1 Corinthians 8:1

Now as touching things offered unto idols, we know that we all have knowledge. Knowledge puffeth up, but charity edifieth (KJV)

Then: A study outline of I Corinthians by Daniel B. Wallace places chapters seven through fourteen under a heading called "Difficulties in the Church." I Corin 8:1 returns to the problem of pride derived from knowledge. David Guzik notes that both knowledge and love grows, but compares the growth of bubbles as a matter of "swelling" as opposed to the careful, planned growth of buildings. All the commentators talk about knowledge. Some one of them has surely placed Knowledge, rather than money, as being the root of all evil. That would be reasonable since in The Garden, Evil tempts Eve to know all things. For Paul to use the misuse of knowledge as a continual teaching point is both logical and psychological.

Now: Knowledge still makes men proud - whether collectively or individually. Knowedge is useful and necessary in life, but when prized for its own sake, and without being based in love, it can cause interpersonal problems which last a lifetime. Men do not change. They need to discern self-instances of pride of knowledge.
