1 And I, brethren, could not speak to you as to spiritual people but as to carnal, as to babes in Christ. 2 I fed you with milk and not with solid food; for until now you were not able to receive it, and even now you are still not able; 3 for you are still carnal. For where there are envy, strife, and divisions among you, are you not carnal and behaving like mere men? 4 For when one says, “I am of Paul,” and another, “I am of Apollos,” are you not carnal? (1 Corinthians 3:1–4, NKJV)
Paul had just identified “spiritual” people as those who “receive the things of the Spirit of God” (i.e., the revelation of the gospel truth through the apostles, 1 Cor. 2:14-15, 10-13). Sadly, Paul could not speak to the Corinthian Christians as spiritual people because they had remained unspiritual – carnal (“consisting of flesh, fleshy”). Failing to grow spiritually after their conversion to Christ, they were still only able to digest the milk of the word (v. 1-2). Their failure to mature in Christ led them to be anti-spiritual – carnal (having the nature and traits of the flesh, the opposite of “spiritual” in 1 Cor. 2:15) (v. 3-4). Their carnality was exhibited through their envy, strife, and divisions. Identifying themselves with men instead of with the “word of the cross” proved their carnality (1 Cor. 1:18). We must grow to spiritual maturity by receiving God’s word and putting away every attitude and action that opposes the word the Spirit revealed (1 Pet. 2:1-2; Heb. 5:12-14; Rom. 8:5-8).
