Chris,
I must say that I misspoke.... the Masons might not be anti-Catholic, but the organization is incompatible with the Christian faith.
Freemasonry has a very formal religious system which includes a belief in God as the Grand Architect of the Universe, the immortality of the soul and the resurrection of the body. Masonry also believes that man can achieve salvation by his good works, independent of God's gift of grace. Notwithstanding its belief in God, resurrection of the body, and salvation by works, Masonry does not require its members to believe in Jesus Christ or His Church.
Freemasonry also reverences all religious writings and places these writings on par with Gods written Word found in the Bible. Thus, Masonry places all religious writings on its altar (Book of Mormon, the Vedas, Zend Avesta, the Sohar, the Kabalah, the Bhagavad-Gita, the Upanishads or any other religious writing). This is because, unlike Christianity, Freemasonry does not believe that the Bible is the revealed written Word of God. Instead, Freemasonry views all religions as equally plausible attempts to explain the truth about God which, in the end, cannot be known.
My Grandfather (may God have mercy on his soul) was a 32nd level Mason.... so I know a bit about what the group really stands for.
I hope you do too.
