Albert the Great on the Eucharist as True Food

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.
