6. The greatest difficulty is, Whether any self-revenge be lawful or due; which is answered by what is said already; none such as disableth us for God's service is lawful. But true repentance is an anger or great displeasure with ourselves for sin, and a hatred of sin, and loathing of ourselves for it; and to judge, condemn, and afflict our own souls by a voluntary self-punishing, is but that exercise of justice on ourselves, which is fit for pardoned sinners that are not to be condemned by the Lord, and indeed the just exercise of repentance and displeasure against ourselves.[343] On which accounts of sober self-revenge we may cherish such degrees of godly sorrow, fasting, coarse clothing, (as sackcloth,) and denying ourselves the pleasures of this world, as shall not be hurtful but helpful to our duty. And if great and heinous sinners have of old on these terms, exceeded other men in their austerities, and self-afflictings, we cannot condemn them of superstition, unless we more particularly knew more cause for it. But popishly to think that self-afflicting without respect to such causes or necessities is a meritorious perfection, fit for others, is superstition indeed.[344] And to think, as many of the melancholy do, that self-murder is a lawful self-revenge, is a heinous sin, and leadeth to that which is more heinous and dangerous.

Quest. CI. Is it lawful to observe stated times of fasting imposed by others, without extraordinary occasions? And particularly Lent?
Answ. Remember that I here meddle not with the question, how far is it lawful for rulers to impose such fasts on others? save only to say, 1. That it is undoubtedly fit for kings to do it by precepts, and churches by consent, in extraordinary cases of defection, sin, or judgments.[345] 2. That it is undoubtedly sinful usurpation, for either pope or any pretended ecclesiastical, universal rulers, to impose such on the universal church (because there are no universal rulers). Or for a neighbour bishop by usurpation to impose it on a neighbour church. 3. And that it is sinful in all or many churches, to make by their agreements such things to be necessary to their union or communion with their neighbour churches, so that they will take all those for schismatics that differ from them in such indifferent things. But as to the using of such fasts (omitting the imposing) I say,
I. 1. That so great and extraordinary a duty as holy fasting, must not be turned into a mere formality or ceremony.[346]
2. No particular man must be so observant of a public, commanded, anniversary fast, as for it to neglect any duty commanded him by God which is inconsistent with it. As to rejoice or keep a thanksgiving in Lent, upon an extraordinary obliging cause; to keep the Lord's day in Lent, as a day of thanksgiving and rejoicing; to preserve our own health, &c. It is not lawful in obedience to man, to fast so much, or use such diet, as is like to destroy our lives or health; these being not so far put into the power of man; nor can man dispense with us as to the duty of self-preservation. If God himself require us not to offer him our lives and health needlessly, as an acceptable sacrifice, nor ever maketh self-destruction our duty, no nor any thing that is not for man's own good; then we are not to believe without very clear proof that either prince or prelates have more power than ever God doth use himself.
3. Such an anniversary fast as is meet for the remembrance of some great sin or judgment, if commanded, is to be kept, both for the reason of it, and for the authority of the commander. For, 1. It is not unlawful as anniversary. (For, (1.) It is not forbidden, and, (2.) There may be just occasion. Some arbitrarily keep an anniversary fast on the day of their nativity (as I have long done); and some on the day that they fell into some great sin; and some on the day of the death of a friend, or of some personal, domestic, or national calamity; and none of this is forbidden.) 2. And that which is not unlawful in itself, is not therefore unlawful to be done because it is commanded; seeing obedience to superiors is our duty and not our sin, unless in sinful things.
4. Whether it be lawful or meet to commemorate Christ's sufferings by anniversary fasts, is next to be considered.
