Ed Ve-aluf (Witness and Leader) [punning on "Adolf"]
An essay entitled Ed Ve-aluf, written by the godly sage Father
A fellow of the German Pietist Yeshiva in Moravia.
Printed in the year 5507
The Latin name of this book is Testis et Doctor (which means that to the author at least Aluf here meant Teacher). The author was Adolph Groll (1681-1743), who was rector of the Piaristenkollegiums in Vienna. The book was originally printed in 1711, but this is from the 1747 edition.
The חסידים אשכנזי, or German Pietists were a 17th and 18th century Christian revival movement which found a parallel of sorts you-know-where. Am I allowed to quote Wikipedia?
"The Pietists wanted a deeper emotional experience rather than a preset adherence to form (no matter how genuine). They stressed a personal experience of salvation and a continuous openness to new spiritual illumination.They also taught that personal holiness (piety), spiritual maturity, Bible study, prayer, and fasting were essential towards "feeling the effects" of grace."This book, עד ואלוף, is a pretty run of the mill Christian Pietist text, except that it is in Hebrew and makes extensive use of Jewish sources to try to prove the truth of Christianity, which is why it was printed by missionary Johann Heinrich Callenberg, who also printed a Yiddish dictionary, and other missionary texts.
For example, the first chapter is called "How in the Future Hakadosh Baruch Hu will sit in Gan Eden and expound a new Torah, which is destined to be revealed through the Messiah," citing Midrash Yeshayahu 26. This is a real Midrash (link).
