What are the sociopolitical implications for the valorization of the quality of 'grace' by the elocutionists?

Perhaps, oratorical grace was most important at the beginning of the 18th century when the church decided to train the preachers in the art of elocution, because of the criticism received from boring sermons. Ministers mastered this art by first understanding the text, and then by reading it properly in order to impart its message on his hearers. Several writers dedicated much literature to forming, classifying, and clarifying oratorical grace through elocution.
The elocutionists studied the grace of oratorical action in order to express a superior mode of behavior compared to the spontaneous quality of common speech. Gilbert Austin wrote Chironomia, a book dedicated to the art of gesture. Austin believed that "genuine oratorical grace can only be the result of refined cultivation adorning a superhero understanding, or the rare git of nature to a pure and exalted mind, expressed by the actions of a distinguished person." Austin's elitist stance on grace suggested that only the best of human race a graceful. Austin placed value in the social demeanor of an orator and to always use pure pronunciation in order not to offend an educated audience. Austin claimed that an orator is judged by others according to the excellence of graceful discourse and gesture; however, Francois Delsarte believed that the grace in men is a derivative of the body of God's grace.
Delsarte's philosophy of artistic grace and beauty was dependent on the interconnection of the mind, body, and soul. The true dramatic artist could reproduce in himself and accurately show to others every variety of character and grade of excellence through perfective trashing in bodily freedom rational insight, and an imaginative consciousness. Delsarte believed that oratorical grace is achieved by transcending the limits of a private ego and exemplify the universal form of man.
The use of grace through elocution caught my interest, because that is still pertinent in oration today. Take President Obama, for example, I firmly believe that he would not have been elected if he didn't use graceful speaking in the numerous public appearances he made on the campaign trail. Grace is a quality of speech that is forever an important issue in the art of public speaking.
