John Locke’s Letter Concerning Toleration

I was doing some research when I stumbled on John Locke’s Letter Concerning Toleration (1689), and given the current controversy in the US about religion and politics I thought I might pass it on.

The background is that one of Locke’s friends asked for his opinion on the matter of religious toleration, and this was his personal reply. In summary, Locke thought that freedom of thought and toleration of other beliefs was integral to Christian life. However, this freedom and toleration should not be taken as a license to sin.

I find that–in the first part of his letter, at least–his own opinions closely match my own, but are much more eloquently stated. Here is the first section, with paragraph breaks added and minor edits for clarity:

Since you are pleased to inquire what are my thoughts about the mutual toleration of Christians in their different professions of religion, I must needs answer you freely that I esteem that toleration to be the chief characteristic mark of the true Church. For whatsoever some people boast of the antiquity of places and names, or of the pomp of their outward worship; others, of the reformation of their discipline; all, of the orthodoxy of their faith … these things … are much rather marks of men striving for power and empire over one another than of the Church of Christ. Let anyone have never so true a claim to all these things, yet if he be destitute of charity, meekness, and good-will in general towards all mankind, even to those that are not Christians, he is certainly yet short of being a true Christian himself …

The business of true religion … is not … to the erecting of an external pomp, nor to the obtaining of ecclesiastical dominion, nor to the exercising of compulsive force, but to the regulating of men’s lives, according to the rules of virtue and piety. Whosoever will list himself under the banner of Christ, must, in the first place and above all things, make war upon his own lusts and vices. It is in vain for any man to unsurp the name of Christian, without holiness of life, purity of manners, benignity and meekness of spirit. “Let everyone that nameth the name of Christ, depart from iniquity.” …

It would, indeed, be very hard for one that appears careless about his own salvation to persuade me that he were extremely concerned for mine. For it is impossible that those should sincerely and heartily apply themselves to make other people Christians, who have not really embraced the Christian religion in their own hearts. If the Gospel and the apostles may be credited, no man can be a Christian without charity and without that faith which works, not by force, but by love.

Now, I appeal to the consciences of those that persecute, torment, destroy, and kill other men upon pretence of religion, whether they do it out of friendship and kindness towards them or no? And I shall then indeed, and not until then, believe they do so, when I shall see those fiery zealots correcting, in the same manner, their friends and familiar acquaintance for the manifest sins they commit against the precepts of the Gospel; when I shall see them persecute with fire and sword the members of their own communion that are tainted with enormous vices and without amendment are in danger of eternal perdition; and when I shall see them thus express their love and desire of the salvation of their souls by the infliction of torments and exercise of all manner of cruelties. For if it be out of a principle of charity, as they pretend, and love to men’s souls that they deprive them of their estates, maim them with corporal punishments, starve and torment them in noisome prisons, and in the end even take away their lives — I say, if all this be done merely to make men Christians and procure their salvation, why then do they suffer whoredom, fraud, malice, and such-like enormities … to predominate so much and abound amongst their flocks and people? These, and such-like things, are certainly more contrary to the glory of God, to the purity of the Church, and to the salvation of souls …

Why, then, does this burning zeal for God, for the Church, and for the salvation of souls … pass by those moral vices and wickednesses, without any chastisement … ?

… adultery, fornication, uncleanliness, lasciviousness, idolatry, and such-like things, cannot be denied to be works of the flesh, concerning which the apostle has expressly declared that “they who do them shall not inherit the kingdom of God.” Whosoever, therefore, is sincerely solicitous about the kingdom of God and thinks it his duty to endeavour the enlargement of it amongst men, ought to apply himself with no less care and industry to the rooting out of these immoralities than to the extirpation of sects. But if anyone do otherwise, and whilst he is cruel and implacable towards those that differ from him in opinion, he be indulgent to such iniquities and immoralities as are unbecoming the name of a Christian, let such a one talk never so much of the Church, he plainly demonstrates by his actions that it is another kingdom he aims at and not the advancement of the kingdom of God.

That any man should think fit to cause another man — whose salvation he heartily desires — to expire in torments, and that even in an unconverted state, would, I confess, seem very strange to me, and I think, to any other also. But nobody, surely, will ever believe that such a carriage can proceed from charity, love, or goodwill. If anyone maintain that men ought to be compelled by fire and sword to profess certain doctrines, and conform to this or that exterior worship, without any regard had unto their morals; if anyone endeavour to convert those that are erroneous unto the faith, by forcing them to profess things that they do not believe and allowing them to practise things that the Gospel does not permit, it cannot be doubted indeed but such a one is desirous to have a numerous assembly joined in the same profession with himself; but that he principally intends by those means to compose a truly Christian Church is altogether incredible.

It is not, therefore, to be wondered at if those who do not really contend for the advancement of the true religion, and of the Church of Christ, make use of arms that do not belong to the Christian warfare. If, like the Captain of our salvation, they sincerely desired the good of souls, they would tread in the steps and follow the perfect example of that Prince of Peace, who sent out His soldiers to the subduing of nations, and gathering them into His Church, not armed with the sword, or other instruments of force, but prepared with the Gospel of peace and with the exemplary holiness of their conversation. This was His method. Though if infidels were to be converted by force, if those that are either blind or obstinate were to be drawn off from their errors by armed soldiers, we know very well that it was much more easy for Him to do it with armies of heavenly legions than for any son of the Church, how potent soever, with all his dragoons.

The toleration of those that differ from others in matters of religion is so agreeable to the Gospel of Jesus Christ, and to the genuine reason of mankind, that it seems monstrous for men to be so blind as not to perceive the necessity and advantage of it in so clear a light.

Locke goes on to spell out his own views on how the government should relate to religion. I do not agree completely with what he wrote in the sections that follow. Nevertheless, his overall argument is still interesting and may be of current value. His section on what the state can and cannot do for people is of particular interest, and speaks directly to the political situation in America today:

Will the magistrate provide by an express law that such a one shall not become poor or sick? Laws provide, as much as is possible, that the goods and health of subjects be not injured by the fraud and violence of others; they do not guard them from the negligence or ill-husbandry of the possessors themselves. No man can be forced to be rich or healthful whether he will or no. Nay, God Himself will not save men against their wills.
