There are five basic requirements for Membership in a Masonic Lodge. They are as follows:
1. Being a man, freeborn, of good repute and well-recommended;
Being a man - as Freemasonry is a Fraternity or all male organization, this is a must as the lodge does not admit women. There are however Masonic organizations such as the Order of the Eastern Star, which do.
In the early days of Freemasonry, many citizens were involved in indentured service and thus could not make decisions for themselves. While this is not the case in modern society, the phrase is kept as a reminder of Masonry's rich history.
A prospective member must be of good repute and sponsored by someone who knows his reputation in the community. It is important that a member not be admitted who would stain the reputation and principles of the craft.
2. A belief in a Supreme Being;
No man can be made a Mason if he is an atheist. All masons must profess a belief in a Supreme Being. This is an area where Freemasonry often comes under attack by religious opponents. Because Freemasonry accepts Christian, Moslem and Jew alike how that member chooses to worship God or by which name that member knows God is of no consequence to Freemasonry.
3. Ability to support one's self and family;
While not clearly stated in all jurisdictions, this condition is placed so that a prospective member does not join the craft in the hopes of deriving financial benefit from the order. It also is in place to show the prospective Mason that the Lodge comes after his religious and family responsibilities.
4. Of lawful age;
The prospective Mason must have reached the age of 21 although some jurisdictions allow a member to join at an earlier age.
5. Come to Freemasonry of their "own free will and accord".
Freemasonry, unlike many fraternal organizations, does not seek out members. Rather it requires that members seek out the order. You will not see posters promoting the craft.
