Many men live a lifetime and never know they must ask for admission to the world's oldest, most purposeful, and greatest fraternity. They do not realize that they will not be invited. They must come of their own free will and accord, without persuasion. They must ask a Mason for a petition.
The first step is to contact the lodge.
For membership in Tennessee, you must:
be a man;
be at least 18 year of age;
have a belief in a Supreme Being and the immortality of the soul;
be capable of reading and writing;
have good moral character;
be recommended by two Master Mason members of the lodge;
have two additional references (who may or may not be Masons);
be able to pass a multi-state background check.
