Incorruptible (861) (aphtharsia from a = not + phthartós = corruptible from the verb phtheíro = to corrupt, shrivel, wither, spoil by any process, ruin , deprave, defile, destroy) is a state of not being subject to decay or death - immortality, incorruptibility (state of being free from physical decay), perpetuity. Aphtharsia defines the state of not being subject to decay, dissolution or interruption. It speaks of an unending existence, of that which is not capable of corruption. Aphtharsia indicates immunity to the decay that infects all of creation. The idea is conveyed in our English phrase with an undying love. MacArthur comments that this love incorruptible is... the love that belongs to true believers; so Paul is really identifying the ones who will receive grace as only those whose love is not temporary and thus untrue but permanent and thus genuine! (MacArthur, J: Ephesians. Chicago: Moody Press) The Latin Vulgate translates aphtharsia as incorruptio. Vine writes that aphtharsia is used (a) of the resurrection body, 1Cor 15:42, 50, 53, 54; (b) of a condition associated with glory and honour and life, including perhaps a moral significance, Ro 2:7; 2 Ti 1:10; this is wrongly translated “immortality” in the AV; (c) of love to Christ, that which is sincere and undiminishing, Eph 6:24 (Vine, W E: Vine's Complete Expository Dictionary of Old and New Testament Words. 1996. Nelson) Freiberg says that aphtharsia in this verse... has three possible alternatives: (1) as qualifying love unceasing, undying; (2) as qualifying grace with incorruptibility, eternally; (3) as qualifying Christ and Christians in immortal life (Friberg, T., Friberg, B., & Miller, N. F. Analytical Lexicon of the Greek New Testament. Baker's Greek New Testament library. Baker Academic) Aphtharsia is found only in the NT and is used 7 times... Romans 2:7 (note) to those who by perseverance in doing good seek for glory and honor and immortality, eternal life; 1 Corinthians 15:42 So also is the resurrection of the dead. It is sown a perishable body, it is raised an imperishable body...50 Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable...53 For this perishable must put on the imperishable, and this mortal must put on immortality...54 But when this perishable will have put on the imperishable, and this mortal will have put on immortality, then will come about the saying that is written, "Death is swallowed up in victory. (Comment: The resurrection body has undergone a complete change as compared with the body of flesh like the plant from the seed. It is related to it, but it is a different body of glory. Aphtharsia refers to the incapacity of the new resurrection body to deteriorate or decay. This is a quality, however, that our present bodies do not have but will have in the resurrection.) Ephesians 6:24 Grace be with all those who love our Lord Jesus Christ with a love incorruptible. 2 Timothy 1:10 (note) but now has been revealed by the appearing of our Savior Christ Jesus, who abolished death, and brought life and immortality to light through the gospel Blaikie writes that... The expression is peculiar—love the Lord Jesus Christ in incorruptible. The word denotes, especially in Paul’s usage, what is unfading and permanent. The love that marks genuine Christians is not a passing gleam, like the morning cloud and the early dew, but an abiding emotion. Nowhere can we have a more vivid idea of this incorruptible love than in the closing verses of Ro 8, “I am persuaded that neither death nor life,” etc. (The Pulpit Commentary: New Testament; Old Testament; Ages Software)
