As usual, much support for those particularly Romanist views come by way of argument of assertion, as has long been the case. Though there can indeed be found support for certain peculiarities from 4th century and onward writers, going backwards in time from there to the actual time of the Apostles can be seen to be increasingly problematic, the closer to Christ we travel.
I was just reading again Farber's The Difficulties of Romanism
in which he defines the term he uses, Romanism, itself. I am much persuaded by his treatment not only of that, but of pretty much all the rest, difficult as it is to digest, lengthily written as it is in early 19th century style, albeit fairly repetitive throughout (as is the case with many scholarly works), it is still quite clear.
