For when the heart is evil, all its works are evil, no matter how splendid they are. [And here it is clear that God is speaking, because He judges their hearts.] 1 And this word aptly and clearly expresses the nature of hypocrisy, which is a righteous performance in the eyes of men on earth, but is evil in the heart. Such are all heretics, all pretenders who create an appearance in public to which their heart does not correspond.
- Martin Luther
