The immoral priest is not needed by anyone. Neither to people nor to God.

You will not believe. No one needs a priest. There is no need for any intermediary between the buyer and the seller. The intermediary does not care about both the goods and the goods sold - only to not lose their profits. When you buy from an intermediary, you will never be sure of the authenticity.
But people are lazy: they do not turn to the primary sources, but to the merchants. Do not believe? Go to the primary sources yourself. Not in vain, by the way, the shoppers were chased out of the temple.
