This volume argues that the historical Jesus understood his mission, ministry, or vocation (or whatever we want to call it) in messianic categories. Jesus understood himself to be designated by God as the Messiah of Israel. There are many bricks used to construct this argument, and I recognize that while the foundations for the conclusion seem strong, some of the walls are stronger than others. As for which ones are the strongest or which less persuasive—that will be for others to decide.
