The offering of [the body] is called a spiritual sacrifice because it is freely sacrificed through the Spirit, the Christian being uninfluenced by the constrainst of the Low or the fear of hell.
Martin LutherThe first care of every Christian ought to be to lay aside all reliance on works, and strengthen his faith alone more and more, and by it grow in the knowledge, not of works, but of Christ Jesus, who has suffered and risen again for him.
Martin LutherThe Jews are the most miserable people on earth. They are plagued everywhere, and scattered about all countries, having no certain resting place. They sit as on a wheelbarrow, without a country, people or government... but they are rightly served, for seeing they refused have Christ and his gospel, instead of freedom they must have servitude.
Martin LutherOur most merciful Father, seeing us to be oppressed and overwhelmed with the curse of the law . . . sent his only Son into the world and laid upon him all the sins of all men, saying, 'You be Peter that denier, Paul that persecutor, blasphemer and cruel oppressor, David that adulterer, that sinner who ate the apple in Paradise, that thief who hung upon the cross, and briefly, you be the person who has committed the sins of all men. See therefore that you pay and satisfy for them.'
Martin Luther
