” Wherefore We command most strictly and in virtue of holy obedience, all the faithful of whatever state, grade, condition, order, dignity or pre-eminence, whether clerical or lay, secular or regular, even those who are entitled to specific and individual mention, that none, under any pretext or for any reason, shall dare or presume to enter, propagate or support these aforesaid societies of Liberi Muratori or Francs Massons, or however else they are called, or to receive them in their houses or dwellings or to hide them, be enrolled among them, joined to them, be present with them, give power or permission for them to meet elsewhere, to help them in any way, to give them in any way advice, encouragement or support either openly or in secret, directly or indirectly, on their own or through others; nor are they to urge others or tell them, incite or persuade them to be enrolled in such societies or to be counted among their number, or to be present or to assist them in any way; but they must stay completely clear of such Societies, Companies, Assemblies, Meetings, Congregations or Conventicles, under pain of excommunication for all the above mentioned people, which is incurred by the very deed without any declaration being required, and from which no one can obtain the benefit of absolution, other than at the hour of death, except through Ourselves or the Roman Pontiff of the time.”
The secret societies, such as the Freemasons, Skulls and Bones, Illumanati etc. are to be avoided at all costs. The Church has condemned the societies infallibly due to the fact that these societies engage in activity in which involve persecuting the Church through plot, spreading errors of modernism, practicing the rituals of the occult, and revolution against Catholic Truth, as we have seen in France, 1789–1799.
If any Catholic, whether laymen, religious, clergymen etc. joins or associates with any of the above listed organizations, or anything similar, then according to the 1917 Code of Canon law you are automatically excommunicated from the Holy Roman Catholic Church.
Canon 2335: “Those who join a Masonic sect or other societies of the same sort, which plot against the Church or against legitimate civil authority, incur ipso facto an excommunication simply reserved to the Holy See”. If anybody is a member of the Freemasons or any similar organization, for the salvation of your soul, repent and leave this organization now.
