A Rabbi is not conferred with a holy status and a special authority to carry out sacred rituals. He is just like any other member of Jewish Community, but with a greater amount of knowledge than the others.
Rabbi is simply a teacher and a leader who is sufficiently educated in Jewish Law (Halakhah) and tradition. His/her main duty is to be an instructor and assistant for the congregants who seek advice regarding the religious activities.
After obtaining the Rabbinical ordination or S'micha, rabbis inform and guide decisions at the synagogue. Their role is not only confined to being a spiritual leader, but an educator, a counselor and a role model.
Typical duties of an ordained Rabbi include leading spiritual services such as officiating at life-cycle events of Bat Mitzvahs and Bar Mitzvahs, weddings, funerals, baby naming ceremonies, High Holiday and Shabbat services on Yom Kippur and Rosh Hashanah.
A Rabbi is more than just an officiator of religious observances. He or she is the one required to encourage growth, and foster unity among his respective congregation and the greater community.
