Since I am not a Catholic, i'd present another view of Free masonry here. As a background, the issue of Free Masonry was taken up in the Southern Baptist Convention in the US, sometime in 1993. It caused a rift between conservatives and moderates. In the end,they concluded "that membership in a Masonic order was the business of the individual, not the church". Others suspected that Masons were behind the historic vote, since a number of masons are southern baptists.
The Eight Problems With Freemasonry (As reported by the Home Missions Board, SBC, 1350 Spring Street NW, Atlanta, GA 30367-5601)

1. The prevalent use of offensive concepts, titles, and terms such as "Worshipful Master" for the leaders of the lodge; references to their buildings as "mosques," "shrines," or "temples"; and the use of such words as "Abaddon" and Jah-Bul-On," the so-called secret name of God. To many, these terms are not only offensive but sacrilegious.
2. The use of archaic, offensive rituals and so-called "bloody oaths" or "obligations," among those being that promised by the Entered Apprentice: [listed in original] or that of the Fellow Craft degree: [listed in original] Or that of the Master Mason: [listed in original] Or that of other advanced degrees with required rituals considered by many to be pagan and incompatible with Christian faith and practice.
Even though these oaths, obligations and rituals may or may not be taken seriously by the initiate, it is inappropriate for a Christian to "sincerely promise and swear," with a hand on the Holy Bible, any such promises or oaths, or to participate in any such pagan rituals.
3. The recommended readings in pursuance of advanced degrees, of religions and philosophies, which are undeniably pagan and/or occult, such as much of the writings of Albert Pike, Albert Mackey, Manly Hall, Rex Hutchins, W.L. Wilmhurst and other such authors; along with their works, such as Morals and Dogma, A Bridge to Light, An Encyclopedia of Freemasonry and The Meaning of Masonry.
4. The reference to the Bible placed on the altar of the lodge as the "furniture of the lodge," comparing it to the square and compass rather than giving it the supreme place in the lodge.
5. The prevalent use of the term "light" which some may understand as a reference to salvation rather than knowledge or truth.
6. The implication that salvation may be attained by one's good works, implicit in the statement found in some
Masonic writings that "Masonry is continually reminded of that purity of life and conduct which is necessary to obtain admittance into the Celestial Lodge above where the Supreme Architect of the Universe presides." (LA Monitor, page 79)
Even though many Masons understand that the "purity of life and conduct" can only be achieved through faith in Jesus Christ, others may be led to believe they can earn salvation by living a pure life with good conduct.
7. The heresy of Universalism (the belief all people will eventually be saved), which permeates the writings of many Masonic authors, which is a doctrine inconsistent with New Testament teaching.
8. The refusal of most lodges (although not all) to admit for membership African Americans.
On the positive side, the report commended the Masons for its many charitable endeavors, hospitals, burn centers. It acknowledged that many outstanding Christians and Southern Baptists now and in the past have been Masons.
They recognized that many of the tenets and teachings of some Grand Lodges could be considered compatible and supportive of the Christian faith and practice, such as a strong emphasis on honesty, integrity, industry and character and the insistence that every member believe in [a] God. The report then quoted a number of Biblical quotes from the Texas Monitor to show that there are some explicit references to the Christian faith.
However, the report cautioned that "To be sure, not all Grand Lodges affirm Christian Doctrine, and many do not declare Jesus as the unique Son of God; but many do, and for this we commend them."(Ibid.)
Their final statement concludes with this:
"We exhort Southern Baptists to prayerfully and carefully evaluate Freemasonry in the light of the Lordship of Christ, the teachings of the Scripture, and the findings of this report, as led by the Holy Spirit of God" (Ibid.)
And we say that if a Christian Mason truly did that he would honestly have to leave the Lodge.
