March 18th is the Anniversary of his death and so I post below information on this saint from Orthodoxwiki.
Nikolaj Velimirović was born in the small village of Lelich in Western Serbia. He attended the Seminary of St. Sava in Belgrade and graduated in 1905. He obtained doctorates from the University of Berne (1908), while the thesis was published in German in 1910, whereas the doctor’s degree in philosophy was prepared at Oxford and defended in Geneva (Filosofija Berklija – Berkeley’s Philosophy, in French) in 1909. At the end of 1909 he entered a monastic order. In 1919, then Archimandrite Nikolai was consecrated Bishop of Žiča in the Church of Serbia.
In April 1915 (during WWI) he was delegated to England and America by the Serbian Church, where he held numerous lectures, fighting for the unison of the Serbs and South Slavic peoples. At the beginning of 1919 he returned to Serbia, and in 1920 was posted to the Ohrid archbishopric in Macedonia, where in 1935, in Bitola he reconstructed the cemetery of the killed German soldiers.
During the Second World War in 1941 Bp. Nikolai was arrested by the Nazis in the Monastery of Žiča (which was soon afterwards robbed and ruined), after which he was confined in the Monastery of Ljubostinja (where, on the occasion of mass deaths by firing squad, he reacted saying: “Is this the German culture, to shoot hundred innocent Serbs, for one dead German soldier! The Turks have always proved to be more just…”). Later, this “new Chrysostom” was transferred to the Monastery of Vojlovica (near Pančevo) in which he was confined together with the Serbian patriarch, Gavrilo (Dožić) until the end of 1944.
On December 14, 1944 he was sent to Dachau, together with Serbian Patriarch Gavrilo, where some sources, especially the standard Church references, record that he suffered both imprisonment and torture.
After the War he left Communist Yugoslavia and immigrated as a refugee to the United States in 1946 where he taught at several Orthodox Christian seminaries such as St. Sava’s Serbian Orthodox Seminary in Libertyville, Illinois and St. Tikhon’s Orthodox Theological Seminary and Monastery in South Canaan, Pennsylvania (where he was rector and also where he died) and St. Vladimir’s Orthodox Theological Seminary now in Crestwood, New York. He died on March 18, 1956.
On May 19, 2003, the Holy Assembly of Bishops of the Serbian Orthodox Church, with one heart and one voice, unanimously decided to enter Bishop Nicholai (Velimirovic) of Ohrid and Ziča into the calendar of saints of our Holy Orthodox Church.
St. Nikolai Velimirovich is often referred to as Serbia’s New Chrysostom. St. John Maximovitch, who had been a young instructor at a seminary in Bishop Nikolai’s diocese of Ohrid, called him “a great saint and Chrysostom of our day [whose] significance for Orthodoxy in our time can be compared only with that of Metropolitan Anthony (Khrapovitsky). … They were both universal teachers of the Orthodox Church.”
Troparion (Tone 8)
O golden-tongued preacher proclaiming the risen Christ,
Everlasting guide of the cross-bearing Serbian people,
Resounding harp of the Holy Spirit, and dear to monastics who rejoice in you,
Pride and boast of the priesthood, teacher of repentance, master for all nations,
Guide of those in the army of Christ as they pray to God,
Holy Nicholas teacher in America and pride of the Serbian people,
With all the saints, implore the only Lover of mankind
To grant us peace and joy in his heavenly kingdom!
