Seventeenth-century Genevan theologian François Turrettini (1623–87), a major exponent of the Reformed tradition, here sets out the understanding of the threefold ministry of Christ:
This mediatorial office of Christ is distributed among three functions, which are individual parts of it: the prophetic, priestly, and kingly. […] The threefold misery of humanity resulting from sin (that is, ignorance, guilt, and the 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 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.
