There has been much investigation into the content of a possible unifying kerygma of the New Testament. This is the idea that there is a common form of proclamation across the New Testament writers. It cannot be presupposed that there is such a unifying kerygma unless a suitable methodology for determining or detecting it can be proposed and tested. During the twentieth century there was much analysis by many eminent scholars. The more familiar methodologies of these scholars require reconsideration and those that are less well-known need to be worked through, particularly that of Eugene Lemcio. Lemcio provides us with a classification system that allows the work of scholars to be systematically compared. Lemcio's attempt to put aside preconceptions concerning the content of the kerygma and instead seek to determine what the New Testament text itself shows the word, message or proclamation to be provides a possible way to overcome circular analysis or thinking concerning this matter. Considerable detailed attention is paid to Lemcio's proposal and a rigorous examination of his methodology and its outcomes is undertaken. This provides the possibility of using his process as the basis for constructing a methodology that is sufficiently robust to be used as an effective tool for determining the content of a unifying kerygma that may be contained within the New Testament.
