[1] Matejić was born in Smederevo in what was then the Kingdom of Serbs, Croats and Slovenes (today Serbia) and educated there.
As a seminarian at Bitola during the Axis occupation of Yugoslavia, he left the country and completed his seminary education in a displaced persons camp in Eboli, Italy.
In 1949, at another camp in West Germany, he married Ljubica Nebrigić of Srem (who preceded him in death on 17 April 2016).
As a priest, he founded two parishes and encouraged and physically contributed to the building of two places of worship, the Church of St. George in Monroe, Michigan (where he served from 1956 to 1967), and the Church of St. Stevan of Dečani in Columbus, Ohio (where he served from 1967 until his retirement in 1990).
In September 2000 he received two awards from the Serbian Orthodox Church, the St. Sava Medal (the highest), presented to him in Ohio, and the next day a gramata from Patriarch Pavle in Belgrade.
