Petrović was born in the nearby village of Gradac, just outside of the town of Raška, in 1871. His mother died when he was a youngster and his father, a military man, was killed in the Serbo-Bulgarian War of 1885. As a 14-year-old he went to Belgrade to live with his uncle Stanojlo Petrović and aunt Draginja, who carefully tended to his education. Mihailo graduated from the Faculty of Theology at the Grandes écoles in 1895. That same year he married Leposava Obradinović, the daughter of a wealthy Belgrade industrialist, and then joined the priesthood in the ranks of married man. He settled first at Ivanjica, where he had distant relatives. There he officiated the funerals of Mihailo Mihailović in 1905 and Smiljana Mihailović five years later, the parents of Dragoljub Mihailović. Later, he was transferred to a parish in Raška where he remained a priest until retirement. In 1904 when King Peter I was crowned, Very Reverend Mihailo Petrović was an invited guest of the new king at the grand reception in Belgrade. During the Serbian uprising of 1904 in Old Serbia, the Balkan Wars, and the Great War, he served as a military pastor to the fighting men at the front lines. He started writing for the Glasnik of the Serbian Orthodox Church as a regular contributor soon after becoming a priest. Among his colleagues at the time were Milan Rakić, Jovan Dučić and other prominent Serbian men of letters, theologians, and politicians.
Serbian Chetnik Organization
He joined early the Serbian Chetnik Organization, formed to rid the Turk from the Balkans and consequently mainland Europe. Petrović was also a member of the Association of Reserve Officers and Warriors that commissioned a number of monuments to the fallen Chetnik fighters in the mid-1920s. It was an opportunity to praise the Chetnik leaders' effort for the liberation of Old Serbia and to criticize the post-war neglect of Serbian war veterans, to attack those who too easily forgot the great sufferings the Serbian people in their plight for emancipation. The first reliable data about early Chetnik activity came with the fall of Communism in the 1990s, written by Vladan Virijević, a professor from Kosovo-Metohija, who mentions archpriest Mihailo Petrović "as an old warrior" who came to bless Chetnik standards, banners and flags in villages and towns throughout Raška in 1937 at a time of the Concordat crisis in Yugoslavia. Petrović was a representative of the Bishop of Zicha, Dr. Nikolaj Velimirović and an archpriest and administrator of the Diocese of Studenica with its seat in Raška. As a contributing editor to the Glasnik of the Patriarchate of Belgrade, Petrović often emphasized in his articles the continued security threats Serbs faced in the region, writing about the need to organize armed or paramilitary defenses against those national threats. Petrović was calling for a continued role for the Chetniks in the southern regions of Serbia through the 1930s, if not before.
Family
During World War II his four sons, Ljubiša, Dragiša, Milan and Aleksandar remained loyal to the Old Order. Father Mihailo's married daughter Vidosava and her husband Very Reverend Svetozar Milenković, with the help of her younger brother Aleksandar, saved a Jewish family from the Nazis in the early years of the war. They are Righteous Among the Nations, and are known collectively as the Milenković family.
