For all Catholics in this thread who are crazily and vigorously defending Freemasonry against the Church please read Pope Leo XIII’s Encyclical on the subject.
By the way if you read para 11 the Pope points out “What We have said, and are about to say, must be understood of the sect of the Freemasons taken generically, and in so far as it comprises the associations kindred to it and confederated with it, but not of the individual members of them. There may be persons amongst these, and not a few who, although not free from the guilt of having entangled themselves in such associations, yet are neither themselves partners in their criminal acts nor aware of the ultimate object which they are endeavoring to attain.”

A few extracts in case you don’t want to read the document although it has only 38 paras:
- The first warning of the danger was given by Clement XII in the year 1738,[3] and his constitution was confirmed and renewed by Benedict XIV.[4] Pius VII followed the same path;[5] and Leo XII, by his apostolic constitution, Quo Graviora,[6] put together the acts and decrees of former Pontiffs on this subject, and ratified and confirmed them forever. In the same sense spoke Pius VIII,[7] Gregory XVI,[8] and, many times over, Pius IX.[9]
8…Our intention, following the example of Our predecessors, directly to treat of the masonic society itself, of its whole teaching, of its aims, and of its manner of thinking and acting, in order to bring more and more into the light its power for evil, and to do what We can to arrest the contagion of this fatal plague.
- If those who are admitted as members are not commanded to abjure by any form of words the Catholic doctrines, this omission, so far from being adverse to the designs of the Freemasons is more useful for their purposes. First, in this way they easily deceive the simple-minded and the heedless, and can induce a far greater number to become members. Again, as all who offer themselves are received whatever may be their form of religion, they thereby teach the great error of this age – that a regard for religion should be held as an indifferent matter, and that all religions are alike. This manner of reasoning is calculated to bring about the ruin of all forms of religion, and especially of the Catholic religion, which, as it is the only one that is true, cannot, without great injustice, be regarded as merely equal to other religions.
- What, therefore, sect of the Freemasons is, and what course it pursues, appears sufficiently from the summary We have briefly given. Their chief dogmas are so greatly and manifestly at variance with reason that nothing can be more perverse. To wish to destroy the religion and the Church which God Himself has established, and whose perpetuity He insures by His protection, and to bring back after a lapse of eighteen centuries the manners and customs of the pagans, is signal folly and audacious impiety. Neither is it less horrible nor more tolerable that they should repudiate the benefits which Jesus Christ so mercifully obtained, not only for individuals, but also for the family and for civil society, benefits which, even according to the judgment and testimony of enemies of Christianity, are very great. In this insane and wicked endeavor we may almost see the implacable hatred and spirit of revenge with which Satan himself is inflamed against Jesus Christ. – So also the studious endeavor of the Freemasons to destroy the chief foundations of justice and honesty, and to co-operate with those who would wish, as if they were mere animals, to do what they please, tends only to the ignominious and disgraceful ruin of the human race.
31…As Our predecessors have many times repeated, let no man think that he may for any reason whatsoever join the masonic sect, if he values his Catholic name and his eternal salvation as he ought to value them.** Let no one be deceived by a pretense of honesty**. It may seem to some that Freemasons demand nothing that is openly contrary to religion and morality; but, as the whole principle and object of the sect lies in what is vicious and criminal, to join with these men or in any way to help them cannot be lawful.
For those who think the threat of excommunication has been lifted because they cannot see it in the New Canon Code, this is not the case. There is a provision for such a sanction in cases, to be identified locally, where an organisation works against the Faith or the Church (Canon 1374).
Also in 1983 Congregation of the Doctrine of the Faith said
Masonic membership is a grave sin.
