A good Christian makes gospel piety and moral equity kiss each other. Herein some discover their hypocrisy: they will obey God in some things which are more facile, and may raise their repute; but other things they leave undone.The Ten Commandments, 2
A modest dress is a very good thing, if it be the genuine indication of a humble heart, and is to instruct; but it is a bad thing if it be the hypocritical disguise of a proud ambitious heart, and is to deceive. Let men be really as good as they seem to be, but not seem to be better than really they are.Matthew Henry's Commentary
