This chapter weighs the evidence for sarcasm in Paul’s expression of astonishment (thaumazō hoti) in the opening of Galatians (1:6), which some scholars have considered an epistolary convention for expressing ‘ironic rebuke’. I then discuss whether the epithets that Paul uses to refer to the ‘pillar’ apostles in Gal 2:2, 6, and 9 can be classified as sarcastic and how their use serves Paul’s rhetorical aims across the autobiographical section of Galatians, before pushing back on a common misidentification of sarcasm in Gal 5:12.
