Here’s another little gem from Lenker’s introduction in Luther’s Genesis, a quotation from Luther on having too many books.
“The aggregation of large libraries tends to direct men’s thoughts from the one great book, the Bible, which ought, day and night, to be in every man’s hand. My object, my hope, in translating the Scriptures, was to check the so prevalent production of new works, and so to direct men’s study and thoughts more closely to the divine Word. Never will the writings of mortal man in any respect equal the sentences inspired by God. We must yield the place of honor to the prophets and apostles, keeping ourselves prostrate at their feet as we listen to their teaching. I would not have those who read my books, in these stormy times, devote one moment to them which they would otherwise have consecrated to the Bible.” (Martin Luther, Table Talk)
