Let us understand, therefore, that this Sacrament is a medicine for poor, spiritually sick people…And since we see only bread and wine, yet we do not doubt that he accomplishes spiritually in our souls all that he demonstrates to us outwardly through these visible signs, namely, that he is the heavenly bread that feeds and nourishes us for eternal life. So let us be grateful for the infinite goodness of our Saviour, who spreads out all his riches and goods on this table to distribute them to us.”
