Studies on Erastus, the Corinthian oikonomos (Rom 16.23), continue to dispute the fundamental make up of his identity, including his administrative rank, socio-economic standing, even his status as a believer. Ultimately seeking to defend the view that Erastus was a Christian who served as a Corinthian municipal quaestor, this article responds separately to two recent essays, replying initially to Weiss' charge that Corinth did not have the municipal quaestorship, then critiquing Friesen's claim that Erastus was an unbelieving public slave.
