“Christian tradition above all thinks of Michael as the one who is successful in combating Satan.”

A statue of St. Michael is a prominent landmark in the capital city of Kyiv (shown above) and a monastery nearby bears the saint’s name.

There’s a reason for that, according to this Ukrainian website: 

Over all the Nine Ranks of Angels, the Lord put the Holy Leader [Archistrategos] Michael (his name in translation from the Hebrew means “Who is like unto God”) — a faithful servitor of God who hurled down from Heaven the arrogantly proud Lucifer together with the other fallen spirits.

… Christian tradition above all thinks of Michael as the one who is successful in combating Satan. Jude (Jude 1:9) mentions the fight over Moses’ body between Michael and the demon. In Revelation (Rev 12:7), Michael and his angles fight the dragon in heaven.

The veneration of Michael began perhaps in Phrygia and was particularly developed in Constantinople and Rus’. In Constantinople, Michael was specially honored as the celestial doctor, who brought healing to the sick. The celebration of the Sobor of the leader of the Heavenly Hosts Michael was established at the beginning of the 4th century.

Our ancestors chose Archangel Michael not only as the patron saint of Rus’, but also of its capital, Kyiv. Many churches have been built in his honor, including the gold-roofed St. Michael’s Sobor in Kyiv.

The image of the Archangel Michael was used on the national coat-of-arms by the Rus’ princes of the Monomakh line. In 1569, when the territories of Kyiv came under control of Poland, Archangel Michael was retained on the crest of the Kyiv Voievodship(?). Archangel Michael was also honored as a heavenly guardian in battles against the enemies of Christianity – the Mongols and Tartars.

The use of Archangel Michael’s image was also prevalent during the kozak era – we find it on many banners from the 16th-18th centuries. [something re Khmelnytsky] It is no surprise the appearance of Archangel Michael on military standards continued into the 20th century – appearing on the flag of the Ukrainian Sich Riflemen (YCC) in 1914. This continued with his use during the revolutionary years of 1917 1923 by the Army of the Ukrainian National Republic as well as the Ukrainian Galician Army (UHA), as well during World War II by the Ukrainian Insurgent Army (UPA).

Archangel Michael also appeared on postage stamps issued by the Western Ukrainian National Republic in the city of Lviv in 1918.
