These are matters and questions intimately connected with the Christian meaning of freedom and liberation. The data expounded in the first part of this Letter show that Mariology is alive and active in relevant questions in matters doctrinal and pastoral. However it is necessary that the study of Mariology, together with attention to the pastoral problems which are emerging gradually, attend to rigorous research, conducted according to scientific criteria. 28 Teaching thus given will avoid one-sided presentations of the figure and mission of Mary, presentations which are detrimental to the whole vision of her mystery. Sound teaching will be a stimulus to deep research B in seminaries and through the writing of licence and doctoral theses B into the sources of Revelation and the documents.
Mariological study can also profit from interdisciplinary teaching.
With regard to this latter point, we would draw attention to the Norms of the Apostolic Constitution Sapientia Christiana which provide for licences and doctorates in theology, specializing in Mariology. 31 the Congregation for Catholic Education wishes to reaffirm the necessity of furnishing seminarians and students of all centres of ecclesiastical studies with Mariological formation which embraces study, devotion and life-style.
