Eunomius of Cyzicus
Continuing on with my series on the seven notes, I would call them tests, which Venerable John Henry Cardinal Newman developed for determining whether some aspect of Church teaching is a development of doctrine or a corruption of doctrine. We began with Note Six-Conservative Action Upon Its Past, and I would highly recommend that any one who has not read the first post in the series read it here before proceeding with this post. We will now take the remaining notes in numerical order. This post will deal with the First Note-Preservation of Type.
In regard to Preservation of Type, Cardinal Newman takes pains to point out that the idea underlying the doctrine remains of the same type while the external manifestations of the idea may change greatly. His illustration from Roman history conveys his point well:
On the other hand, real perversions and corruptions are often not so unlike externally to the doctrine from which they come, as are changes which are consistent with it and true developments. When Rome changed from a Republic to an Empire, it was a real alteration of polity, or what may be called a corruption; yet in appearance the change was small. The old offices or functions of government remained: it was only that the Imperator, or Commander in Chief, concentrated them in his own person. Augustus was Consul and Tribune, Supreme Pontiff and Censor, and the Imperial rule was, in the words of Gibbon, “an absolute monarchy disguised by the forms of a commonwealth.” On the other hand, when the dissimulation of Augustus was exchanged for the ostentation of Dioclesian, the real alteration of constitution was trivial, but the appearance of change was great. Instead of plain Consul, Censor, and Tribune, Dioclesian became Dominus or King, assumed the diadem, and threw around him the forms of a court.
In other words in determining whether there has been the preservation of type in a development of doctrine we must look at the substance and ignore the form. For example, in the Middle Ages laymen would often receive communion once a year out of great reverence for the body of Christ. Now we are encouraged to be frequent communicants. However, the underlying reverence that the Church commands for the body and blood of Christ remains the same.
Cardinal Newman concludes:
An idea then does not always bear about it the same external image; this circumstance, however, has no force to weaken the argument for its substantial identity, as drawn from its external sameness, when such sameness remains. On the contrary, for that very reason, unity of type becomes so much the surer guarantee of the healthiness and soundness of developments, when it is persistently preserved in spite of their number or importance.
