Is Limbo a Capital 'T' Tradition & de fide?

[SFD]

Limbo is not a dogma and is not de fide. In point of fact, we just do not know. All we can do is to trust in God’s infinite divine mercy knowing that whatever he does, it will be the correct, proper, most just and most merciful solution.
Deacon Ed B

Limbo is not de fide. That is true.

The idea that we do not know anything certain about limbo is absolutely false. Limbo is based on de fide and theologically certain doctrine. The denial of limbo is not possible because of these certain doctrines and dogmas.

After looking at this thread I see it is full of proofs of what I am saying:

"…We say that a distinction must be made, that sin is twofold: namely, original and actual: original, which is contracted without consent; and actual which is committed with consent. Original, therefore, which is committed without consent, is remitted without consent through the power of the sacrament; but actual, which is contracted with consent, is not mitigated in the slightest without consent…The punishment of original sin is the depravation of the vision of God, but the punishment of actual sin is the torments of everlasting hell…" (See Denz.410, Pope Innocent III)

(The Roman Church) teaches…that the souls…of those who die in mortal sin, or with only original sin, descend immediately into hell; however, to be punished with different penalties and in different places.

And here are some sources that touch upon limbo itself or infants who die without baptism:
Synod of Pistoia:

The doctrine which rejects as a Pelagian fable, that place of the lower regions (which the faithful generally designate by the name of limbo of children) in which the souls of those departing with the sole guilt of original sin are punished with the punishment of the condemned, exclusive of the punishment of fire, just as if, by this very fact, that these who remove the punishment of fire introduced that middle place and state free of guilt and of punishment between the kingdom of God and eternal damnation, such as that about which the Pelagians idly talk,–false, rash, injurious to Catholic schools.

Council of Florence:

Regarding children, indeed, because of danger of death, which can often take place, when no help can be brought to them by another remedy than through than through the sacrament of baptism, through which they are snatched from the domination of the Devil and adopted among the sons of God, it advises that holy baptism ought not to be deferred for forty or eighty days, or any time according to the observance of certain people, but it should be conferred as soon as it can be done conveniently, but so that, when danger of death is imminent, they be baptized in the form of the Church, early without delay, even by a layman or woman, if a priest should be lacking.

Pius XII:

If what We have said up to now deals with the protection and the care of natural life, it should hold all the more in regard to the supernatural life which the newly born infant receives with Baptism. In the present economy there is no other way of communicating this life to the child who has not yet the use of reason. But, nevertheless, the state of grace at the moment of death is absolutely necessary for salvation. Without it, it is not possible to attain supernatural happiness, the beatific vision of God. An act of love can suffice for an adult to obtain sanctifying grace and supply for the absence of Baptism; for the unborn child or for the newly born, this way is not open.

16th Council of Carthage (aproved by Zosimus and Council of Ephases see above):

“It has been decided likewise that if anyone says that for this reason the Lord said: “In my father’s house there are many mansions”(JN14:2): that it might be understood that in the kingdom of heaven there will be some middle place or some place anywhere where the blessed infants live who departed from this life without baptism, without which they cannot enter into the kingdom of heaven, which is eternal life, let him be anathema.
For when the lord says :“Unless a man be born of water and the Holy Ghost, he shall not enter into the kingdom of God”(Jn3:5), what Catholic will doubt that he will be partner of the devil who has not deserved to be a co-heir of Christ? For he who lacks the right part will without doubt run into the left” (Denzinger 102 fn.2; 30th edition)

Pope St. Innocent I, in 417, Synod of Milevis : “The idea that infants can be granted the rewards of eternal life even without the grace of baptism is utterly foolish” (DS 219).

Pope Innocent III,
who asserted that those dying with only original sin on their souls will suffer " "no other pain, whether from material fire or from the worm of conscience, except the pain of being deprived forever of the vision of God” (Corp. Juris, Decret. l. III, tit. xlii, c. iii – Majores). (Denzinger 410)

John XXII, Nequaquam sine dolere, Nov 21, 1321:
“…the souls…of those who die in mortal sin, or with only original sin descend immediately into hell; however, to be punished with different penalties and in different places.” (Denzinger 493a)

Pope Pius VI, Auctorem Fidei, Aug. 28, 1794,
“Baptism” section 3:
“The doctrine which rejects as a Pelagian fable, that place of the lower regions (which the faithful generally designate by the name of the limbo of the children) in which the souls of those departing with the sole guilt of original sin are punished with the punishment of the condemned, exclusive of the punishment of fire, just as if, by this very fact, that these who remove the punishment of fire introduced that middle place and state free of guilt and of punishment between the kingdom of God and eternal damnation, such as that about which the Pelagians idly talk,–false rash injurious to Catholic schools.” [Denzinger 1526]

Pius XII-Allocution to midwives, October 29, 1951.
“An act of love is sufficient for the adult to obtain sanctifying grace and to supply the lack of baptism; to the still unborn or newly born this way is not open.”

The Holy Office in 1958 (now the Congregation for the Doctrine of the Faith) provided as follows:
“The practice has arisen in some places of delaying the conferring of Baptism for so-called reasons of convenience or of a liturgical nature–a practice favored by some opinions, **lacking solid foundation, concerning the eternal salvation of infants who die without Baptism…**Therefore this Supreme Congregation, with the approval of the Holy Father, warns the faithful that infants are to be baptized as soon as possible. . . . Pastors and preachers are exhorted to urge the fulfillment of this obligation.”

The provincial Council of Cologne:
“Faith teaches us that infants, since they are not capable of this desire, are excluded from the kingdom of heaven if they die [unbaptized].” (Collectio Lacensis, V. 320)

PS:
The Holy Innocents were martyrs for Jesus Himself. They died in his place therefore are martyrs .

Even so Jewish boys are circumcised at 8 days and received sanctifying grace. More than likely God in his providence would have allowed no births 8 or 9 days before Herod’s slaughter.

“We must say, therefore, that grace was bestowed in circumcision”
