You at present have no capacity to comprehend it. So its absurd.There is a difference between an internal contradiction and a mystery that we struggle to understand. A full empty bottle of water is not understandable but not in the same way as trying to understand the relativity of time. Chalking up an absurd contradiction as a "mystery" is empty philosophy and Paul warned us about that (Colossians 2:8).
Jesus eternal? YES. But, the great mistake that Trinitarians made is assuming falsely that Jesus existed as the Son from eternity when the Bible clearly teaches that His existence as the Son had a beginning (Luke 1:35 and Galatians 4:4). There was simply no reason to offer up an absurd contradiction of an "eternally begotten Son", when logically and Biblically everything is against such a thing.
You keep giving verses on the pre-existence of Christ, but NONE of these verses call him "Son" in eternity. He wasn't called the "Son" until he was actually a real "Son" due to a real conception and begetting (Luke 1:35).
Simply call Jesus the one true God from eternity who became the Son of God for our redemption.
God was manifested in the flesh (1 Timothy 3:16), not God the Son.
Good. Not every one has the same intolerance.
I knew a world renown chef who could not grasp Gary Larson's the 'Far Side." It was just absurd to him. Brilliant chef. But?
So be it.
The Son of God preexisted the Incarnation. The Soul of Jesus was in union with Jehovah before Jesus was born.
Here are some OT examples of Jehovah of the OT having both Deity and Soul. God is 'spirit." God is not 'soul.'
And they began to remove the foreign gods from their midst and to serve Jehovah,
so that his soul became impatient because of the trouble of Israel. Judges 10:16
Jehovah himself examines the righteous one as well as the wicked one, and anyone
loving violence his soul certainly hates." Psalm 11:5
“Bring no more futile sacrifices; Incense is an abomination to Me. The New Moons,
the Sabbaths, and the calling of assemblies— I cannot endure iniquity and the sacred
meeting. Your New Moons and your appointed feasts my soul hates; They are a trouble
to Me, I am weary of bearing them.. Isa 1:13-14
Some will understand. Those who fail to? Let them think it absurd if that gives them comfort.
