The Reformation brought about toleration neither by design nor directly, but as a by-product. None of the great reformers— Luther, Calvin, Zwingli—were tolerant of their opponents. In defence of his own position, Luther was first obliged to challenge papal authority, then to expound the right of the secular ruler to declare the religious policy of his state. That formula was accepted in the Augsburg peace of 1555 —cuius regio, eius religio (the ruler shall decide religion). Only catholicism or lutheranism were permitted choices and there was no provision for toleration. But in practice political considerations sometimes made rulers embrace toleration. Countries like Prussia, which were chronically short of labour, might find it imprudent to drive out subjects and might welcome refugees from less tolerant states: the Hohenzollerns who, as calvinists, were of a different faith from the vast majority of their lutheran subjects, might think twice before insisting on their formal rights. Augsburg even contained a slight measure of practical toleration in that, in a vastly divided Germany, subjects might move to a more friendly state.
Nevertheless, for decades the dream of a reunited Christendom dominated, either by force or by theological compromise. Force failed. The Emperor Charles V was unable to reconquer northern Europe in the 1550s and the Thirty Years War ended in 1648 with the religious boundaries largely unchanged. Well-meaning men arranged conferences and debates where rival theologians could agree on fundamentals and reach common ground. They failed at Marburg in 1529, at Worms and Regensburg in 1541, at Regensburg again in 1546. Even conferences to unite the protestants failed. James I summoned anglicans and puritans to Hampton Court in 1604 without success: Charles II called the Savoy Conference between anglicans and presbyterians in 1661. It failed. Under these dispiriting circumstances, the few voices calling for toleration were accorded increased attention. Could we not have, asked Milton, ‘a little generous prudence, a little forbearance of one another, and some grain of charity?’
In England there had been little need for a hunt after heretics until the late 14th cent., when Wyclif's teaching combined with social unrest to produce lollardy. The authorities responded with the act of 1401 De heretico comburendo—on the burning of heretics. In the 16th cent., Henry VIII executed catholics for treason, reformers for heresy; Mary burned reformers; Elizabeth executed catholic priests. anabaptists, regarded with peculiar horror, were hunted down by rulers in almost all countries. The seed-time for toleration in England was after the civil war, when sects multiplied and the victorious parliamentary army demanded from the presbyterians toleration for baptists, congregationalists, and independents. Cromwell lent his vast prestige to the cause of toleration, readmitting Jews to England after a gap of nearly four hundred years.
The Restoration in 1660 saw a lurch backwards, with Parliament passing severe legislation against catholics and dissenters. But, again, the exigencies of politics called for tactical behaviour and Charles II and James II both issued Declarations of Indulgence. In the crisis of 1688, when the dissenters held the balance between the anglicans and the king, they supported the revolution, and reaped the reward from William III in 1689 in the Toleration Act, which at least permitted freedom of worship. It was far from complete. Toleration did not apply to catholics, who faced a battery of penal laws, nor to anti-Trinitarians. In Scotland, episcopalians were persecuted as crypto-Jacobites. Even protestant dissenters did not have full civil rights and could neither sit in Parliament nor on corporations unless their consciences were flexible. But the narrow basis was gradually broadened, with concessions to the quakers over oath-taking and to the Scottish episcopalians over lay patronage. Underpinning the shift in policy was the start of a change in attitude. In his Letter on Toleration, published in 1689, Locke caught a new mood of calm reason: persecution created, not converts, but hypocrites, ‘for no man can, if he would, conform his faith to the dictates of another … All the life and power of true religion consists in the inward and full persuasion of the mind.’
There remained the problem of civil equality. No catholic and few dissenters could be MPs. But once the catholics had demonstrated their loyalty in the 1745 invasion, small concessions were made, and in Ireland catholics were given the vote in 1793. Though full emancipation for catholics was held up in 1801 by the refusal of George III to sanction it, it was granted in 1829. Dissenters were allowed into Parliament in 1828 and more concessions on tithes and on marriages followed. In 1858 Jews were allowed into Parliament. At length, in 1886, after the Bradlaugh case, even atheists were admitted to Westminster. From the beginning of the Reformation, it had taken a mere 350 years.
