Abicht, Johann Georg. Tauf-Actus, welcher bey der heiligen Taufe eines gebohrnen Judens, Isaac Joseph Leib, nun Christian Leib genandt.

An account of the conversion to Protestantism of the Jew, Isaac Joseph Leib. Records in detail the baptism ceremony whereby Isaac Joseph Leib (who took the name Christian Leib) answered questions related to his new faith and publicly abjured his former Jewish allegiances. Johann Georg Abicht (1672-1740) a Protestant Hebraist, was professor of Hebrew at the University of Wittenberg. Many German Christian Hebraists of the 18th-century demonstrated a new open-mindedness towards Judaism. The aims they pursued in their Hebrew research were, at least in part, thoroughly scientific, even if usually linked with a covert hope – or in this case the clear intention - for Jewish conversion.
