 The stance adopted by Campanella in relation to universal monarchy is directly linked to the prophetic ideal of re-uniting humanity in a “single fold under one shepherd.” The central text for this topic is Monarchia del Messia (Monarchy of the Messiah). The original unity of king and priest, which derives from the divine unity, permits human beings, after the multiplicity of sects introduced by the devil and fomented by ambition and ignorance, to return to a single priestly law, under which the entire human race can come together, transcending divisions and conflicts. According to Campanella, Adam and Hermes Trismegistus were simultaneously kings, priests and wise men. Uniting kingship and priesthood in the same person is extremely advantageous and auspicious, for the people will more willingly obey those whom they believe have their authority from God; and their laws will be more respected and observed, whether in public or in the inner sanctum of the human heart. The epoch in which a king-priest will reign is described by Campanella as a golden age, in which there will be an end to the evils that afflict humanity: wars will no longer have any reason to exist; famine and scarcity will cease because the barrenness of certain countries will be corrected and supplemented by the abundance of foodstuffs produced in other countries; plagues will disappear because it will be possible to transfer people to salubrious lands free from contagion; finally, there will be a wondrous flourishing of all forms of knowledge thanks to exchanges of information and to communication, bringing great benefits to humanity (Monarchia del Messia, pp. 62–63). The division and the separation of human beings are always the devil’s work; envious of the good that comes from unity, he induces people to forget that they are all children of the same God and of the same father, Adam, and therefore siblings.
