CIC 1034 Jesus often speaks of “Gehenna” of “the unquenchable fire” reserved for those who to the end of their lives refuse to believe and be converted, where both soul and body can be lost.1 Jesus solemnly proclaims that he “will send his angels, and they will gather. .. all evil doers, and throw them into the furnace of fire,”2 and that he will pronounce the condemnation: “Depart from me, you cursed, into the eternal fire!”3
