His Holiness Christ said: "The Father is in me." This we must understand through logical and scientific evidences, for if religious principles do not accord with science and reason, they do not inspire the heart with confidence and assurance.
It is said that once John of Chrysostom was walking along the seashore thinking over the question of the trinity and trying to reconcile it with finite reason; his attention was attracted to a boy sitting on the shore putting water into a cup. Approaching him, he said, "My child, what art thou doing?" "I am trying to put the sea into this cup," was the answer. "How foolish art thou," said John, "in trying to do the impossible." The child replied, "Thy work is stranger than mine, for thou art laboring to bring within the grasp of human intellect the conception of the trinity."
Let us, free from past tradition, investigate the reality of this matter. What is the meaning of the father and the son?
This fatherhood and sonship are allegorical and symbolical. The Messianic reality is like unto a mirror through which the sun of divinity has become resplendent. If this mirror expresses "The light is in me" - it is sincere in its claim; therefore Jesus was truthful when he said, "The Father is in me."
The sun in the sky and the sun in the mirror are one, are they not? - and yet we see there are apparently two suns.
