And God said unto Moses,
I AM THAT I AM:
and he said,
Thus shall you say unto the children of Israel, I AM has sent me unto you.

The phrase “I am” belongs to the divinity. It does not change with time but is always there and remains eternal. So the reply to Moses was “I am who I am” and again “He who is has sent me.” But we must first investigate why God alone claims this term which denotes essence for himself. When it was spoken, there were angels, heavenly creatures and all earthly creatures as were decreed to exist. But because he is the only uncreated and eternal nature which did not begin in time and subsists as one divinity in three persons, God alone is rightly said to be, for he needs no one for his existence but ever abides by the strength of his own power. In it there is another mystery: a single syllable, sum (“I am”), is embraced by three letters, so we are taught that the holy Trinity is one God.
