Who Is Fr. Juan de Mariana, S.J.
In his 1609 treatise, De monetae mutatione, Fr. Mariana, S.J. condemned the king’s debasement of the currency to pay off debts, calling it a form of "disguised robbery" that violated citizens' private property rights. He championed a stable currency, arguing that the foundations of an economy must not be altered. Fr. Mariana's principled stand for sound money and property rights four centuries ago echoes the core tenets of Bitcoin today.
