text: can i be ex-communicated from the catholic church for becoming a free-mason? ive read on some websites that catholics can be excommunicated for being masons because of the conflict of beliefs. you can be excommunictated from the church for being a mason, but that almost never happens.  i am a catholic and a mason.  it is true that catholicism would prefer its members to join the knights of columbus, and frown on the joining of freemasonry.  the truth is that the catholic knights of columbus are very strongly based on freemasonry!  still, while catholicism has papal denouncements of freemasonry, masons do not care what religious affiliation our members have.  being a catholic, i struggle with this, but i also know that if freemasonry ever acted contrary to my beliefs, i would not be inolved with it, and here i am, still a member and i love the fraternity.  please don't let brother dan y's grammar, punctuation, and  spelling of the word "clue" above lead you to believe that we are not intelligent people.  we come from all walks of life.  some brothers are rural farmers, some are waiters, some are bankers, and some are computer programmers.  not all of us have mastered the art of communication and spelling :)
