Epiphany shows the importance and origin of baptism: the spiritual significance and substance of physical realities. It also shows the nature of the Creator, His great humility and patience. It also shows how that as an adult, one is responsible before God and man, on earth and in heaven, for their own actions, which is why Christ was baptized as an adult.
