Note 1 — Chapter IV · POPE DAMASUS AND THE BEGINNING OF RHYME.
Reading edition
Of course the champions of papal infallibility are at great pains to deny this. But all the contemporary writers, such as Athanasius, Hilary, and Jerome, assert it, and against it there is nothing but a priori assumptions and the assertion that the third Sirmian formula signed by Liberius has been mistaken for the first, which was Arian. In Dr. Newman’s Arians of the Fourth Century, pp. 433-40, there is a careful account of the three Sirmian formulas. The main fact never was denied until the necessities of the infallibility theory compelled the rewriting of history. Even the old Roman Breviary declares that “Liberius assented to the Arian mischief.”
