"Do not lose your temper with those who sin. Do not have a passion for noticing every sin in your neighbor and judging it, as we usually do. Everyone will give an answer for himself before God. Especially, do not look with evil intention on the sins of those older than you, with whom you have no business. But correct your own sins, your own heart."

To judge sins is the business of one who is sinless, but who is sinless except God? Who ever thinks about the multitude of his own sins in his heart never wants to make the sins of others a topic of conversation. To judge a man who has gone astray is a sign of pride, and God resists the proud. On the other hand, one who every hour prepares himself to give answer for his own sins will not quickly lift up his head to examine the mistakes of others.
