They [rulers] must act like a good physician who, when gangrene has set in proceeds without mercy to cut, saw, and burn flesh, veins, bone, and marrow. Such a procedure must also be followed in this instance. Burn down their synagogues, forbid all that I enumerated earlier, force them to work, and deal harshly with them, as Moses did... If this does not help we must drive them out like mad dogs.
Martin LutherAs is the business of tailors to make clothes and cobblers to make shoes, so it is the business of Christians to pray.
Martin LutherWhat is it to serve God and to do His will? Nothing else than to show mercy to our neighbor. For it is our own neighbor who needs our service; God in heaven needs it not.
Martin LutherEvery week I preach justification by faith to my people, because every week they forget it.
Martin Luther
