Elohim is the One Living God, but Elohim is not a federation or union of three separate gods. The Living God is a single God. There are no other gods than this One God. However the One God exists always as the Most High, the Angel and the Spirit. As soon as we define one of these Three as a “separate being” then we have destroyed the definition of Elohim. For a Muslim, as for Aristotle, the word “person” means “an individual being”. It is this underlying assumption about ‘being’ that we must address. In the Bible the being of God is Three Persons. Matthew 28:19 “…go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit…”
If we have followed the logic of the Scriptures we can see that the Most High, the Divine Mediator and the Spirit cannot act individually. To accomplish any of their works they utterly depend on each other precisely because they are together the single Living God.
