Abstract

Christian theology on the Eucharist, already since the Gospel of John refers to the scarcity and abundance of food, by linking this Sacrament to the hunger suffered by the Israelites in the desert and their further satiation with manna from heaven. Saint Albert the Great, in his reflection on the Eucharist, includes several ideas taken from his scientific knowledge, especially from Aristotle. These considerations build one of his personal contributions to theological understanding of the spiritualis manducatio that takes place in the Holy Mass. These explanations will be explored in order to understand in which sense the Eucharist is true food and true drink.
