The mission of the Jews?
We are priests.
As priests, we have a special mission.
There is a difference between a priest and a pastor.
A pastor is a person who has to be a teacher, a leader.
And contrary to what many people may say, I don’t think that being a light unto the nations means that we are the teachers of the world.
In any case, the world doesn’t like our teachings.
The role of the priest is, first of all, that the priest accepts a great number of special duties.
But as priests, we are, basically, a people, obsessed with God.
