Johann Peter Spaeth

Johann Peter Spaeth, also known as Moses Germanus or Moses Ashkenazi (1st half of the 17th century in Vienna – 27 April 1701 in Amsterdam) was an Austrian theologian that converted to Judaism.

Lutheran convert

Amid rumors of impending war, his father, a poor shoemaker, sought refuge between 1642 and 1645 at

.

In 1683 Spaeth returned to Catholicism, which he defended and praised in a work entitled Judicium Amoris de Fundamentalibus Quibusdam, Qui Feruntur Erroribus Ecclesiæ Romanæ. But this reconciliation did not last. New doubts assailed his mind; and after having mingled with the members of certain

tradition.

Convert to Judaism

It seems that Spaeth did not intend to become a proselyte to Judaism, and that his conversion was brought about, as he himself relates, through the following incident: Once a crucifix dropped from his pocket, and it was picked up by a Jew, who said: "It is Israel, the man of sorrow!" ^[2] Says Spaeth:

"From those words I understood the 53d chapter of Isaiah: the Jews bore the sins of the heathen, while they were daily persecuted by them. From time immemorial they had been treated in a shameful manner. As the whole history of the Passion tended to render the Jews odious, so the same sort of thing happens nowadays. For instance, the Jews are said to have murdered a child, and to have distributed the blood in quills for the use of their women in childbirth. I have discovered this outrageous fraud in time; and, therefore, I abandon Christianity, which permits such things."

Spaeth became converted at

, taking the name Moses Germanus.
