Clement of Rome: First Epistle to the Corinthians

In the first three chapters of the epistle, the author, actually anonymous, condemns the sedition present in the church, which he attributes to a few selfish men. This criticism is strengthened as the author remembers how in the past his readers had been a model of Christian faith, their fall being attributed to pride.

Already in the first three chapters the writer's mastery of the Old Testament stands out, especially in the way that the OT flows into his natural style. Included is also a reference to the apocryphal Wisdom of Solomon [which would have been part of the Greek OT that he read.]
