Brōsis (βρῶσις) denotes either the act of eating or the food itself — often with more abstract or metaphorical weight than the concrete brōma. Its most significant theological use is in John 4:32 and 6:27, where Jesus speaks of "food" (brōsis) that the world cannot give and does not know about — referring to doing God's will and the heavenly bread of His body.
"Do not labor for the food (brōsis) that perishes, but for the food that endures to eternal life, which the Son of Man will give to you" (John 6:27) — this saying reorients all human striving. Physical sustenance is temporary; spiritual nourishment through Christ is eternal. Colossians 2:16 warns against being judged over food and drink — the reality belongs to Christ, not to regulations.
