Tolerance in religion, it is well known, so unanimously admitted (at least verbally) even by theologians in the present century, was seldom considered as practicable, much less as a matter of right, during the period of the Reformation. The difference in this respect between the Catholics and Protestants was only in degree, and in degree there was much less difference than we are apt to believe. Persecution is the deadly original sin of the reformed churches; that which cools every honest man's zeal for their cause, in proportion as his reading becomes more extensive. The Lutheran princes and cities in Germany constantly refused to tolerate the use of the mass as an idolatrous service;[133] and this name of idolatry, though adopted in retaliation for that of heresy, answered the same end as the other, of exciting animosity and uncharitableness. The Roman worship was equally proscribed in England. Many persons were sent to prison for hearing mass and similar offences.[134] The Princess Mary supplicated in vain to have the exercise of her own religion at home; and Charles V. several times interceded in her behalf; but though Cranmer and Ridley, as well as the council, would have consented to this indulgence, the young king, whose education had unhappily infused a good deal of bigotry into his mind, could not be prevailed upon to connive at such idolatry.[135] Yet in one memorable instance he had shown a milder spirit, struggling against Cranmer to save a fanatical woman from the punishment of heresy. This is a stain upon Cranmer's memory which nothing but his own death could have lightened. In men hardly escaped from a similar peril, in men who had nothing to plead but the right of private judgment, in men who had defied the prescriptive authority of past ages and of established power, the crime of persecution assumes a far deeper hue, and is capable of far less extenuation, than in a Roman inquisitor. Thus the death of Servetus has weighed down the name and memory of Calvin. And though Cranmer was incapable of the rancorous malignity of the Genevan lawgiver, yet I regret to say that there is a peculiar circumstance of aggravation in his pursuing to death this woman, Joan Boucher, and a Dutchman that had been convicted of Arianism. It is said that he had been accessary in the preceding reign to the condemnation of Lambert, and perhaps some others, for opinions concerning the Lord's supper which he had himself afterwards embraced.[136] Such an evidence of the fallibility of human judgment, such an example that persecutions for heresy, how conscientiously soever managed, are liable to end in shedding the blood of those who maintain truth, should have taught him, above all men, a scrupulous repugnance to carry into effect those sanguinary laws. Compared with these executions for heresy, the imprisonment and deprivation of Gardiner and Bonner appear but measures of ordinary severity towards political adversaries under the pretext of religion;
