Judaism and Christianity.
Judaism gas a certain attitude to Christianity. Christianity is like its child-religion, which brings the basic elements of Judaism to the people all over the world.
In the competent Judaist literature there is no opinion about how to treat to Christianity: or it is paganism with its dogmas, which were written in 4th century and unacceptable by Jews, or it is acceptable by Jews form of monotheism, that is known in Toseft as “shituf”. It means worship to God with some additional ones.
Christianity has appeared in historical religious context of Judaism. Jesus and his followers (apostles) were Jews by their birth and by their education. Many Jews accepted them as one of Judaist sects.
In Judaist opinion the personality of Jesus from Nazareth doesn`t have real religious sense. The Jews do not accept him as messiah, so the title “Christos” is inadmissible. In Judaist religious texts there is no any mention about some personality, who could be real Jesus.

Judaism and Islam.
Interaction of Judaism and Islam began in 7th century with the arriving and propagation of Islam in Arabian Peninsula. Muhammad affirmed that belief that he proclaimed is a pure religion of Abraham. And this belief was distorted by Jews and Christians later on. Thus, they proclaimed Judaism a religion of lie and Judaist religious texts, as distorted.
Jews accept Islam, as monotheistic religion. It is allowed to Jew even to pray in mosque in extreme situations. In Middle Ages Islam theology and Islam culture have influenced in philosophy of Judaism extensively.
Traditionally, Jews, living in Islam countries were allowed to practice their religion and to control their affairs. They were free in choice of place of living and profession. The Ottomans Empire was a shelter for Jews, who were banished from the territory of Spain by Catholic Church.
But in opinion of Islam law, Jews in Islam countries did not possess all rights. Using the protection of the life and their property they had to avow the complete domination of Islam in all spheres of society life.
Today Islam treats Judaism as hostile religion, associating it with Zionism. It is based on political situation – confrontation of Israel and Arab-Islam world.
