Few issues were more hotly contested by early modern theologians than the extent of human liberty and its implications for both religion and society. In the Protestant world, the sixteenth century saw increasingly strident statements of mankind's bondage to sin and the importance of God's eternal decree of predestination, but the concept of human moral responsibility still had its defenders. One influential proponent of human liberty was Faustus Socinus (1539–1604), the Italian scholar known most commonly today for his denial of the trinity. Yet the central theme of his theology was his insistence that Christian virtues must be carried out voluntarily; it was from this principle that his more heterodox ideas flowed. He made a sharp distinction between natural and voluntary action, and argued that the practice of Christianity must be an act of human will, not one to which men were drawn by nature. Separating Christianity from the natural order, Socinus argued that eternal life awaited those who chose to follow the law of Christ rather than the natural law. His argument challenged the Protestant commitment to the unity of natural and divine law and it opened up conceptual space for voluntary action outside the natural law. In this article, I shall sketch the Socinian position on human liberty and Christianity, and suggest how and why the Italian's ideas were developed by Protestants in the early seventeenth century. His readers included the eminent Dutch scholar Hugo [End Page 191] Grotius (1583–1645), and the exchange between Grotius and the Socinians reveals the concern on both sides to explain the relationship between human liberty, Christianity, and natural law.

Socinus' life, like his theology, began within the reform movement in Italy and ended among the marginalised anti-trinitarians in Poland. Born of a long line of Italian jurists, he shared both his family's legal interests and their critical approach to the Catholic Church. In his youth he had been a courtier in Florence but his increasingly critical attitude towards Catholicism—and the death of his patron Grand-Duke Cosimo I—resulted in his departure from Italy in 1574. After a period in Basel he found a home among the Polish Anabaptists at Rakow, a young and precarious community which he helped to sustain through his advice and through the tracts which he penned on their behalf.¹ During these years, he was also able to develop his own interpretation of Christianity, and to explain it in numerous works issuing from the community's press. Although his ideas generated a lively debate from the start, both in Poland and Germany, it was only after his death that they began to be absorbed into the mainstream of European intellectual discussions. Socinus' theological ideas had their attractions for some Protestant readers, but they became entangled with more political questions and their implications for civil life began to cause serious alarm. For this reason my focus will be upon the responses of Dutch and German readers, particularly Hugo Grotius and Johan Crell (1590–1633), both of whom addressed the civil as well as the theological aspects of Socinus' legacy. First, however, I shall draw out the salient points from Socinus' rich and complex theology, paying particular attention to his understanding of human liberty. Unlike his orthodox Protestant contemporaries, Socinus believed that liberty was the precondition for virtue.

Socinus shared with the broader Christian humanist tradition the belief that Christ demanded works as well as faith from his followers. Christians must follow the pattern of ethical living laid down by their master; like Erasmus before him, and like the Italian exiles he met in Basel, Socinus saw Christianity as a religion of action.² For this reason, he was determined to protect the liberty and capacity of each individual to act virtuously, and therefore to defend what he understood as human free will. It was, he felt, [End Page 192] a pressing task, for these qualities were being undermined by his contemporaries and particularly by those on the Protestant side. Most Protestants followed Luther's belief, expressed most forcefully in De Servo Arbitrio (1525...
