Ah, I see you have actually not read Fr.Cekada's article then. There are several theologians who taught that BoD is a dogma, and Fr.Cekada names some of them. All others treat it as a Catholic doctrine or Catholic teaching.
Your example of Limbo is flawed, because though many had tended to favor St.Augustine's view, no theologian held the contrary opinion could not be maintained - that's why the matter was freely discussed in the schools.
But now all theologians have held that the contrary opinion is not lawful, at least after Trent. And this common and constant consent of theologians binds us. The matter is settled, not open to dispute.
If you don't like theologians, I gave the example of a Saintly priest earlier, here is a Saintly mystic, a very pious and humble soul, herself receiving a reflection on a text of a Saintly Apostle.
"I wished thee to see the secret of the Heart, showing it to thee open, so that you mightest see how much more I loved than I could show thee by finite pain. I poured from it Blood and Water, to show thee the baptism of water which is received in virtue of the Blood. I also showed the baptism of love in two ways, first in those who are baptized in their blood shed for Me which has virtue through My Blood, even if they have not been able to have Holy Baptism, and also those who are baptized in fire, not being able to have Holy Baptism, but desiring it with the affection of love. There is no baptism of desire without the Blood, because Blood is steeped in and kneaded with the fire of Divine charity, because through love was it shed."
Thus it is written in Sacred Scripture also, of the water, the blood and the spirit that flowed from the Sacred Heart - that the three are one, and so the threefold baptism is one, it is Trinitarian.
If you believe as St.Alphonsus did, you will find that the true doctrine never lessens, but rather increases the missionary zeal that should burn in all Catholics to save souls that are in danger of perishing. This was true of St.Alphonsus.
