The assertion that God is One, is part of the mystique of numbers. If God is identical with the number one, He must have qualities in common with this number. There is no such thing as an Absolute One. "One" simply represents a synthesis of conflicting forces. Man is one because he is a synthesis of body, soul and spirit. These again are a synthesis of other entities. An atom is a synthesis of conflicting elementary particles. The Hebrew language has two expressions for the word "One". Absolute unity and composite unity. God is called a Composite Unity - a plural word - "Eloheinu" : We maintain that God is divisible, because number one is divisible - Father, Son and Holy Ghost. All God's children share His divine Nature. John 10:34, "Ye are gods." (We are made god, but GOD remains ONE.)
The number one is also capable of being multiplied, but unlike all other numbers, because however much one multiplies it by itself it always remains one. "One" is the only number whose square root is equal to itself: That is why Jesus, as man, was able to say, "He that hath seen me hath seen the Father."
So we have retained the saying of the early Christians, "Every time you look at a brother you look at God."
God has been called One, because every number is a quantity related to One and so the whole creation is related to God.
