Note ON Section 41, PAGE 143
There is so close an agreement, both in substance and often in the form of expression, between the preceding sections (36-42) and the so-called Athanasian Creed, that it led Antelmi (Nova de Symb. Athanas. Disquisitio,) to ascribe that document to Vincentius as its author, and to suppose that in it we have the fulfilment of the promise here referred to. If, however, the Creed was the work of Vincentius, it cannot well be the work promised at the close of § 41, for Vincentius's words point to a fuller and more explicit treatment of the subjects referred to, whereas in the Athanasian Creed, though the subjects are the same, the treatment of them is very much briefer and more concise.
Whoever was the author however, if it was not Vincentius, he must at least, as the subjoined extracts seem to prove, have been familiar with the Commonitory, as also with St. Augustine's writings, of which, as well as of the Commonitory, the Creed bears evident traces. I subjoin the following instances of agreement between the Commonitory and the Creed: Antelmi gives several others.
