Roman Catholicism hasn't got a clue about its origins

This is just simply excellent in every way.

Roman Catholicism, as a religion, is a novelty of the late fourth century, but in order to be taken seriously she must at every opportunity claim Nicæan and ante-Nicæan origins for her novelties. Yet at the same time, there is nothing so foreign to Roman Catholicism as the Nicæan and ante-Nicæan Church. For this reason, while Roman Catholicism constantly attempts to lay claim to apostolicity, she must always at the same time distance herself from the practices and beliefs of the Church of the apostles. It is a love-hate relationship. Rome strives diligently to identify herself with the apostolic era, and then exhausts herself explaining why the Church of that era was so different from Roman Catholicism. What we find as we examine Rome’s vain striving for antiquity and continuity is an uncomfortable truth that lies beneath the surface of all of her posturing, a truth that can never be uttered aloud: She does not know whence she came. ...

To summarize, we simply recall that Rome’s attempts to find Papal Primacy in the 6th Canon of Nicæa is founded upon a gross anachronism. Pope Leo’s attempts to find impute Roman judicial primacy to Nicæa was wholly fraudulent. Bryan Cross’s attempts to place the primacy of the Three Petrine sees in Ignatius of Antioch and Canon 6 of Nicæa required that he impute a late-fourth century teaching retroactively upon the Early Church. Rome’s attempts to find Pontifex Maximus used in the Early Church is based upon Tertullian’s use of the title as an insult. The attempt to place the exhumation and veneration of martyr’s relics before Nicæa required that a late-fourth century practice be incorrectly placed in 312 A.D.. Pius IX’s attempts to impute the Immaculate Conception to the Early Church was found to be a terrible historical inaccuracy. Roman Catholic attempts to prove an ante-Nicæan belief in Mary as the Ark of the New Covenant required a misrepresentation of Hippolytus, and relied upon other documents known to be fraudulent and spurious. Roman Catholic criticism of the allegedly “anti-incarnational” worship of Protestants required evidence from the late fourth century and beyond, because the Early Church was apparently “anti-incarnational” in its worship, too, by Roman Catholic standards. The Sacrifice of the Mass cannot be found at Nicæa, and does not finally find an advocate until Gregory of Nyssa in 382 A.D.. Early proof of the perpetual virginity of Mary required a later modification to the Nicæan creed, and relied upon the words of Athanasius, 35 years removed from the Council. The allegation of the “continuity” of kneeling on the Lord’s Day since the first century required that a thousand years of explicit prohibitions of the practice be ignored, including Nicæa’s outright prohibition of the practice.

In other words, there is at least a 300-year gap between the apostolic era and Rome’s novelties. And importantly, that does not leave a lot of time for doctrines to develop. Rather, they seemed instead to emerge spontaneously. We noted above, in reference to Cardinal Newman’s “Development of Doctrine,” that he attributed the later emergence of Roman Catholic teachings to an unbroken, continuous process of doctrinal development since the apostolic era. But what we find when we examine the historical origins of Roman Catholicism is not a gradual, continuous emergence of the doctrines since the age of the apostles, but rather a sudden, step-wise emergence of error at the end of the fourth century.

And to cover up her later origins, Rome consistently, perpetually, instinctively and relentlessly lavishes her affections upon the Council of Nicæa.

But Nicæa stubbornly refuses to requite them.
