Johannes Reuchlin and the De Verbo Mirifico: The Word of Power
In 1510, the Holy Roman Emperor Maximilian I faced a question that had little to do with armies. A converted Jew named Johannes Pfefferkorn had persuaded him to order the confiscation and burning of Jewish books throughout the empire, and the emperor asked a few learned men whether this was wise.
One of them was a lawyer from the German town of Pforzheim, who knew Greek, Latin and Hebrew, and who answered that the books should be preserved. That scholar was Johannes Reuchlin. His reply began one of the great quarrels of the Renaissance, and the roots of his courage lay in a small book on a single name.
A Humanist Who Learned Hebrew
Reuchlin was born in Pforzheim in 1455. He studied in Paris, Basel, Orléans and Poitiers, and he learned Greek from some of the best teachers of his day. He became a lawyer and served the Count of Württemberg on diplomatic journeys to Italy.
There he met the circle of Marsilio Ficino and Giovanni Pico della Mirandola in Florence, scholars who believed that ancient wisdom was hidden in Plato, in Hermes and in the Jewish Kabbalah.
Pico's example set Reuchlin on a lifelong path. He sought out Jewish teachers and studied Hebrew at a time when few Christians in northern Europe could read it. He later wrote the first Hebrew grammar by a Christian in Germany, De rudimentis hebraicis (1506), which was a landmark in the history of the language.
The Wonder-Working Word
De verbo mirifico, "On the Wonder-Working Word," appeared in Basel in 1494. It is a dialogue among three characters, a pagan philosopher named Sidonius, a Jew called Baruchias and a Christian named Capnion, which is the Greek form of Reuchlin's own name, meaning "smoke." They discuss the power of words and the names of God.
The central argument concerns the Hebrew name of God, written with four letters, Yod, He, Vav, He, the Tetragrammaton, which Jews do not pronounce. Reuchlin claims that in the era of the Messiah, a letter, the Hebrew shin, was inserted into the middle of the name, making a five-letter name: Yod, He, Shin, Vav, He.
This is the pentagrammaton, and Reuchlin reads it as Yeshua, Jesus. For him it was proof that the Kabbalah, rightly understood, supports Christian belief. This is a Christian reading and would not be accepted in the Jewish tradition. It reflects the hope of Pico and his followers, the Christian Kabbalists, that Jewish mysticism and Christianity could be joined.
Letters and Power
Behind the argument lay an old idea, found in the Kabbalah and in some Neoplatonic writing, that sacred names are not just labels but carry a kind of power. Reuchlin did not offer a technique of magic, and the book contains no spells.
It is a work of Renaissance scholarship, full of citations from Plato, Pythagoras and the Church Fathers, and its interest in the "wonder-working" name is largely philosophical.
The same approach shaped his second Kabbalistic work, De arte cabalistica (1517), which he dedicated to Pope Leo X. It was widely read, and it helped introduce the Kabbalah to European scholars and later to writers such as Cornelius Agrippa.
The Battle of the Books
The quarrel with Pfefferkorn grew into a European affair. Reuchlin's opinion in 1510 argued that Jewish books, other than those that directly attacked Christianity, should not be destroyed. Pfefferkorn replied with pamphlets, and Reuchlin with his own defense, the Augenspiegel, "Eyeglass," in 1511. The theologians of Cologne, led by the Dominican Jacob van Hoogstraten, charged him with heresy.
The case dragged on for years. Humanists across Europe rallied to Reuchlin's side, and in 1515 and 1516 they published a comic masterpiece, the Letters of Obscure Men, a satire of his enemies in the guise of letters from ignorant monks.
In the end, Rome ruled against him in 1520, but by then the matter had become a symbol. The Reuchlin affair is often counted among the events that prepared the ground for the Reformation. His young relative Philipp Melanchthon, whom he recommended for a chair of Greek at Wittenberg, became one of Luther's closest allies.
A Complex Legacy
Reuchlin's record is mixed. He defended Jewish books at a time of violence and prejudice, and for this he deserves lasting respect. But his own aim was to bring Jews and Christians together through a Christian reading of the Kabbalah, and some of his writings contain the common prejudices of his time. He saw Hebrew learning as a tool for confirming Christian doctrine, not as an end in itself.
He died on June 30, 1522, shortly after taking a professorship at Tübingen. His books on Hebrew and the Kabbalah remained influential for generations.
Closing
A man who had never held a sword became the center of a European controversy because he thought a book was worth saving. In the process, he left a small treatise about the power of a single name. The sacred word, for Reuchlin, was a mystery to be approached with study and reverence, and it deserves to be read as a piece of Renaissance learning, with all its brilliance and its blind spots.
