“Thus the use which someone employed at a teacher makes of his reason in the presence of his congregation is purely private, since a congregation, however large it is, is never any more than a domestic gathering. In view of this, he is not and cannot be free as a priest, since he is acting on a commission imposed from outside.”

Words I can agree with, for with most jobs that you are being paid on a salary would not let you do what you please, of course within reasonable confines of the job description. In particular being say a public high school teacher in the state of New York for history. The state puts forth regents so that you have to make a curriculum to follow. With that comes the fact that you can’t just preach religion because of separation of church and state. the public school system being a part of the state.
