Another aspect to Gavesi, is that he knows what a leader is suppose to be i.e not in the same position as the others.
Because IF he himself was not celibate, for example, how can he encourage or instruct others in the actual practice of celibacy etc
How can he who is drowning save another from drowning, so to speak?
There is a correlation with this sutta and MN 150: not honouring those who are virtuous part-time
In MN150 the Buddha is advising householders who they should respect.
