September Testament (1522)

On September 21, 1522, Martin Luther (1483–1546), age 36, released his German New Testament, soon known as the “September Testament.” It was a landmark in the church’s recovery of Scripture as the living voice of God for all His people. By placing the apostolic witness into common speech, Luther helped ordinary believers hear Christ’s words without dependence on clerical gatekeepers, and he pressed the conviction that the gospel is received by faith, not earned by works.

Wartburg Castle and the “Hidden Monk”

After the Diet of Worms (1521), where Luther refused to recant unless convinced by Scripture, he was taken into protective custody and hidden at Wartburg Castle near Eisenach. Disguised as “Junker Jörg” (Knight George), he lived in isolation yet labored intensely. The Wartburg became a place of providential shelter: a fortress not only of stone but of conscience, where courage was expressed through patient study, prayer, and obedience to God above fear of man.

Translation from the Greek Text

Working rapidly from the Greek New Testament, Luther aimed for clarity and faithfulness, using vivid German that could be read aloud in homes and churches. His approach reflected the belief that God intends His Word to be understood and treasured. “Your word is a lamp to my feet and a light to my path.” (Psalm 119:105). The September Testament also encouraged pastors to preach the text itself, forming congregations by Scripture rather than by custom alone.

Spiritual Significance and Lasting Fruit

The September Testament strengthened families and congregations to read, pray, and test teaching by the Word. It cultivated humility before God, renewed confidence in Christ’s saving work, and stirred moral courage to stand for truth. “For I am not ashamed of the gospel, because it is the power of God for salvation to everyone who believes.” (Romans 1:16). Luther’s full German Bible would follow in 1534, but the 1522 New Testament opened a door for widespread Scripture engagement that could not be shut.
