Myth of Jesus, page-951

God or Jehovah IS a Title, not Name as such.
-----------
God is a title .
(1 Corinthians 8:5) For even though there are so-called gods, whether in heaven or on earth, just as there are many “gods” and many “lords,”
(1 Corinthians 8:6) there is actually to us one God, the Father, from whom all things are and we for him; and there is one Lord, Jesus Christ, through whom all things are and we through him.

In order to distinguish the "one God" from the 'many “gods” ', he has revealed his personal name, JEHOVAH.
(Psalm 83:18) May people know that you, whose name is Jehovah, You alone are the Most High over all the earth. - NWT.

That men may know that thou, whose name alone is JEHOVAH, art the most high over all the earth. - KJV
