What is prophetic preaching? Zach Mills, one of my collegues in the Modern Homiletics Theory course, summarized prophetic preaching as:

[P]reaching that creatively speaks-on behalf of others-of the injustices and inadequacies of the present and the hopeful possibilities of the future.

While studying for a class in Modern Homiletic Theory I came across these two important terms. The terms of interest to me now are the comparison between Kerygma and Didache in preaching. Often didache is seen as the “ethical instruction” in preaching. Kerygma’s purpose is seen as making new converts. Here we see a difference in purpose. Didache is for the converts and Kerygma is for the outsiders.
