In "Doctrinal Discussion" Randy Bland writes:

Paul wrote his letter to the Colossians to refute some heretical teachings that had seeped into the Church. One of these heresies was that Jesus was not divine; He was just a good man who taught valuable lessons to follow. The heretics were trying to convince the Church that they still needed rules and secret knowledge to ensure that they would be saved. This heresy can still be found in some churches today, so Paul's majestic hymn to the supremacy of Christ is as important now as it was then.

Discussion: How do you see Jesus' authority being questioned today, even, at times, in the church?
