Fun Facts From Church History: Luther’s Name

Most folk think that ‘Luther’ is a form of the family name ‘Luder’ and that Martin Luther simply took to spelling his name in the more modern format.

Not so.  Rather, sometime after the 95 Theses made him well known he adopted the Greek name Ελευθπριυς and though he signed his work with that name for a bit he finally shortened it to the simple ‘Luther’ because he was the ‘freed one’.  See further the discussion in L. Roper ‘Martin Luther’ and the notes thereto (p. 86).
