The Bar/Bat Mitzvah ceremony takes place during the Sabbath (Saturday) worship service. The first part of the service ends with the congregation singing Mi Chamocha, which in English means "Who is like you among the Gods?" It refers back to the songs sung by the Isrealites at the shores of the Red Sea when they were saved from the Egyptians by Moses.
The second part of the service ends with a prayer for peace for the Jewish people and the world.
During the third part of the service the child reads from the Five Books of Moses, or otherwise known as the Torah. Then a section from the Phrophetic Writings, called Haftarah is read by the child. That part is then concluded with a hope that everybody in the world will embrace God's words.
The entire service ends with two prayers: Aleinu, a plea that the humanity will accept that there is only one God, and Kaddish, a mourner's prayer that states that the fulfillment of God's hopes will come one day.
The ultimate message of the service is a message of hope. "A hope for freedom, peace, and universal redemption" (Salkin).
