The main hypothesis of the investigation consists of relating and determining parallelisms between the sources written, relative to the specific text of the Creed, and their pictorial representation in the plasmation of faith articles, since they are assigned of systematic form to each apostle. 
The documentary sources in which these premises have been examined have based on neotestamentary texts, patrístics texts, liturgical texts, and doctrinals texts. 
Fundamental in this study it has been the accomplishment of the detailed iconographic analysis of each figure that conforms the Apostolate of the Creed. Detailing to its form of representation and customized characterization through its personal attributes.
The purpose of the investigation project has consisted of defining, locating, to compile, as well as to catalogue of reasoned form, and comparativily to analyze a series of artistic representations determined by the context historical-cultural-monk of centuries XVII and XVIII, in the regions and provinces of the Valencian scope.
