Arcana Coelestia #15
15. Throughout heaven they do not know any other Father than the Lord, for They are one, as He Himself has said,
I am the way, the truth, and the life. Philip said, Show us the Father. Jesus said to him, Have I been with you so long, and yet you do not know Me, Philip? He who has seen Me has seen the Father. So why do you say, Show us the Father? Do you not believe that I am in the Father and the Father in Me? Believe Me that I am in the Father and the Father in Me. John 14:6, 8-11.

Philip said to him, "Lord, show us the Father, and that will be enough for us."

Jesus said to him, "Have I been with you such a long time, and do you not know me, Philip? He who has seen me has seen the Father. How do you say, 'Show us the Father?'
10
Don't you believe that I am in the Father, and the Father in me? The words that I tell you, I speak not from myself; but the Father who lives in me does his works.

Believe me that I am in the Father, and the Father in me; or else Believe me for the very works' sake.
