The two traditions of the Church are unified through the Assumption. Its not two traditions its one which cannot be verified, which lead to the second. If we go with John the Theologian then to we must admit all the visionaries.

Pope Pius XII, in Munificentissimus Deus, states…
'this feast shows, not only that the dead body of the Blessed Virgin Mary remained incorrupt, but that she gained a triumph out of death, her heavenly glorification after the example of her only begotten Son, Jesus Christ."
Then…
“that the Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory.”
This is what is required in belief. The idea Mary was assumed alive into heaven is ambiguous as this is not specifically stated and is derived from this point…“having completed here earthly course.”
In short no-where does the encyclical state; “Mary was Assumed Alive into Heaven”. And its left open intentionally. We do not have a witness who documented the account with Mary, nor does physical evidence exit, St Helena searched for Marys remains unsuccessfully, what we have is “visionaries” such as John the Theologian who can be read on New Advent. This is centuries later though. And why would we believe that and not Lourdes? False path for the debate, for as Mark of Ephesus stated, they “might be delusions” at Florence.
Now many Catholics may believe in Mary assumed alive or not. I believe Mary died and would have had it no other way, and I also am convinced She was incorrupt and Assumed into Heaven…“body and soul”.
See how easy both traditions fit.
If Elijah flew a Chariot, I can’t quantify why Mary can’t be assumed in Heaven, body and soul.
Since God required a pure Ark, the question remains why wouldn’t this be the same with Mary? Was the Ark worshipped? Of course not but it was venerated. And those who had issues with the Ark can be read about in 1 Chronicles `13;10-11, and those who cared for the Ark were Blessed 1 Chronicles 13:14
Christ is the Word made flesh, Mary is the Ark made flesh.
300 years before the Dogma Luther stated.
“… so that while the soul was being infused, she would at the same time be cleansed from original sin … And thus, in the very moment in which she began to live, she was without all sin.” (Martin Luther’s Works, vol 4, pg 694)
"God has formed the soul and body of the Virgin Mary full of the Holy Spirit, so that she is without all sins, " (ibid. vol 52, pg 39)
“. . . she is full of grace, proclaimed to be entirely without sin. . . . God’s grace fills her with everything good and makes her devoid of all evil. . . . God is with her, meaning that all she did or left undone is divine and the action of God in her. Moreover, God guarded and protected her from all that might be hurtful to her.” (Ref: Luther’s Works, American edition, vol. 43, p. 40, ed. H. Lehmann, Fortress, 1968)
Luthers comments being Catholic of course indicate the existing theological condition in the Church at the time, as does Bl Duns Scotus and St Thomas. The East remained with its original theology which by large can be read from the past.
Who was the “first” Christian? Did Mary need a Savior? {this is where Thomas Aquinas argument fell apart]
Mary needed a Savior more than anyone I would argue, since it was Marys prayer who found favor with God.
Christ, as the Church teaches, “conquered the enemy of the human race alone (solus)” (D711); In the same way, He alone acquired the grace of Redemption for the whole human race, including Mary…" (Dr. Ludwigg Otto, Fundamentals of Catholic Dogma 212-13)
“With God anything is possible”. Gospel X 2.
Jesus had to be born without Ancestral Sin transmitted to Mary. Or one is left to define how this was a completely human conception without the transmitting of Ancestral “sin”. We all fell. God chose Mary before She hit the ground.
Early Church Fathers. I don’t see the dispute.
It becomes you to be mindful of us, as you stand near Him who granted you all graces, for you are the Mother of God and our Queen. Help us for the sake of the King, the Lord God Master Who was born of you. For this reason you are called ‘full of Grace’…" (373 A.D., St. Athanasius)
Blessed Virgin, immaculate and pure you are the sinless Mother of your Son, the mighty Lord of the universe. You are holy and inviolate, the hope of the hopeless and sinful; we sing your praises. We praise you as full of every grace, for you bore the God-Man. We all venerate you; we invoke you and implore your aid…Holy and immaculate Virgin…be our intercessor and advocate at the hour of death and judgment…you are holy in the sight of God, to Whom be honor and glory, majesty, and power forever (373 A.D., St. Ephrem of Edessa) (catholicharboroffaithandmorals)
and
You alone and your Mother are more beautiful than the others; for here is no blemish in you, nor any stains upon your Mother. (Nisibene Hymns, 27:8, 370)
No Spot or Stain = Immaculate which means no pre existing condition of Ancestral Sin as stated above. Are they all wrong?
