Christianity has a close relationship with Judaism, both historically and theologically. Jesus, his disciples, Paul (who wrote most of the New Testament), and the members of the earliest Christian churches were all Jews. Jesus' family followed Jewish customs and Jesus frequently quoted the Hebrew Bible. Jesus' followers believed him to be the messiah, a Jewish figure predicted in the Jewish Bible.
Despite its Jewish origins, it was not long before Christianity regarded itself as something other than a new Jewish sect. The first Christian council, described in the New Testament, concluded that pagan converts to Christianity did not have to follow Jewish ritual laws. Soon, converts to Christianity were almost exclusively pagans and Christianity moved further away from Judaism.
In the 2,000 years of history since Jesus, the relationship between Christianity and the ancient faith in which it is rooted has often been strained. Christians have criticized Jews for rejecting Jesus as their messiah and Jews have criticized Christians for corrupting the concept of one God and following a false messiah. The New Testamant reports Jews persecuted Christians; after Christians became the more powerful group, they frequently persecuted Jews.
