Concise Bible Dictionary:

1. σαρκικός, “belonging to the flesh:” applied to the fallen condition of man: to his wisdom (2 Cor. 1:1212For our rejoicing is this, the testimony of our conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God, we have had our conversation in the world, and more abundantly to you-ward. (2 Corinthians 1:12)); and to his lusts (1 Pet. 2:1111Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul; (1 Peter 2:11)). The same word is translated CARNAL. In Romans 7:1414For we know that the law is spiritual: but I am carnal, sold under sin. (Romans 7:14) it is “fleshly,” morally (the state of a new-born soul under bondage, doing the things he hates); in Romans 15:2727It hath pleased them verily; and their debtors they are. For if the Gentiles have been made partakers of their spiritual things, their duty is also to minister unto them in carnal things. (Romans 15:27) it is “fleshly” physically; and in some passages it is the fleshly or carnal condition of the Christian as led of the flesh. The word occurs in 1 Corinthians 3:1, 3-41And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. (1 Corinthians 3:1)
3For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men? 4For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal? (1 Corinthians 3:3‑4)
; 1 Corinthians 9:1111If we have sown unto you spiritual things, is it a great thing if we shall reap your carnal things? (1 Corinthians 9:11); 2 Corinthians 10:44(For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) (2 Corinthians 10:4) and Hebrews 7:1616Who is made, not after the law of a carnal commandment, but after the power of an endless life. (Hebrews 7:16). In most of these passages some MSS read σάρκινος, “fleshy.”
