Quis ut Deus? (or Quis sicut Deus?), a Latin sentence meaning "Who [is] like God?", is a literal translation of the name Michael (Hebrew: מִיכָאֵל, transliterated Micha'el or Mîkhā'ēl).
The sentence Quis ut Deus? is particularly associated with Archangel Michael.[1][2] In art, St. Michael is often represented as an angelic warrior, fully armed with helmet, sword, and shield, as he overcomes Satan, sometimes represented as a dragon and sometimes as a man-like figure. The shield at times bears the inscription: Quis ut Deus,[3] the translation of the archangel's name, but capable also of being seen as his rhetorical and scornful question to Satan.[4]
The Scapular of St. Michael the Archangel also bears this phrase.[5]
