The Trinity (Father, Son, Holy Spirit). Catholics only believe in One God.
Surprisingly many things are common in Hinduism & catholicism. One most important thing is that both Religion believe in one Supreme God.
What you say is true about Islam and Judaism and Catholicism: all come from the one God. Only Catholicism is based on the coming of God as man, Jesus, the son of God, who always was one with God the father and God the Holy Spirit. Catholicism does not teach against any other religion
Catholicism is the fulfillment of the old testament story and is the new and everlasting covenant with God
Christ aka God the Son
The important thing is that Catholicism knows one God only.
There is no official "Supreme God", like Zeus is in Greek mythology. However if one were to give the title of "Supreme God" to a Norse God it would have to be Odin.
God, Gold, and Glory was often described as the Spanish's driving force throughout the New World, and they were Catholics, but no, it doesn't mean Catholicism.
If you believe people made up the concept of God, then people also made up "the will of the supreme being." If you believe that God is a real supreme being, then the will of the supreme being was not given to God, but something God possesses and man simply recognizes.
There's none as "supreme god". God itself is considered as "supreme". The shape and form we give to offer prayers is upto each individual.
