has given, man should cherish and protect.
