Robert Waznak, a preacher and for the past twenty-five years a popular teacher of preachers, believes that before we consider how to preach a homily we need to explore what the homily is. That is why An Introduction to the Homily is not just another "how to" book, but a work that leads to a practical understanding of what the Sunday homily is supposed to do. Based on theological and historical foundations, this work provides sound theory for homilists striving to improve their preaching.
