FLESH - (1) In New Testament usage, flesh refers to fallen human nature, which, through its ties to the world and mortality, struggles against spiritual growth and leads one into sin. Christians are called to subdue the lusts of the flesh so that they may grow in union with Christ (Rom. 8:4-9; Gal. 5:16-24). (2) In Christology, flesh refers to the sinless human nature of Christ, or the Body of Christ. In liturgical usage, there is reference to the flesh of Christ in the Eucharist.
