There is one! And it has been around for nearly as long as humanity itself. 
Seven Universal Commandments were given to our mutual ancestor Noah and thus to mankind. These teachings were later instructed to us by Moses, at Mt. Sinai, along with the foundational principles and values of the Torah.
These represent a set of principles of faith, existence and living around which all of mankind can unite, regardless of nationality or background.
Sinai Education is an online learning community for all people who are eager to learn and unify around this universal message.
