His Excellency notes that an excommunication is
a declaration, based on solid evidence, that the actions or public teachings of a particular Catholic are categorically incompatible with the teachings of the Church. It is intended primarily as a means of getting the person who is in grave error to recognize the depth of his error and repent. A second reason, while somewhat secondary but no less important, is to assure the faithful who truly are faithful that what they believe to be the teaching of the Church is true and correct. Allowing their faith to be shaken or allowing them to be confused when Catholics publicly affirm something contrary to faith or morals, seemingly without consequences, scandalizes and confuses the faithful. This is no small matter. The Church, and particularly bishops, have an obligation to defend the faith but they also have an obligation to protect the faithful. We do not generally see the dissidence of public figures as something that harms the faithful but it has a deleterious effect upon them.Seeking to further clarify what it means to declare someone excommunicate, the Bishop used an old metaphor of the Bishop as a spiritual doctor:
This declaration no more causes the excommunication than a doctor who diagnoses diabetes causes the diabetes he finds in his patient. The doctor recognizes the symptoms and writes the necessary prescription. Accusing the doctor of being a tyrannical power monger would never cross anyone’s mind. Even when the doctor tells the patient that they are “excommunicated” from sugar it is clear that his desire is solely the health of his patient. In fact, a doctor who told his diabetic patient that he could keep ingesting all the sugar he wanted without fear would be found grossly negligent and guilty of malpractice.
In the same way, bishops who recognize a serious spiritual malady and seek a prescription to remedy the error, after discussion and warning, may be required to simply state, “What you do and say is gravely wrong and puts you out of communion with the faith you claim to hold.” In serious cases, and the cases of misled Catholic public officials are often very serious, a declaration of the fact that the person is de facto out of communion may be the only responsible and charitable thing to do.
Failing to name error because of some kind of fear of offending the person in error is neither compassion nor charity. Confronting or challenging the error or evil of another is never easy yet it must be done.
