Mission Statement

The Phi Delta Theta Mission Statement: Phi Delta Theta was organized with three principle objectives: The cultivation of friendship among its members; the acquirement individually of a degree of mental culture, and the attainment personally of a high standard of morality. The Three Cardinal Principles of Phi Delta Theta:

Friendship: When forming Phi Delta Theta, the founders saw inspiration in the friendship enjoyed by the ancient Greeks. They characterized friendship as a unity of skills, tastes and thoughts; not as a loss of personal identity, but rather a search for truth and a desire to be united with others who sought the same. To put it simply, friendship is being there for each other through life’s trials and to offer sound advice.

Sound Learning: Sound learning means more than getting good grades; it’s about having intellectual curiosity. The founders saw learning as a search for the truth; truth that is found through intellectual quests. A good student isn’t necessarily the one who receives straight A’s; a good student is one who is excited about learning and is driven by knowledge. His drive of continual learning continues after graduation and throughout life.

Rectitude: The six original founders were men of strong Christian faith. Several went on to pursue occupations as ordained ministers. It’s unfortunate that the word ‘rectitude’ brings to mind simply going to church or abstaining from alcohol. The men of Phi Delta Theta know that rectitude has more to do with the way a man approaches living. It revolves around doing what should be done because it’s the right thing to do. In these three ways, a man can live a life of integrity and the men of Phi Delta Theta have counted on the Cardinal Principles to see them through their lives during college and beyond.
