I think part of the problem is definition.
Is excitement and loud volume yelling? I am thinking of the preaching of men like JR de Witt or John Piper.
Or, are we thinking of fundamentalist shrieking?
I think Ken is right, that part of the problem is definition. I think that volume is important, namely (as Dabney put it) "we must so utter as to be heard," but to be careful to avoid shrill in one's tone.
Now, having had Dr. de Witt for all three semesters of systematics at RTS, it is my humble opinion that he preached systematic theology rather than simply going over his notes, for which I will always be grateful. I listened to Dr. de Witt preach in chapel many times, and there is no one whose preaching I would rather hear than his. I still chuckle with amusement and appreciation for his loathing of the word "share" ever having any place for what one does in the pulpit.
I offer this one anecdote about Dr. de Witt. I recall an occasion from seminary when Dr. R. C. Sproul was scheduled to speak in Grace Chapel on the Jackson campus of RTS (there were no other RTS campuses at the time). Well, there was an air of excitement on campus in anticipation of Dr. Sproul speaking in chapel. However, when the time for chapel was approaching that day, I noticed Dr. de Witt making his way to chapel with his robe folded over his arm, a tell-tale sign that circumstances had changed, for Dr. de Witt followed the same procedure each time he was to preach in chapel. One knew that to see Dr. de Witt with his robe in hand, he was slated to preach that day.
Well, when the student body gathered in chapel that day, sure enough, no Dr. Sproul. I forget what the providential hindrance was that prevented his arrival, but it was clear to all that he would not be the guest speaker for chapel. At the beginning of the chapel service, Dr. de Witt stood up, and uttered in words never to be forgotten by me - he said, "All of you who came to hear Dr. Sproul today may leave, and all who came to worship God may stay!" No one so much as twitched!
As for my personal preference, I'd rather hear Dr. de Witt preach any day of the week than Dr. Sproul, but then that is another matter.
