The great codifier of Torah law and Jewish philosophy, Rabbi Moshe ben Maimon ("Maimonides" also known as "The Rambam"), compiled what he refers to as the Shloshah Asar Ikkarim, the "Thirteen Fundamental Principles" of the Jewish faith, as derived from the Torah. Maimonides refers to these thirteen principles of faith as "the fundamental truths of our religion and its very foundations." The Thirteen Principles of Jewish faith (as recorded in Maimonides' introduction to Perek Chelek) are as follows:
1. Belief in the existence of the Creator, who is perfect in every manner of existence and is the Primary Cause of all that exists.
2. The belief in G-d's absolute and unparalleled unity.
3. The belief in G-d's non-corporeality, nor that He will be affected by any physical occurrences, such as movement, or rest, or dwelling.
4. The belief in G-d's eternity.
5. The imperative to worship G-d exclusively and no foreign false gods.
6. The belief that G-d communicates with man through prophecy.
7. The belief in the primacy of the prophecy of Moses our teacher.
8. The belief in the divine origin of the Torah.
9. The belief in the immutability of the Torah.
10. The belief in G-d's omniscience and providence.
11. The belief in divine reward and retribution.
12. The belief in the arrival of the Messiah and the messianic era.
13. The belief in the resurrection of the dead.
It is the custom of many congregations to recite the Thirteen Articles, in a slightly more poetic form, beginning with the words Ani Maamin--"I believe"--every day after the morning prayers in the synagogue.
