Pope Shenouda III
The Lord Jesus Christ also said: "I am in the Father, and the Father in Me" (Jn. 14: 10), and repeated this expression once more: "believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves" (Jn. 14:11). The Lord means the works that reveal His Divinity such as the works of creating. He repeated the same relation in His soliloquy with the Father, saying: "You, Father, are in Me, and I in You" (Jn. 17:2 1). The Father in Him means that the Godhead dwells in Him, that is, the unity of Divinity with Humanity is in Him. The best explanation of this point are the words of St. Paul the Apostle about the Lord Jesus Christ: "For in Him dwells all the fullness of the Godhead bodily" (Col. 2:8,9). The in dwelling of the Godhead in Christ is the in dwelling of the Person of the Father in Him, like the in dwelling of light in the sun or the in dwelling of heat in fire or the in dwelling of thought in the mind, on condition that it is understood that both objects are one entity..
