In Old Testament, more exactly in Hebrew Bible, one of the primary names of God (usually translated “God”) into English is the noun elochim, the word written in the same way as plural noun elochim, meaning “gods” (as in the phrase “pagan gods”). We conclude that God is the community of gods.
Well, God is a mathematical object that has many different representations. One (not only) of the representations of God is the community of gods. New Testament more specifically says (1Jn 4:8, 16) “God is love”, that is God (in one of His representations) is love between gods, love in their community.
We know from Sumerian legends that gods (elochim in Sumer language, which is translated “gods”, from where the Hebrew word “elochim” was copied) visited the Earth. In other words, we had their community visiting the Earth, that is a God’s visit. Apparently Sumerian knew gods but didn’t know God. Abraham and later Moses received the revelation of united God, God as the community of love.
Apparently gods visited the Earth later on, too. Consider legends about elves.
In New Testament (written in Greek) the grammar of the word God is different: “gods” are signified by the plural “teoi” of the word “theos”. And God as “o teos”, that is God with an article (“the God” in English). In New Testament (the) God is represented to people by one certain god, the “standard” God whose words should be abided. Apparently it means “god of the Earth” (see Rev. 11:4). Old Testament warns many times not to serve to a foreign God (not the god of the Earth) – that’s like betraying your country and becoming an aliens’ spy. One certain elf is assigned to rule the Earth. I think that now he is Jesus.
