— "I did not immediately consult with any human" (literally "flesh and blood") — is not heavily featured in JW proof-texts. It enters the discussion mostly through idiom analysis, where the Watchtower's reading of "flesh and blood" elsewhere (especially ) is treated as denying bodily resurrection.
is a clean idiom-case. Paul says he did not consult "flesh and blood" (sarki kai haimati) — meaning he did not seek out human authority or human advice. "Flesh and blood" here clearly means "mortal humans," not "physical substance" or "meat and fluid." Jesus uses the same idiom in — "flesh and blood did not reveal this to you, but my Father in heaven" — with the identical meaning: ordinary human sources. Paul uses it again in — "our struggle is not against flesh and blood, but against the governments" — where "flesh and blood" means human beings as contrasted with spirit beings. And uses the same phrase paired with "the perishable" to describe mortal human weakness. The Watchtower's move — using "flesh and blood cannot inherit the Kingdom of God" (1 Cor 15:50) to deny bodily resurrection — reads a biological claim out of a standard Semitic idiom. The four parallel uses (, , , ) settle the meaning: "flesh and blood" = mortal human. The resurrection body of is "flesh and bones" — real and physical, but no longer mortal.
