This is why God is Triune (a Trinity of Persons) because God, knowing all things perfectly, also knows His own infinite essence perfectly (and He alone is capable of complete knowledge of His own infinite and eternal Divine Nature). The Father’s eternal knowledge of Himself, His eternal self-reflection, His eternal Thought of Himself, literally is Himself. The Son is the eternal Thought, Word, or Logos, of the Father. This is why the beginning of St. John’s Gospel says: “In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came to be through him, and without him nothing came to be.” (John 1:1-3) The Father knows all things in Himself, including Himself. The “Self” known is the Son, and the created things known are creatures. This is why it says, “all things came to be through Him, and without Him nothing came to be”. Apart from God, there literally is no thing. Nothing exists of itself except God, and all things that exist or can possibly exist, are known eternally in the infinite Mind of God; the infinite Thought of the Father.
The Son is the mirror image of the Father. Sacred Scripture says: “He is the image of the invisible God, the firstborn of all creation. For in him were created all things in heaven and on earth, the visible and the invisible, whether thrones or dominions or principalities or powers; all things were created through him and for him. He is before all things, and in him all things hold together.” (Colossians 1:15-17) We also read: “He reflects the glory of God and bears the very stamp of his nature” (Hebrews 1:3). The Eternal Son reflects the Eternal Father; all the Love, Beauty and Goodness in the Son originated in the Father; since Two are One in Essence, hence, Jesus says, “The Father and I are one.” (John 10:30) The Son is Infinite, Omnipotent, and Eternal, just like the Father. He is the equal of the Father in every way. This is why Jesus said: “He who has seen me has seen the Father” (John 14:9) and, “The Son can do nothing of his own accord, but only what he sees the Father doing; for whatever he does, that the Son does likewise” (John 5:19). And again, “The words that I say to you I do not speak on my own authority…and the word which you hear is not mine but the Father’s who sent me” (John 14:10,24). Notice how Jesus says that the Son sees all that the Father sees and does in like manner. This would be possible only if the Son were equal to the Father, as only God can see and know all that the Father sees and knows.
You may be thinking that this is good to know, and hopefully interesting, but still wondering what this has to do with the beatific vision, but I promise, we are getting to that. Please bear with me.
