This paper explores various issues pertaining to the exegesis of Greek conditional clauses, using as a case study the pair of conditional statements found in Galatians 1,8-9. These conditional curse formulations are broadly similar with reference to content, whilst also showing significant differences, notably in terms of mood. These conditional statements are firstly examined from syntactic and semantic perspectives. Their function in the discourse is then analysed with reference to Speech Act Theory. An integrative approach to exegesis of conditional clauses is advocated.
