and that's for sure!

The Catholic Church, as far as I know, is still very anti Freemasonry:

"On 19 July 1974 this Congregation wrote to some Episcopal Conferences a private letter concerning the interpretation of can 2335 of the Code of Canon Law which forbids Catholics, under the penalty of excommunication, to enroll in Masonic or other similar associations...

...Historically, one of Masonry's primary objectives has been the destruction of the Catholic Church; this is especially true of Freemasonry as it has existed in certain European countries. In the United States, Freemasonry is often little more than a social club, but it still espouses a naturalistic religion that contradicts orthodox Christianity"

There may be some changes, but I always understood excommication came with enrolling in a Masonic association.

Actually, that site also says:

"Because the revised code of canon law is not explicit on this point, some drew the mistaken conclusion that the Church's prohibition of Freemasonry had been dropped. As a result of this confusion, shortly before the 1983 code was promulgated, the Sacred Congregation for the Doctrine of the Faith issued a statement indicating that the penalty was still in force. This statement was dated November 26, 1983 and may be found in 13/27 (Nov. 15, 1983), 450."
