“Now, since these promises of God are words of holiness, truth, righteousness, liberty, and peace, and are full of universal goodness, the soul, which cleaves to them with a firm faith, is so united to them, nay, thoroughly absorbed by them, that it not only partakes in, but is penetrated and saturated by, all their virtues. For if the touch of Christ was healing, how much more does that most tender spiritual touch, nay, absorption of the word, communicate to the soul all that belongs to the word! In this way therefore the soul, through faith alone, without works, is from the word of God justified, sanctified, endued with truth, peace, and liberty, and filled full with every good thing, and is truly made the child of God, as it is said, "To them gave He power to become the sons of God, even to them that believe on His name" (John i. 12).”
Martin Luther changed the course of Western civilization by initiating the Protestant Reformation. As a priest and theology professor, he confronted indulgence salesmen with his 95 Theses in 1517. Luther strongly disputed their claim that freedom from God's punishment of sin could be purchased with money. 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 meeting in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the emperor.
Luther taught that salvation is a free gift of God and received only by grace through faith in Jesus as redeemer from sin, not from good works. His theology challenged the authority of the pope of the Roman Catholic Church by teaching that the Bible is the only source of divinely revealed knowledge and opposed sacerdotalism by considering all baptized Christians to be a holy priesthood.
His translation of the Bible into the language of the people (instead of Latin) made it more accessible, causing a tremendous impact on the church and on German culture. It fostered the development of a standard version of the German language, added several principles to the art of translation, and influenced the translation into English of the King James Bible. His hymns inspired the development of singing in churches. His marriage to Katharina von Bora set a model for the practice of clerical marriage, allowing Protestant priests to marry.
