Christ is present in the Holy Sacrament of the altar. There have been numerous
heretical teachers who have denied the Catholic doctrine of Our Lord’s presence
in the Holy Eucharist and have given various interpretations to his words: “This
is My body; this is My blood.” Consequently the Council of Trent declared that
Christ is truly, really, and actually present in the Blessed Sacrament. He is
present in the Holy Sacrament truly, consequently, not as it were in an image.
He is, moreover, really present and not merely so in a spiritual sense. Finally,
He is actually present and not only by the actions of his grace. An artist once
conceived the idea of refuting those erroneous doctrines by means of his brush.
He painted a picture wherein Christ was portrayed seated at the Last Supper and
on the same canvas were Luther and Zwingli. Beneath the picture he inscribed
these words: Christ says: “This is My body.” Luther says: “This will become my
body.” Zwingli says: “This symbolizes my body.” Which of the three is right?
This brief description is more convincing than a multitude of arguments.
