As an LCMS member, you've likely heard a lot of the negatives about Masons.
As a Lutheran and a Mason, I can tell you that the majority of it is distorted and blown out of proportion.
The Masons is a club, just like the Elks, the Boys Scouts and the local book club. It uses some quasi-religious symbols, but I have NEVER been asked to do, say or agree to anything in the Masons that violates my Lutheran beliefs.
A few of the criticisms leveled at the Lodge, along with my responses:
The Lodge is a substitute for membership in a congregation.
That is absolutely true. Many people make Lodge membership a priority over attending worship. People do the same with sports, sleep (hard to get up on Sunday morning), drinking, TV, etc., etc. Avoiding this is a matter of balance.
The Lodge presents a generic or pagan image of God.
The Lodge acknowledges the importance of the Creator, but does not say that the Creator is Jehovah, Allah, Buddah or Zarquon the Space God.
Similar approaches are taken by the Boy Scouts, Alcoholics Anonymous, and even our government -- our money says "In God We Trust," but that means different things to different people.
The Lodge does not promote Christianity.
That is correct. It does require a person to believe in God, but does not require that person to adhere to a particular religion or fellowship. The Boy Scouts does the same thing -- Scouts are required to acknowledge God, and that organization promotes awards for Scouts who meet certain requirements within their worship community. Those awards are given for service to Christian fellowships, Mormon, Islamic and a vareity of other religions.
The Masonic Lodge is a religion.
It does use some forms of religion, but all of our venerated social institutions use some ceremonial forms -- courts, governmental bodies, clubs, families, etc.
