What has been handed down to us is what we know to be authentic teaching. When you’re full immersed in truth, it’s really easy to notice what’s been changed, whether added to or removed.
The Arians and the Nestorians would say the same thing. This is the circularity of Orthodox thinking: those who are in Church know what the Church teaches because they are in the Church. As an Orthodox website admits:
Such reasoning is circular, because whoever accepts an authentic teaching is therefore inside the Church, but any who reject it are outside. In other words, such teachings are authentic essentially because those who hold to the teaching
declare themselves exclusively to be the Church.

No Bishop has the authority to change the Truth. What Jesus gave, they protect and teach.
And not Catholic Bishop has ever change (contradicted) what Jesus taught. If you disagree, please explain so that we can investigate the matter.
If any Bishop in the Orthodox Church did invent some new teaching, like Arius did, it & he would be condemned.
There doesn’t need to be a formal definition. Tradition is clear that the Theotokos, a human being and is Panagia.
The blatant error in the Pope’s definition is claiming the Panagia isn’t human like us, but by “singular grace” was created as a unique creature alone not affected by Ancestral Sin passed down from Adam & Eve, not a human being like us. We know this idea is not true because a. It’s a new teaching .
It was known to the Fathers, so new as of when?
Hippolytus (AD 235)
He [Jesus] was the ark formed of incorruptible wood. For by this is signified that His tabernacle [Mary] was exempt from defilement and corruption (Orat. In Illud, Dominus pascit me, in Gallandi, Bibl. Patrum, II, 496 ante [A.D. 235]).
Origen (AD 244)
This Virgin Mother of the Only-begotten of God is called Mary, worthy of God, immaculate of the immaculate, one of the one (Homily 1 [A.D. 244]).
Ephraim the Syrian (AD 361)
You alone and your Mother are more beautiful than any others, for there is neither blemish in you nor any stains upon your Mother. Who of my children can compare in beauty to these? (Nisibene Hymns 27:8 [A.D. 361]).
“
My Lady Most Holy, All-Pure, All-Immaculate, All-Stainless, All-Undefiled, All-Incorrupt, All-Inviolate …Spotless Robe of Him Who clothes Himself with light as with a garment …Flower unfading, purple woven by God, alone Most Immaculate.” (ibid.)
Ambrose of Milan (AD 387)
Come, then, and search out Your sheep, not through Your servants or hired men, but do it Yourself. Lift me up bodily and in the flesh, which is fallen in Adam. Lift me up not from Sara but from Mary, a Virgin not only undefiled but a Virgin whom grace has made inviolate, free from every stain of sin (ut incorrupta sit virgo, sed virgo per gratium ab omni integra labe peccati)." (Commentary on Psalm 118, 22-30 [A.D. 387])
Gregory Nazianzen
He was conceived by the virgin, who had been first purified by the Spirit in soul and body; for, as it was fitting that childbearing should receive its share of honor, so it was necessary that virginity should receive even greater honor (Sermon 38 [d. A.D. 390]).
Augustine (ca. AD 415)
Having excepted the Holy Virgin Mary, concerning whom, on account of the honor of the Lord, I wish to have absolutely no question when treating of sins,—for how do we know what abundance of grace for the total overcoming of sin was conferred upon her, who merited to conceive and bear Him in whom there was no sin?—so, I say again,
with the exception of the Virgin, if we could have gathered together all those holy men and women, when they were living here, and had asked them whether they were without sin, what do we suppose would have been their answer? …if they had been so questioned, would they not have declared with a single voice: “If we say we have no sin, we deceive ourselves, and the truth is not in us!”? (Nature and Grace 36:42 [A.D. 415]).
b. Facts get in the way - Mary suffered while on earth and we know she died prior to being taken bodily by Christ 3 days later And both of these things, suffering and death, are proof she inherited Ancestral Sin
Jesus suffered and died. Is that proof that He, too, inherited Ancestral Sin?
Adam and Eve were human like us. They didn’t begin their lives with “original sin”, either.
Did God create man with sin already within him? If not, then simply reflects humanity as it was intended, as we were all intended, to be.
