The Curse: the Serpent
After God determines the Man and Woman ate of the Tree based on the temptation of the Serpent, He curses them all. The Curse fits the crime.
The Serpent’s curse is fitting in two ways: 1) most Christians believe that the Serpent is Satan, who was cast from heaven for his pride in wanting to take God’s place. So Satan attempted to take the highest place and was cursed by being assigned the lowest place. 2) The Serpent sought to kill Man and Woman, but it will be the Serpent that dies.
Verse 3:15 is said to contain the first messianic prophecy: ‘I will put enmity between…your seed and (the woman’s seed),; he will crush your head and you will strike his heel.’ The prophecy is similar to the later notion that Death took Christ for three days (‘you will strike his heel’), but that Christ ultimately defeated Death for all-time (‘he will crush your head’). Christ was injured, but Death was destroyed. The serpent brought death to humanity, but the prophecy describes an battle in which the Woman’s Seed (Christ) is ultimately victorious over Death.
