Jewish Answer

There are 1000's of laws in Judaism, similar to secular law found in any country today. These laws are called 'halachot' (pl) and are recorded in the Talmud. There is no ranking of these laws, all are equally important.

In regard to the mitzvot (guidelines) found in the Torah, including the 10 Statements, there is also no ranking. Each guideline is as important as the next.
