Judaism is one of the oldest monotheistic religions in the world (approximately 3,800 years old) and began with Biblical journey of an individual by the name of Abraham into the Land of Canaan some 1850 years before the common era.
Although Judaism is for many, primarily a religion, it is also seen by many others as a culture, an ethnicity, and/or a peoplehood, in which elements of language (Hebrew, Yiddish, Aramaic), land (the State of Israel) music, art, food, and literature also play a very important part.
As a religion, one of the most important aspects of Judaism is it’s theology that understands the Creator (God) as a single entity that has no human, animal or physical aspects. In a word, God within Judaism is “unseen” physically but manifests its presence in numerous ways through interaction with people and the world.
Another important aspect of Judaism is the “Covenantal” relationship between God and the Children of Israel (later to be known as Jews) that is found in the Hebrew Bible. Judaism believes that that “covenant” is still very much in effect today.
Beliefs in more detail
Belief in One God that has no physical properties. Judaism, (if one wants) can be involved in every aspect of one’s life from birth to death and everything in between. Judaism can be seen also as a way of life that includes philosophy, psychology, diet, and perhaps most importantly our behavior towards one another.
