Reply: In the negative; for Communism is materialistic and anti-Christian; and the leaders of the Communists, although they sometimes verbally profess that they are not attacking religion, in fact, nevertheless, by doctrine and action show themselves to be enemies of God and of the true religion and the Church of Christ.
2. Whether it is licit to publish, propagate, or read books, periodicals, daily papers, or sheets which promote the doctrine or action of Communists, or to write in them.
Reply: In the negative: for they are forbidden _ipso iure_ (see Canon 1399).
3. Whether the faithful who knowingly and freely do the acts mentioned in 1 and 2 can be admitted to the sacraments.
Reply: In the negative, according to the ordinary principles governing the refusal of the sacraments to those who are not properly disposed.
4. Whether the faithful who profess the materialistic and anti-Christian doctrine of Communists, and especially those who defend or propagate it, incur _ipso facto_ as apostates from the Catholic faith the excommunication specially reserved to the Holy See.
Reply: In the affirmative (Decree of the Holy Office, July 1, 1949).
The sanction of excommunication specially reserved to the Holy See was imposed also upon those who teach boys and girls in associations set up by the Communists to imbue youth with principles and training which are materialistic and contrary to Christian morality and faith. The associations themselves are subject to the sanctions of the decree of July 1, 1949. Moreover parents or guardians who send their children to such associations, and the children themselves, as long as they have part in these associations, cannot be admitted to the reception of the sacraments (Monitum of the Holy Office, July 28, 1950).
(c) seditious societies, that is, those organizations, even though not secret, which aim at the overthrow of family and property rights;
(d) suspect societies, that is, those whose principles or methods have the appearance of being unsound. On January 11, 1951 the Holy Office in response to the question: “Whether Catholics may join the ‘Rotary Club’?” issued the following decree: “It is not licit for clerics to join the Association ‘Rotary Club’ or to be present at its meetings; the laypeople are to be urged to preserve the prescript of Canon 684.” The decree seems to have taken many English-speaking people by surprise, one paper describing it as “a bewildering document.” The surprise flowed from personal experience of Rotary Clubs as social clubs dedicated to bonhomie and community improvement. Nevertheless, the decree was in accord with the general trend of Church policy in regard to undenominational societies. They are not approved; they are not condemned as Masonry has been condemned. What is their position? The response that layfolk are to be exhorted to observe Canon 684 is indicative of the attitude of the Church in regard to such societies. The canon instructs them to “beware of secret, condemned, seditious and suspect societies.” Since Rotary Clubs are seldom considered to be secret and never as condemned nor as seditious, the implication is that they are suspect. Such was the interpretation of the decree given in the _Osservatore Romano_ of Jan. 27, 1951.
