Abstract
The aim of the current article is to highlight the original arguments through which the conspicuous 13th century Franciscan theologian Matteo d’Acquasparta (1240–1302) supports the belief in the Virgin Mary’s immediate resurrection and her assumption with body and soul into heaven. To this end, we methodologically resort to primary sources through a detailed analysis of our author’s Mariological writings on the subject. In this regard, we have followed his argumentative approaches step by step to base his defense of the Assumptionist thesis on the various essential aspects that structure it. Our analytical investigation thus reveals the originality and conviction with which this Franciscan scholar firmly defended the belief in the Assumption of Mary, with body and soul, into heaven.
