This will usually involve describing, analysing and evaluating two contrasting scholarly approaches to the issue, then giving your own overall evaluation (what do you think, and what are your reasons?). When considering the issue, be specific about which biblical verses the argument(s) turns on. Make sure you have considered the major scholars in any area (for example, if you talk about the beginning of the new perspective on Paul you must at least refer to EP Sanders). Make sure at least part of the debate includes some aspect of Galatians (though it can range wider).
Reflection integrating your evaluation and your context
Now return to the specific issue/incident of your context - how does your evaluation of the Pauline issue impact on your context? What might you do or think differently in future? What are the implications?
