The above is antithetical to Catholic doctrine.
“***The Hypostatic Union was never interrupted (sent. certa.)***…***The Hypostatic Union will never cease (de fide)***” (Ott. L., Fundamentals of Catholic Dogma, p. 150-151)
The redeeming love of Jesus “always united him to the Father” (CCC 603).
With regard to the creedal affirmation “he descended into hell”…
According to St. Thomas Aquinas, an angel is said to be “in a place” by the application of his power to the place. Non-corporeal substances are not “contained” by the place they are in, but more correctly said to "virtually contain" the thing or place by their their angelic power. Similarly, St. Thomas taught that Christ’s soul is “in a place” by the application of His power to the place. His power virtually contains the thing or place by the power of His soul. But Christ’s soul can be said to apply power *per suum effectum *(through His effect) and *per suum essentiam *(through His essence).
St. Thomas taught:
"A thing is said to be in a place in two ways. First of all, through its effect, and in this way Christ descended into each of the hells, but in different manner. For going down into the hell of the lost He wrought this effect, that by descending thither He put them to shame for their unbelief and wickedness: but to them who were detained in Purgatory He gave hope of attaining to glory: while upon the holy Fathers detained in hell solely on account of original sin, He shed the light of glory everlasting.
In another way a thing is said to be in a place through its essence: and in this way Christ’s soul descended only into that part of hell wherein the just were detained. so that He visited them “in place,” according to His soul, whom He visited “interiorly by grace,” according to His Godhead. Accordingly, while remaining in one part of hell, He wrought this effect in a measure in every part of hell, just as while suffering in one part of the earth He delivered the whole world by His Passion."
"***Christ, who is the Wisdom of God, penetrated to*** *all the lower parts of the earth*, not passing through them locally with His soul, but by spreading the effects of His power *per suum effectum] in a measure to them all: yet so that He enlightened only the just* [per suum essentiam]: because the text quoted continues: "And I will enlighten all that hope in the Lord."
(St. Thomas Aquinas, *Summa Theologica, *III, 52, 2)
St. Thomas contends that Christ’s soul, descended into hell by application of his power per suum effectum, to both the hell of the damned and the prison of the just. Yet, also asserted that Christ’s soul, *per suum essentum et effectiam *descended into the prison of the just. It was by the application of his essence and effective power, according to Christ’s soul, that “He visited ‘interiorly by grace,’ according to His Godhead.” (St. Thomas, ibid.).
He was never apart from the Godhead.
***Therefore, Christ soul after bodily death and before resurrection can rightly be said to be “in the place” of damned, the place of the limbo of the fathers, and the place of heaven, all simultaneously, but in a different sense.
…Not just physical death, but the spiritual death that we would all have were it not for His Sacrifice.
Incorrect. John Paul II affirmed in the Catechism of the Catholic Church, "**In his human soul united to his divine person, the dead Christ went down to the realm of the dead. He opened heaven’s gates for the just who had gone before him. **(CCC 637).
In his General Audience teaching, John Paul II states, “***The Apostle [Peter] adds however: “<In spirit (Christ) went and preached to the spirits in prison>” (1 Pt 3:19). This seems to indicate metaphorically the extension of Christ’s salvation to the just men and women who had died before him.***”
