One of the highlights at Greenville is the Senior Sermon. Each M. Div. student in the last year must preach for chapel. Afterward, each of the professors examines the sermon in relation to his field.
For example:
Dr. Pipa comments about the logic and structure of the sermon.
Dr. Carrick comments about the delivery, time usage, rhetorical skill, etc.
Dr. Smith comments about the use of systematic theology.
Dr. Willborn comments about the use of church history and biblical theology.
Dr. Dyer or Shaw (NT/OT) comment about exegetical points in the passage.
The result is the non-seniors constantly being reminded how their studies influence their preaching. It is a great motivation for study, as well as exposure to fantastic preaching. The best thing is hearing a great senior sermon, and then hearing how it could be even better.
