Article 34

In the thirty-fourth article, the question is raised whether the body of Christ in the sacrament is not moved when the host is moved. (See also, S.Th., III, q. 76 a. 6.)

It is true to say that his body is not moved as bodies are moved per se or accidentally in a place because it is not in the place in which the sacrament is in the way in which bodies are in a place per se or accidentally. His body has another relationship to the sacramental dimensions than a body has to its own dimensions (according to which it is moved per se or accidentally). But in the way in which it belongs to the body of Christ to be in a place by reason of the sacramental dimensions, it belongs to it to be moved in place.
