The consensus interpretation of 1 Corinthians 3.12–15 assumes that the building materials of 3.12 and the ‘work’ of 3.13–15 refer to the activity of the builders, usually understood as their preaching, teaching, or evangelism. This interpretation, however, leads to severe theological problems in 3.15. An alternative reading, suggested by Adolf Schlatter but largely ignored since, views the building materials and ‘work’ as human persons. This article bolsters Schlatter's reading with contextual, linguistic, theological, and patristic support. Four potential objections to this reading are then met.
