Pelagius — on 1Cor 3:12 (COMMENTARY ON THE FIRST EPISTLE TO THE CORINTHIANS 3)

“The house does not build itself; somebody has to put the walls up. This is the role of teachers in the church. The gold, silver, etc., represent six different types of hearers. Gold stands for good respondents, silver for better ones (because silver is stronger than gold) and precious stones for the best of all. Similarly, wood stands for bad people, hay for those who are worse and straw for the worst of all.”
