And the serpent said unto the woman, You shall not surely die:
All Commentaries on Genesis 3:4 Go To Genesis 3
Augustine of Hippo
AD 430
But it is most truly said … “Pride is the beginning of all sin,” for it was this sin that overthrew the devil, from whom arose the origin of sin and who, through subsequent envy, overturned the man who was standing in the righteousness from which he had fallen. For the serpent, seeking a way to enter, clearly sought the door of pride, when he declared, “You shall be as gods.” That is why it is written, “Pride is the beginning of all sin,” and “The beginning of the pride of man is to fall away from God.”
