The book by Pinchas Polonsky, a scientist, specialist in modern problems of Judaism and interreligious dialogue, author of many books, considers them as the past. so does the possible future relationship between Judaism and Christianity, analyzing similarities and differences, as well as imaginary differences when established prejudices create the wrong picture. The current state of the Judeo-Christian dialogue and ideas for its development are discussed. From the author's point of view, the main thing to overcome mutual misunderstanding is. to realize that. Although Judaism and Christianity are incompatible things, and the Jewish people have not become and will not become Christian, nevertheless, historically these two religions complement each other. From the Jewish point of view, the rejection of the incarnation of Jesus does not at all deny that providence determined his mission to become the "divine instrument" through which a huge part of humanity came to the Almighty, and this is a great merit of Christianity. The book is intended for historians, theologians, and religious scholars: for anyone who wants to understand Christianity, Judaism, and the dialogue between them.
