Book excerpt: The goal of this book is to demonstrate that sermons are "rhetorical" speeches by nature. The simplest argument is that it would be difficult to imagine a sermon without intent, and all international speeches are rhetorical by definition. This work focuses on the fact that rhetoric, as the intrinsic cohesive power of speech, is not a question of form, style or representation but a practical skill based on "common sense" that produces effective speech in the most optimal way possible.
