and the spirit of the world, but most busily the spirit of malice, of wrath, and of wickedness, for he is the foulest and the worst filth[297] of all. And it is full needful and speedful to know his quaintise, and not for to unknow his doleful deceits. For sometime he will, that wicked cursed wight, change his likeness in to an angel of light, that he may under colour of virtue do more dere;[298] but yet then, if we look more redely,[299] it is but seed of bitterness and of discord that that he sheweth, seem it never so holy nor never so fair at the first shewing. Full many he stirreth unto singular holiness passing the common statute and custom of their degree, as is fasting, sharp wearing, and many other devout observances and outward doings, in open reproving of other men's defaults, the which they have not of office for to do. All such and many other he stirreth them for to do, and all under colour of devotion and of charity; not for he is delighted in any deed of devotion and of charity, but for he loveth dissension and slander, the which is evermore caused by such unseemly singularities; for where so ever that any one or two are in any devout congregation, the which any one or two useth any such outward singularities, then in the sight of fools all the remenant are slandered by them; but, in the sight of the wise man, they slander themselves. But for because that fools are more than wise men, therefore for favour of fools such singular doers ween that they be wise, when (if it were wisely determined) they and all their fautors[300] should be seen apert fools, and darts shot of the devil, to slay true simple souls under colour of holiness and charity. And thus many deceits can the fiend bring in on this manner.
