GOD-title name or Concept?

Since God is a 6th Century Germanic term: 1) what is the name of the deity we personally serve? 2) What is the name of our Eternal Father that was given to Prophets and Apostles and those who served the Will of the Kosmos? 3) How can human concept of God built on Scholastics, Syllogism and Exegeses based doctrinal dogma- A dogma that different religion and different people use to personalize their God—give us pure knowledge of Elyon (Most High) Creator? 4) Can we the created beings give our own character attributes to the Supreme Creator and Maker-the Kosmic intelligence of the Universe? 5) How can we be in the Full Will and Full Service of our Eternal Father when we don’t even know the True Names to call Eternal Father and Supreme Creator? 6) Is not the powers of those names (Yahweh Elyon/Yeshua) that will give us Cosmos and victory over Lucifer and Angels on earth? 7) Should the supreme Creator fit into our philosophy or should we fit in His divine philosophy?
