Is Paul referencing Ecclesiastes in 1 Corinthians 15:32?

At the turn of the 20th century Paul Haupt wrote on Ecclesiastes:

The genuine portions of Ecclesiastes are Sadducean and Epicurean; Stoic doctrines are found almost exclusively in the Pharisaic interpolation.

The idea of Epicurean influence on it is also argued in Malkin, Epicurean Influence in the Books of Ecclesiastes and Job, Written in the Hellenistic Period (2009).

Personally I don’t think there’s enough there to argue directionality, but there is a case for similarity between the two (as well the beliefs of the Sadducees as represented in Josephus and the Epicureans).

Then in terms of 1 Cor 15, there’s Syzmik, The Corinthian Opponents of the Resurrection in 1 Cor 15:12 (2020):

1 Cor 15 contains terminological and ideological parallels to Epicureanism, especially, by way of opposition.

The picture in Corinth may be a bit more complicated than simply “it was Epicureans” (for example, see Klutz, Re-Reading 1 Corinthians after Rethinking ‘Gnosticism’ (2016)), but it’s probably a safe bet to identity Paul’s comments here as targeting Epicurean influenced attitudes, particularly given the anti-resurrection context amidst the capital of Greece and the parallel debate with the Epicureans in Acts.
