It must not be this way among Christians. Those who have honest and pious hearts should highly esteem their ministers and preachers in all humility and love, for the sake of Christ and of His Word. They should regard them highly as a gift and jewel given by God, more precious than any temporal treasure or possession. Similarly, true and pious preachers will faithfully seek only the welfare and the salvation of all people. They will not impose any burden on them, either in their consciences or even outwardly in their temporal possessions and physical existence. Whoever despises them should know that he is not a Christian and that he has lost the treasure once more. Our preaching and admonition is for everyone who will accept it and agree with us. Whoever refuses to do so and yet uses the name of the Gospel or the pretense of Christian brotherhood to despise us and to trample us underfoot, against him we use the art of letting him keep the pretense but actually taking everything back, so that he has nothing left at all. We have the command to separate ourselves from such people. We do not enjoy doing it, and we would have preferred to have them stay with us. But since they refuse, we must let them go and not let them ruin our treasure or trample it underfoot.  (Luther’s Works, v. 21, pages 228).

The right preventive measure here would be to take the Gospel seriously and to pray God faithfully that He may send true and faithful laborers into His harvest (Matt. 9:38). Then no one would have to be afraid. From such preachers we would not get oppression or compulsion or damage to our body or soul, but support and help and every kind of benefit for everyone. This has been true of us. We may well boast before God and the world that we have not sought any dominion or advantage for ourselves, but have served the whole world with our body and life. We have not imposed a burden or damage on anyone, but have gladly helped him, even in a temporal way. And for all this we have suffered danger, violence, and persecution. Since they do not like us any more, may God grant that others follow us who treat them otherwise, who oppress, torment, and skin them. Then they will see what they had in us, and they will have to take it from men whom they would not look at now or hire as stableboys. All they deserve is to have such tyrants of whom they have to be afraid, as they had the pope. He was the sort of government they need. Our crazy princes have just started to learn this. What they have in mind is to be unrestrained and unafraid of the pope. They are beginning to protect the clergy, not for their sakes but to subordinate them to themselves and to make them live by their good pleasure. They are protecting these clergy in such a way that it would be better for them to join sides with us, whom they consider to be their enemies, than to let their feathers be picked by the princes in the name of protecting them. But this is how it should be and must be, and it serves them both right. (Luther’s Works, v. 21, pages 227).
