This food strengthens much, whether he receives sacramentally or virtually… He receives sacramentally when he communicates with the Blessed Sacrament. He receives virtually when he communicates, both by desire of communion and by contemplation of the Blood of Christ crucified… On seeing this, the soul becomes inebriated and blazes with holy desire… becoming full of love of [God] and for her neighbour.
Saint Catherine of Siena
