The other is major excommunication which deprives a man of the sacraments of the Church and of the communion of the faithful. Wherefore it is not lawful to communicate with one who lies under such an excommunication. But, since the Church resorts to excommunication to repair and not to destroy, exception is made from this general law, in certain matters wherein communication is lawful, viz. Moreover exception is made in favor of certain people whose business it is to be in attendance on the excommunicated person, viz. The others need no explanation.

For a heathen or a Jew is more separated from the Church than a person who is excommunicated. But one does not incur excommunication for communicating with a heathen or a Jew. Neither, therefore, does one for communicating with an excommunicated Christian. Further, if a man incurs excommunication for communicating with an excommunicated person, for the same reason a third would incur excommunication for communicating with him, and thus one might go on indefinitely, which would seem absurd. Therefore one does not incur excommunication for communicating with one who is excommunicated.
