“First, consider, That sin is never a, whit the less filthy, vile, and abominable, by its being coloured and painted with virtues colours. A poisonous pill is never a whit the less poisonous because it is gilded over with gold; nor a wolf is never a whit the less a wolf because he hath put on a sheep’s skin; nor the devil is never a whit the less a devil because he appears sometimes like an angel of light. So neither is sin any whit the less filthy and abominable by its being painted over with virtue’s colours.” —Thomas Brooks, Precious Remedies against Satan’s Devices
