In literature, the Latin phrase non serviam was spoken by Satan as he refused to serve God. It translates into "I will not serve."

The origin of this attribution to Satan is unknown. It does not appear in the Bible. It might have originated in one of Friedrich Nietzsche's works, quoting an older source, but this is unconfirmed.

The phrase is used by several political, cultural, and religious groups who do not want to conform.
