- In “Grace and Consanguinity”, still an unpublished work,, Prof. Antonio Moreno Almárcegui discusses the impact of the Christian revolution in Europe on the concept, meaning and practice of Marriage. He approaches this question from a historical perspective. He bewails the absence of a sincere dialogue on the effect of Christianity on the changes that took place in the cultural practice of marriage in Europe. His purpose is to explain that Christianity had a profound effect on marriage meaning and practice in Europe, especially as concerns the interrelationship between Grace and consanguinity. Could a historian speak of supernatural phenomena? And if it does, How must deal with it? For Moreno, answering this question is central to his argument against the Philippe Aries and his ilk, that the transformation of the family in Europe took shape in the early 17th century when children and their education became the central theme for the European families.
