The threefold misery of humanity resulting from sin (that is, ignorance, guilt, and oppression and bondage of sin) required this threefold office. Ignorance is healed through the prophetic office, guilt through the priestly, and the oppression and bondage of sin through the kingly. The prophetic light scatters the darkness of error; the merit of the priest removes the guilt and obtains reconciliation for us; the power of the king takes away the bondage of sin and death. The prophet shows God to us; the priest leads us to God; and the king joins us together with God, and glorifies us with him. The prophet illuminates the mind by the spirit of enlightenment; the priest soothes the heart and conscience by the spirit of consolation; the king subdues rebellious inclinations by the spirit of sanctification.
