To emphasize the practical dimensions of Aquinas’ doctrine of man in the image of God, I propose to examine the relationship of this doctrine to both the Church’s sacraments and the practice of divine friendship.
It is easiest to tell what transubstantiation is by saying this: little children should be taught about it as early as possible. Not of course using the word “transubstantiation”, because it is not a little child’s word. But the thing can be taught, and it is best taught at mass at the consecration, the one part where a small child should be got to fix its attention on what is going on. I mean a child that is beginning to speak, one that understands enough language to be told and to tell you things that have happened and to follow a simple story. Such a child can be taught then by whispering to it such things as: “Look! Look what the priest is doing … He is saying Jesus’ words that change the bread into Jesus’ body. Now he’s lifting it up. Look! Now bow your head and say ‘My Lord and my God’,” and then “Look, now he’s taken hold of the cup. He’s saying the words that change the wine into Jesus’ blood. Look up at the cup. Now bow your head and say ‘We believe, we adore your precious blood, O Christ of God’.” [The cry of the Ethiopians at the consecration of the chalice.] This need not be disturbing to the surrounding people.
