In seminary the class relating to preaching forms and techniques is called, "Homilectics." The name comes from the Greek, homiletikos, which means "to assemble together." A sermon is an assembly of ideas about God.
One of my classmates was an attorney, and when he preached it was like hearing someone read a legal contract. My sermons were criticized for not being "touchy, feely." I was told that I needed to be more dramatic. That was almost 20 years ago, so I will let you be the judge of my evolution......or decay!
A preacher should remember that the congregation does not have the benefit of reading the sermon while it is being preached. I suppose a sermon could be presented in a Powerpoint format, but that really seems more educational, than proclamational.
At St. James the Less our mission is to be an Episcopal presence in the community, pursuing the understanding of God’s grace while seeking the reconciliation of all people to each other and to unity with God.
“Holy Saturday seems to be fitting for the nature of our human life: We are still awaiting Easter; we are not yet standing in the full light, but walking toward it full of trust.” -Pope Benedict XVI
