Michael is an archangel in the Christian tradition, not a saint, and anyway he is often referred to as "Saint Michael" or "Saint Michael the Archangel", though this honourable title does not indicate canonization. Orthodox church gives him also the title "Archistrategos", or "Supreme Commander of the Heavenly Hosts".
The name “Michael” from Hebrew means "who is like God" (mi-who, ke-as or like, El-deity), which is traditionally interpreted as a rhetorical question: "Who is like God?"
In the Middle Ages Michael, together with St George, were considered patron saints of chivalry. His feast day was celebrated as a holy day of obligation. Consequently, Michael became the patron of the warriors, Ukrainian Cossacks, police officers, soldiers and the Catholic Police Guild. St Michael is also the protector of horses, horsemen and hunters and the patron of Germany, Brussels and Kiev.

St Michael’s Day is celebrated on September 29 in the Catholic, Anglican and Lutheran traditions. Orthodox Church celebrates the principal feast of St Michael on November 21, honoring him along with the rest of the "Bodiless Powers of Heaven" as their Supreme Commander; there is also an Orthodox feast on September 19 which commemorates his miraculous appearance at Chonae, details of which are given in the next section “Legends of the Angel”.
