It's very cool that my son is old enough to be a partner in dialogue! Knotwurth was responding to my post on philosopher Paul Ricoeur, Spoken Word, Sacred Text. He quite rightly saw that this video illustrates Ricoeur's point:
It is the function of preaching to reverse the relation from written to spoken. In that sense preaching is more fundamental to Hebrew and Christian tradition because of the nature of the text that has to be reconverted to word, in contrast with Scripture.
At one point, people are moved to applause — but tentatively, as if they're not sure it's an appropriate reaction. Later, they just let 'er rip. It isn't often that a congregation is transported by scripture like this!
