FIRST: This is beyond sophomoric. It would be useful to first get a proper understanding of the Magisterium.

The criteria for Papal Infallibility were defined infallibly by the First Vatican Council in Pastor Aeternus, chapter four, as quoted below (with my numbering added). There are five criteria.
It must involve:

1. “the Roman Pontiff”
2. “in virtue of his office, when as the supreme shepherd and teacher of all the faithful, who confirms his brethren in their faith (cf. Lk 22:32),”
3. “by a definitive act, he proclaims”
4. “a doctrine of faith or morals” (“And this infallibility…in defining doctrine of faith and morals, extends as far as the deposit of revelation extends”)
5. “in accordance with revelation itself, which all are obliged to abide by and be in conformity with”

It is the infallible teaching of the Catholic Church that each and every one these criteria must be met for a teaching to be infallible, if it is taught by the Pope alone. (The Pope can also teach infallibly in union with the other Bishops, as discussed below.)

Therefore, whenever the Pope teaches by his own authority, yet without meeting all the criteria for an infallible Papal teaching, his teaching is non-infallible and it falls under the non-infallible Ordinary Magisterium, not the infallible Sacred Magisterium.

Historically, the Popes have only occasionally taught under Papal Infallibility; they have most often taught under the non-infallible Ordinary Magisterium.

SECOND: The very foundational infallibility that informs as to what books constitute the Holy Bible does not disappear into its interpretation. Interpretation confirms why these books were chosen and the books reinforce the interpretation provided by one Church. Otherwise we’ll have the rotting by-products of Protestantism as reflected in the Rev, Jeremiah Wrights, Al Sharptons, Jimmy Swaggarts, David Koresh’s, Jehovah’s Witnesses, Mormons, and the snake dancing Christian pastors in Kentucky

THIRD: The list of authors you cite don’t even make for a footnote in major scholarship publications. On the other hand, Aquinas and Augustine have colleges and universities named for them all over the world by their profound theological insights of sacred scripture and tradition.

FOURTH: That bread you talk about, upon consecration, it becomes the Body and Blood of Christ. Don’t take my word for it.

The Church has consistently understood Christ’s words to be literally referring to His True Flesh and Blood, as is evident in the writings of the early Church saints like:

St. Ignatius of Antioch (50-107 A.D.)
St. Justin Martyr (100-165 A.D.)
St. Irenæus of Lyons (125-203 A.D.)
St. Ambrose (340-397 A.D.), and
St. Cyril of Jerusalem (315-386 A.D.)

Although all the faithful in the Church have always believed in the concept of transubstantiation, there was no need to formally define it until 1215, the Fourth Lateran Council dogmatically which said: that while the outward appearances of bread and wine remain {the taste, touch, smell and looks}, their inward realities or substance has become the living Christ. Because Jesus is truly present — Body, Blood, Soul and Divinity — we adore the Eucharist with profound reverence.

Here’s a definitive compendium of writings that has withstood centuries of scholarship and research and caused hundreds of Protestant theologians to convert to Catholicism.

Oh, but don’t tell this to the low-information Al-Sharpton Christian Protestants!

Ignatius of Antioch

“I have no taste for corruptible food nor for the pleasures of this life. I desire the bread of God, which is the flesh of Jesus Christ, who was of the seed of David; and for drink I desire his blood, which is love incorruptible” (Letter to the Romans 7:3 [A.D. 110]).

“Take note of those who hold heterodox opinions on the grace of Jesus Christ which has come to us, and see how contrary their opinions are to the mind of God. . . . They abstain from the Eucharist and from prayer because they do not confess that the Eucharist is the flesh of our Savior Jesus Christ, flesh which suffered for our sins and which that Father, in his goodness, raised up again. They who deny the gift of God are perishing in their disputes” (Letter to the Smyrnaeans 6:2–7:1 [A.D. 110]).

Justin Martyr

“We call this food Eucharist, and no one else is permitted to partake of it, except one who believes our teaching to be true and who has been washed in the washing which is for the remission of sins and for regeneration [i.e., has received baptism] and is thereby living as Christ enjoined. For not as common bread nor common drink do we receive these; but since Jesus Christ our Savior was made incarnate by the word of God and had both flesh and blood for our salvation, so too, as we have been taught, the food which has been made into the Eucharist by the Eucharistic prayer set down by him, and by the change of which our blood and flesh is nurtured, is both the flesh and the blood of that incarnated Jesus” (First Apology 66 [A.D. 151]).

Irenaeus

“If the Lord were from other than the Father, how could he rightly take bread, which is of the same creation as our own, and confess it to be his body and affirm that the mixture in the cup is his blood?” (Against Heresies 4:33–32 [A.D. 189]).

“He has declared the cup, a part of creation, to be his own blood, from which he causes our blood to flow; and the bread, a part of creation, he has established as his own body, from which he gives increase unto our bodies. When, therefore, the mixed cup [wine and water] and the baked bread receives the Word of God and becomes the Eucharist, the body of Christ, and from these the substance of our flesh is increased and supported, how can they say that the flesh is not capable of receiving the gift of God, which is eternal life—flesh which is nourished by the body and blood of the Lord, and is in fact a member of him?” (ibid., 5:2).

Clement of Alexandria

“’Eat my flesh,’ [Jesus] says, ‘and drink my blood.’ The Lord supplies us with these intimate nutrients, he delivers over his flesh and pours out his blood, and nothing is lacking for the growth of his children” (The Instructor of Children 1:6:43:3 [A.D. 191]).

Tertullian

“[T]here is not a soul that can at all procure salvation, except it believe whilst it is in the flesh, so true is it that the flesh is the very condition on which salvation hinges. And since the soul is, in consequence of its salvation, chosen to the service of God, it is the flesh which actually renders it capable of such service. The flesh, indeed, is washed [in baptism], in order that the soul may be cleansed . . . the flesh is shadowed with the imposition of hands [in confirmation], that the soul also may be illuminated by the Spirit; the flesh feeds [in the Eucharist] on the body and blood of Christ, that the soul likewise may be filled with God” (The Resurrection of the Dead 8 [A.D. 210]).

Hippolytus

“‘And she [Wisdom] has furnished her table’ [Prov. 9:2] . . . refers to his [Christ’s] honored and undefiled body and blood, which day by day are administered and offered sacrificially at the spiritual divine table, as a memorial of that first and ever-memorable table of the spiritual divine supper [i.e.,
the Last Supper]” (Fragment from Commentary on Proverbs [A.D. 217]).

Origen

“Formerly there was baptism in an obscure way . . . now, however, in full view, there is regeneration in water and in the Holy Spirit. Formerly, in an obscure way, there was manna for food; now, however, in full view, there is the true food, the flesh of the Word of God, as he himself says: ‘My flesh is true food, and my blood is true drink’ [John 6:55]” (Homilies on Numbers 7:2 [A.D. 248]).

Cyprian of Carthage

“He [Paul] threatens, moreover, the stubborn and forward, and denounces them, saying, ‘Whosoever eats the bread or drinks the cup of the Lord unworthily, is guilty of the body and blood of the Lord’ [1 Cor. 11:27]. All these warnings being scorned and contemned—[lapsed Christians will often take Communion] before their sin is expiated, before confession has been made of their crime, before their conscience has been purged by sacrifice and by the hand of the priest, before the offense of an angry and threatening Lord has been appeased, [and so] violence is done to his body and blood; and they sin now against their Lord more with their hand and mouth than when they denied their Lord” (The Lapsed 15–16 [A.D. 251]).

Council of Nicaea I

“It has come to the knowledge of the holy and great synod that, in some districts and cities, the deacons administer the Eucharist to the presbyters [i.e., priests], whereas neither canon nor custom permits that they who have no right to offer [the Eucharistic sacrifice] should give the Body of Christ to them that do offer [it]” (Canon 18 [A.D. 325]).

Aphraahat the Persian Sage

“After having spoken thus [at the Last Supper], the Lord rose up from the place where he had made the Passover and had given his body as food and his blood as drink, and he went with his disciples to the place where he was to be arrested. But he ate of his own body and drank of his own blood, while he was pondering on the dead. With his own hands the Lord presented his own body to be eaten, and before he was crucified he gave his blood as drink” (Treatises 12:6 [A.D. 340]).

Cyril of Jerusalem

“The bread and the wine of the Eucharist before the holy invocation of the adorable Trinity were simple bread and wine, but the invocation having been made, the bread becomes the body of Christ and the wine the blood of Christ” (Catechetical Lectures 19:7 [A.D. 350]).

“Do not, therefore, regard the bread and wine as simply that; for they are, according to the Master’s declaration, the body and blood of Christ. Even though the senses suggest to you the other, let faith make you firm. Do not judge in this matter by taste, but be fully assured by the faith, not doubting that you have been deemed worthy of the body and blood of Christ. . . . [Since you are] fully convinced that the apparent bread is not bread, even though it is sensible to the taste, but the body of Christ, and that the apparent wine is not wine, even though the taste would have it so, . . . partake of that bread as something spiritual, and put a cheerful face on your soul” (ibid., 22:6, 9).

Ambrose of Milan

“Perhaps you may be saying, ‘I see something else; how can you assure me that I am receiving the body of Christ?’ It but remains for us to prove it. And how many are the examples we might use! . . . Christ is in that sacrament, because it is the body of Christ” (The Mysteries 9:50, 58 [A.D. 390]).

Theodore of Mopsuestia

“When [Christ] gave the bread he did not say, ‘This is the symbol of my body,’ but, ‘This is my body.’ In the same way, when he gave the cup of his blood he did not say, ‘This is the symbol of my blood,’ but, ‘This is my blood’; for he wanted us to look upon the [Eucharistic elements] after their reception of grace and the coming of the Holy Spirit not according to their nature, but receive them as they are, the body and blood of our Lord. We ought . . . not regard [the elements] merely as bread and cup, but as the body and blood of the Lord, into which they were transformed by the descent of the Holy Spirit” (Catechetical Homilies 5:1 [A.D. 405]).

Augustine

“Christ was carried in his own hands when, referring to his own body, he said, ‘This is my body’ [Matt. 26:26]. For he carried that body in his hands” (Explanations of the Psalms 33:1:10 [A.D. 405]).

“I promised you [new Christians], who have now been baptized, a sermon in which I would explain the sacrament of the Lord’s Table. . . . That bread which you see on the altar, having been sanctified by the word of God, is the body of Christ. That chalice, or rather, what is in that chalice, having been sanctified by the word of God, is the blood of Christ” (Sermons 227 [A.D. 411]).

...

“What you see is the bread and the chalice; that is what your own eyes report to you. But what your faith obliges you to accept is that the bread is the body of Christ and the chalice is the blood of Christ. This has been said very briefly, which may perhaps be sufficient for faith; yet faith does not desire instruction” (ibid., 272).

Council of Ephesus

“We will necessarily add this also. Proclaiming the death, according to the flesh, of the only-begotten Son of God, that is Jesus Christ, confessing his resurrection from the dead, and his ascension into heaven, we offer the unbloody sacrifice in the churches, and so go on to the mystical thanksgivings, and are sanctified, having received his holy flesh and the precious blood of Christ the Savior of us all. And not as common flesh do we receive it; God forbid: nor as of a man sanctified and associated with the Word according to the unity of worth, or as having a divine indwelling, but as truly the life-giving and very flesh of the Word himself. For he is the life according to his nature as God, and when he became united to his flesh, he made it also to be life-giving” (Session 1, Letter of Cyril to Nestorius [A.D. 431]).
