If there is anything in us, it is not our own; it is a gift of God. But if it is a gift of God, then it is entirely a debt one owes to love, that is, to the law of Christ. And if it is a debt owed to love, then I must serve others with it, not myself. Thus my learning is not my own; it belongs to the unlearned and is the debt I owe them...My wisdom belongs to the foolish, my power to the oppressed. Thus my wealth belongs to the poor, my righteousness to the sinners... It is with all these qualities that we must stand before God and intervene on behalf of those who do not have them, as though clothed with someone else's garment...But even before men we must, with the same love, render them service against their detractors and those who are violent toward them; for this is what Christ did for us.

Despite the disagreements on the Eucharist the Marburg Colloquy paved the way for the signing in 1530 of the Augsburg Confession and for the formation of the Schmalkaldic League the following year by leading Protestant nobles such as John of Saxony Philip of Hesse and George Margrave of Brandenburg-Ansbach. Luther rarely encountered Jews during his life but his attitudes reflected a theological and cultural tradition which saw Jews as a rejected people guilty of the murder of Christ and he lived within a local community that had expelled Jews some ninety years earlier. "
Luther next set about reversing or modifying the new church practices.

His translation of the Bible into the vernacular (instead of Latin) made it more accessible which had a tremendous impact on the church and on German culture. Those who identify with Luther's teachings are called Lutherans. His refusal to retract all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the Emperor.
