Answer:
Historically, communities are divided among the few (oligarchy, bourgeoisie who want to have power) and the many are people, people who have to live under a democratic system. It was said that the voice of the people was the voice of God, but it was in a theocentric era where everything revolved around God, today it is an anthropocentric era and man is the center of everything. Because of that, little by little, the importance of giving the word of God has ceased.
The ideal of democratic assemblies is that they pursue the public good. However, many times the public good is not just "public good" and derives in other goods a certain sector of society. It is demonstrated with economic policies that do well to a sector of society.
