Non serviam
Non serviam is Latin for "I will not serve". The phrase is generally attributed to Lucifer, who is said to have spoken these words to express rejection to serve God in the heavenly kingdom.
Today "non serviam" is also used or referred to as motto by a number of political, cultural, and religious groups to express their wish to rebel; it may be used to express a radical view against established common beliefs and organisational structures accepted as the status quo.
