But in the Greek myths, one learns that the gods were capricious, jealous, and would plot one against the other. There was no universal sense or moral code of a loving God in whom one would find Divine Law, and a God who cared and loved His Creation. The Jewish faith from which we draw our root was the first on earth to attach ethics to belief in One God - ethical monotheism. The only other culture previous that had attempted monotheism was in Egypt some 100 years before Moses (and only for a short time did it last), and it proposed one god but had no worked-out ethical system as did the Hebrews.
And in Christianity, one finds that our God loved the world so that He sent His only-begotten Son for our Salvation, and taught us of good vs. evil. The closest competition to Christianity at the beginning, apart from Gnosticism which despised the physical world, was Mithraism which basically had a god (Mithras) worshiped by Roman soldiers in caves with little worry of good and evil. Christianity didn’t murder and pile up slaves or children to be buried with their ruler (pharoah, Far East emperor, or for that matter Viking warlord later) to ease the chief’s journey to the under world or to Valhalla. Each soul was to be equal before God, prince and pauper, healthy and ill, alike.
The other great close-by religion of the time, apart from the Greeks, were the Zoroastrians and also the later followers of Manes (Manichaeism) in Persia- unlike these, Christians did not believe in a Dualistic universe where a good god fights against an equally powerful evil god. In Christianity, Goodness is Supremely Powerful and “absolute evil” cannot exist as all evil is basically a tortured warping of or absence of good. God is Good and All-Powerful. There is no room, as in Manichaeism, for an equally powerful Evil Force. Evil is not equally strong. All is subject to God.
Look to Greek mythology and see if you can find the Beatitudes attached to a belief in One Loving Omnipotent, Benevolent God would be my start. Just my two cents.
