The passages the Scriptorium holds on screen, word for word from a public-domain translation. Written in German.
“Unless I am refuted and convicted by testimonies of the Scriptures or by clear arguments (since I believe neither the Pope nor the Councils alone; it being evident that they have often erred and contradicted themselves), I am conquered by the Holy Scriptures quoted by me, and my conscience is bound in the word of God.”
Luther before the Diet of Worms, 18 April 1521, in Schaff, History of the Christian Church VII §54 (1888), public domain. (trimmed quote)
“While Eck looked to the fathers, Luther went back to the grandfathers; he ascended from the stream of church history to the fountain of God’s Word.”
Schaff, History of the Christian Church VII §37 (1888), public domain.
“…the latter furnished the text from which, with the aid of Jerome’s Vulgate, the translations of Luther and Tyndale were made.”
Of Erasmus’ Greek Testament, in Schaff, History of the Christian Church VII, on the Bible in the vernacular (1888), public domain.
Notes
The September Testament was done in eleven weeks in hiding at the Wartburg. The full Bible took twelve more years and a room full of arguing — Melanchthon for the Greek, Aurogallus for the Hebrew, a standing committee over single words.
Luther’s rule was that you do not ask the Latin how to say it. You ask the mother in the house, the children in the street, the man at the market, and then you write down how they talk.
“Back to the grandfathers” is Schaff’s line for what happened at Leipzig, and it is the whole method: past the fathers, past the councils, to the fountain.
