According to the Preamble to the Constitution of the Grand Lodge of the District of Columbia

Freemasonry is a charitable, benevolent, educational and religious society.
Its principles are proclaimed as widely as men will hear. Its secrets are in its methods of recognition and of symbolic instruction.
It is charitable in that it is not organized for profit or for the financial benefit of any individual and it is devoted to the promotion of the welfare and happiness of mankind.
It is benevolent in that it teaches and exemplifies altruism as a duty. It is educational in that it teaches by prescribed ceremonials a system of morality and brotherhood based upon Sacred Law.
It is religious in that it teaches monotheism, the Volume of Sacred Law is open upon its altars whenever a Lodge is in session, reverence for God is ever present in its ceremonial, and to its brethren are constantly addressed lessons of morality; yet it is not sectarian or theological.
It is a social organization only so far as it furnishes additional inducement that men may forgather in numbers, thereby providing greater opportunity for its primary work of education, worship and charity.
Through the improvement and strengthening of the character of the individual man. Freemasonry seeks to improve the community. Thus it impresses upon its members the principles of personal righteousness and personal responsibility, enlightens them as to those things which make for human welfare, and inspires them with that feeling of charity, or good will, toward all mankind which will move to translate principle and conviction into action.
To that end, it teaches and stands for the worship of God; truth and justice; fraternity and philanthropy; and enlightenment and orderly liberty, civil, religious and intellectual. It charges each of its members to be true and loyal to the government of the country to which he owes allegiance and to be obedient to the law of any state in which he may be.
It believes that the attainment of these objectives is best accomplished by laying a broad basis of principle upon which men of every race, country, sect and opinion may agree rather than by setting up a restricted platform upon which only those of certain races, creeds and opinions can assemble.

Vision: To unite men of different beliefs and cultures into one common society of friends and brothers.
Mission: To unite men of different beliefs into a harmonious and productive community through the application of Masonic moral values and the practice of benevolence, intellectual development, and mutual respect.
