We do not then reject good works; nay, we embrace them and teach them in the highest degree. It is not on their own account that we condemn them, but on account of this impious addition to them and the perverse notion of seeking justification by them. These things cause them to be only good in outward show, but in reality not good, since by them men are deceived and deceive others, like ravening wolves in sheep's clothing.
- Martin Luther
