The author of the post is specifically talking about preaching on the Environment, but one can easily adapt the discussion to such issues as Racism, Classism, or other issues that might be a problem in your particular parish.
The next preaching pattern is David Buttrick’s “Plot’s and Moves” pattern for sermon construction. What is interesting about his methodology is that he conceives of the preaching task as preaching not to “individuals” neither to “groups of individuals”, but to a community.
The next pattern from Ronald Allen’s book Patterns for Preaching is Paul Scott Wilson’s approach described in his book The Four Pages of the Sermon The sermon under this structure is a manuscript with four distinct pages. Each page is a different approach to the materials.
Peter Mead over at Biblical Preaching has a series going on Preaching without notes that I referred to in this post. In his first post he described why preaching without notes is a valuable method.
In the second post which can be found here, Mead emphasizes the HOW. Mead’s method can be summed up in one word, “internalization.”
