Priest/Rabbi
Christianity and Judaism both involve a religious figure who leads the people in worship, these are known as the priest and the rabbi respectively (though there are many other names and titles for this position). The priest or rabbi leads the service by teaching the people about God, praying and interpreting readings from the Torah or the Bible. These sermons usually take place inside a Church or Synagogue either on Sunday or Sabbath (Saturday), special services are given on days of religious importance. The priest as rabbi also participate in ceremonies such as baptism and circumcision.

At the beginning, the rabbi (or 'teacher') was the leader of the synagogue, and the leaders of Judaism were the religious figures in charge of the Temple. However, after the Temple was destroyed, the rabbi was then seen as the religious leader of Judaism.  The rabbi's duties include the teaching of the people about Judaism, interpreting the Torah and rabbinic writings, as well as informing the Jewish people how the laws written in these writings should be observed. More recently, the rabbi has taken on more duties, which have actually been adopted from the Christian clergy. He will participate in synagogue services by reading the Torah and preaching the sermon, like the priest does in Churches. The rabbi will also perform official duties during marriages and funerals. As the rabbi is also a spiritual leader, he will often represent the Jewish community in Jewish and non-Jewish events.
