1 Corinthians 3:1-4
Paul here admonishes the Corinthians for being “carnal.” The word is the greek sarkikos, and means: pertaining to the flesh… by implication, unregenerate (from Strong’s).
This designation is the opposite of “spiritual”, and indicates that the flesh was winning in its conflict with the Spirit in their lives (cf. Galatians 5:17).
What was their sin? They were divided. Rather than expressing love for one another, and “endeavoring to keep the unity of the Spirit in the bond of peace” (Ephesians 4:3), they were “behaving like mere men.”
It is not godly to be a strife bearer and envious. To be so is antithetic to Christ’s cause. Those who are His must show their love to one another as brothers and sisters in Christ (1 Peter 2:22). One way this is done is to “all speak the same thing” and to be “perfectly joined together in the same mind and in the same judgment” (cf. 1:10).
