Christian, Gustav Christopher, baptized at Nüremberg 1719, and died there about 1735. He was the author of two Judæo-German works—"Yesod Emunath Yeshua" (The basis of the Faith of Jesus), Berlin, 1712; and "Die Bekehrung's Israel," Schwabach, 1722.
Christiani, Friedrich Albrecht, was born in the middle of the seventeenth century, died at Prostnitz at the beginning of the eighteenth century. He was baptized in 1674 at Strassburg, having formerly been the Chazzan (Precentor) at Bruchsal. After having occupied for twenty years the chair of Semitics at the university of Leipzig, he retired to Prostnitz. Christiani's works comprise the following, all published at Leipzig. (1) "Zebah Pesah" (The sacrifice of Easter), an account of the Jewish celebration of Easter in the time of Jesus, and at the present. (2) "Seudath Purim" (The meal of Purim), 1677, a description of Jewish fasting and feasting. (3) "Zahakan Melumad Umethareth" (The Scholarly Gambler repenting) 1683, a German translation of the work of Leon of Modena on gambling. (4) "Abravanel's Commentary on the first prophets, with a Latin index," 1686. (5) "The text of Jonah with the Targum Massorah and the commentaries of Rashi, Ibn Ezra, Kimchi and Abravanel, and a Hebrew Latin Vocabulary," 1683. (6) "Iggereth" (Letter) 1676, The Epistle of St. Paul to the Hebrews, translated from the Greek into Hebrew. (7) "Traktat von dem Glauben und Unglauben der Juden," 1713.
Christiani, Moritz Wilhelm, born at Altorf at the end of the seventeenth century, died at Prague, 1740, probably a member of the Keyser family of Schleusingen, Bavaria. He claimed to have been a rabbi at Schleusingen before his baptism in 1715. Christiani wrote: (1) "Kurze Beschreibung einer Jüdischen Synagogue und eine Beschreibung der Synagogalen Gebraüche," Regensburg, 1723. (2) "Die Schlacht und Visiterkunst, ib., 1724." (3) "Ausgang von dem verstockten Judenthum und Eingang zum wahren Christenthum," an account of his conversion, his profession of faith, and several orations, Erfurt, 1720.

(5) "A German translation of the Sefer ha Minhagim of Jacob Levi (Matta Ril)," published at Bremen, 1733.
Christian, Friedrich Ernest (as a Jewish teacher called Abraham Saul), was baptized with his wife and two grown-up sons by Pastor Stemnitz in 1772.
Christmann was baptized in 1775.
Christlieb, Wilhelm, declared that it was a sermon which he heard preached to the Jews by Pastor Dekan Soldanus in the town hall of Cassel which convinced him of the truth of the Gospel. He was baptized in 1785.
Christlieb, Friedrich Wilhelm, another convert, made himself particularly obnoxious to the Jews by attacking the Talmud in a bitter spirit. He wrote: "Greuel der Verwüstung des heiligen Jerusalem durch den jüdischen Talmud," Cassel, 1681. "Lästerungen der Juden gegen Christum," ib., 1682. A theological treatise: "Jesus Christ und Sohn Gottes nach Kabbalistischer Art erwiesen," Rinteln, 1697.
Christhold, Christian Albert, born in 1687, was baptized when young with his mother. He had great talents, so that at the age of 23, in 1700, he was appointed Rector of the Gymnasium in Oettingen, when he wrote a Latin treatise advocating toleration and liberty to the Jews. He was afterwards a faithful minister of the Gospel till his death in 1772. Schulze said of him, "I have hitherto not found anyone like him."
Christhold, Christiane Sophie Magdalene (Judith), a relative of the above, followed his example.
Christfels, Philipp Ernst (Mordecai), born at Neuhaus, 1671, son of Moses Shemaja, received a good rabbinic and German education. Being of a disputatious disposition, he very often in his wanderings disputed with Christians on religious subjects, amongst whom was the well-known Wagenseil. A learned rabbi, by the name of Hirsch Froman, once advised him to read the New Testament. Another Rabbi, Abraham Reviga, Kabbalist, with whom he studied, intimated to him that under the attribute called Binah is to be understood the Son of God. This made him restless, but at the same time enquiring. He was finally, after nine months' instruction, baptized in 1701. Christfels was the author, before his baptism, of a book in Hebrew, entitled "Rephuah Hanephesh," "Soul-Medicine," and after he became a Christian, the Pentateuch with the Targum's and Rashi's commentaries were printed under his supervision.
