"What does this mean?--Answer. We should fear and love God that we may not deceitfully belie, betray, slander, or defame our neighbor, but defend him, [think and] speak well of him, and put the best construction on everything."

"Next, it extends very much further, if we are to apply it to spiritual jurisdiction or administration; here it is a common occurrence that every one bears false witness against his neighbor. For wherever there are godly preachers and Christians, they must bear the sentence before the world that they are called heretics, apostates, ye, seditious and desperately wicked miscreants. Besides, the Word of God must suffer in the most shameful and malicious manner, being persecuted, blasphemed, contradicted, perverted, and falsely cited and interpreted."

"All this has been said regarding secret sins. But where the sin is quite public so that the judge and everybody know it, you can without any sin avoid him and let him go, because he has brought himself into disgrace, and you may also publicly testify concerning him. For when a matter is public in the light of day, there can be no slandering or false judgment ore testifying; as, when we now reprove the Pope with his doctrine, which is publicly set forth in books and proclaimed in all the world. For where the sin is public, the reproof also must be public, that every one may learn to guard against it."

Because this is a public matter and out of my jurisdiction, I am sending a copy of this letter to Pres. Mueller."
