I found this very informative article from the website of the Militia of the Immaculata, founded by St. Maximilian Kolbe
Freemasonry, contrary to public perception, is a secret society rather than a fraternity. Its principles are fundamentally contrary to the Catholic faith and explicitly deny key tenets of Christianity. Below are ten reasons why Catholics cannot be Masons or participate in their activities.
1). The Holy See on Nov. 26, 1983, at the direction of the Pope, issued a "Declaration on Masonic Associations" restating the Church's position condemning the basic principles of Freemasonry. It also states that Catholics who join Masonic organizations are in a state of grave sin and are automatically denied Holy Communion.
2). God as described in Masonic works is an impersonal "Great Architect of the Universeî," not the personal God of the Patriarchs, the One True God of Revelation, the Father, the Son and Holy Spirit.
3). Masonic writings specifically deny that God has revealed Himself and His truths to us, or that He ever established a Church.
4). In Masonry Jesus Christ is portrayed as merely a man, a great teacher, on a par with Buddha or Mohammed and His Divinity is denied.
5). The Trinity is denied and compared to the "trinitiesî"of pagan religions. The Holy Spirit is blasphemed by Masonry's denial of the Divine Inspiration of Scripture.
6). Christianity is considered a derivative of ancient pagan religions and like all religions deliberately ladens itself with error. God is portrayed as a deceiver who leads many men away from truth as not all are worthy of it.
7). All truth is relative according to Masonry, thereby rejecting objective, absolute truth and therefore the dogmas of the Catholic faith.
8). Freemasonry is portrayed as the foundation of all religion and it is built on Naturalism, a system of belief that makes human nature and human reason supreme in all things.
9). At the various degrees when an oath is sworn, even the initial ones, it is a blood oath swearing for example, "binding myself by no less penalty than that of having my throat cut from ear to ear, my tongue torn out by its roots, and buried in the sands of the sea..." This is a real oath sworn with one's hand on the Bible or Torah, etc.
10). One can easily be deceived by Masonry's rituals and symbols that an objective transformation of man is being carried out. This will lead one away from the workings of God's grace especially manifested in the Sacraments instituted by Christ. Remember, Masonry denies Christís Divinity and therefore His role as our Savior.
For further information the book "Freemasonry: Mankind's Hidden Enemy"can be obtained from TAN BOOKS, Rockford,IL., ($8.00 retail). Your local bookstore can order it for you.
I do not know if the book is available here in Manila in Totus Bookstore.

Don't count on it.
