J. H. Newman's quest for the true Church of Christ forced him to fathom the problem. The result of this quest was Newman's theory of doctrine development presented in 1845 in his Essay on the Development o f Christian Doctrine, which distinguishes seven criteria of validity and authenticity of developmental form. These criteria, characterised by Newman in a general way, find their detailed extensions and application in an analysis of specific problems of Mariology and allow a final statement that contemporary Mariology is the result of the development of the Mariological doctrine of the Church in the first centuries.plAttribution-NonCommercial-NoDerivs 3.0 Polandhttp://creativecommons.org/licenses/by-nc-nd/3.0/pl/John Henry Newmanmariologiaekumenizmteologiateolodzyteologowiedoktryna chrześcijańskachrześcijaństwokardynałowiekapłaniduchowieństwohistoria KościołaBibliaPismo Świętekatolicyzmanglikanizmwiarakult MaryiMaryjapobożność maryjnareligijnośćreligijność ludowaMariologyecumenismtheologytheologiansChristianitycardinalsclergypriesthoodChurch historyBibleCatholicismAnglicanismfaithcult of MaryMaryMarian devotionreligiousnesspopular pietyhistoriahistoryChurchKościółkultcultkult maryjnyArticle
