Most lodges are only interested in any wrong doings as a legal adult (21 years of age or older) unless they have a younger age for membership (some states allow membership at 18 or 19). Moral turpitude may be spelled out in the jurisdiction’s Grand Lodge Constitution. For example, this is how ours defines Moral Turpitude:
“25.1. Any conduct of a Mason involving “moral turpitude” whether committed before or after initiation, is a Masonic offense.
25.2. MORAL TURPITUDE—The term “Moral Turpitude” means more than “Immorality”; there must be involved in the offense charged not only immorality but also an element of inherent baseness, vileness or depravity.
25.3. Any conduct unbecoming a gentleman and which tends to bring discredit upon the brother and embarrassment or disrepute upon the Fraternity is a Masonic offense.”
And then so-called immorality is usually based on the community moral standards in which you live.
Also, in our jurisdiction, you do not have to disclose ALL history. We only ask about any history involving a felony charge. And even if you do have a felony it does not automatically disqualify you from membership. We would take into account when it occurred and whether or not you have taken strides to turn your life around afterwards.
