Lauchert wrote that in three later volumes Hontheim defended his book, as "Febronius" and various other pseudonyms, against a series of attacks. In addition to "Judicium academicum" from the University of Cologne (1765), refutations appeared from a large number of Roman Catholic authors, Lauchert lists titles by Pietro Ballerini, Tommaso Maria Mamachi, and Francesco Antonio Zaccaria. There were also refutations written from a Protestant standpoint, to repudiate the idea that a diminution of papal power was all that was necessary to bring the Protestants back into union with the Roman Catholic Church, for instance Lauchert lists titles by Karl Friedrich Bahrdt, Johann Friedrich Bahrdt, and Karl Gottlob Hofmann.
