It means no closed doors! All our rituals, our meetings, any event can be attended by anyone. We are one of the few fraternities in the country where we welcome anyone to attend our rituals. We are a fraternity that has progressed from secrets since 1834 and welcome everyone to know our ideas. In fact, our ritual books and cornerstones are shared during recruitment to show our commitment to non-secrecy!
It has been discovered that as early as 1840 there existed a simple pledge that was recited by new members upon entering the Social Fraternity. Thus, the history of the initiation ritual begins. From that point in 1840, things began to evolve.
