Richard Hays identifies three ways a work can be deemed a classic in his Forward to Victor Paul Furnish’s Theology and Ethics in Paul. (Hays’ examples listed)

1. Comprehensive marshaling of data – they gather up what is known about a subject in an all-inclusive way (e.g. Martin Hengel’s Judaism and Hellenism)

2. Provocative, paradigm changing thesis – often highly controversial and generate ongoing debate within the discipline for many years after their publication ( e.g. E.P. Sanders’ Paul and Palestinian Judaism)

3. Consensus forming – concise but sagacious study that enters a confused, amorphous area of inquiry and articulates balanced synthetic judgments that promote the formation of a new consensus (e.g. Victor Paul Furnish’s Theology and Ethics in Paul)

Obviously Hays already identified several, but what other books are ‘classics’ within Pauline Studies? Why are they a classic?
