I believe that Phi Kappa Psi is a brotherhood of honorable men, courteous and cultured, who pledge throughout their lives to be generous, compassionate, and loyal comrades;
I believe that I am honor bound to strive manfully for intellectual, moral, and spiritual excellence; to help and forgive my Brothers; to discharge promptly all just debts; to give aid and sympathy to all who are less fortunate;
I believe that I am honor bound to strengthen my character and deepen my integrity; to counsel and guide my Brothers who stray from their obligations; to respect and emulate my Brothers who practice moderation in their manners and morals; to be ever mindful that loyalty to my Fraternity should not weaken loyalty to my college, but rather increase devotion to it, to my country, and to my God;
I believe that to all I meet, wherever I go, I represent not only Phi Kappa Psi, but indeed the spirit of all fraternities; thus I must ever conduct myself so as to bring respect and honor not to myself alone, but also to my Fraternity;
To the fulfillment of these beliefs, of these ideals, in the noble perfection of Phi Kappa Psi, I pledge my life and my sacred honor.
