Irenaeus of Sirmium (d. 304 A.D.) was a bishop in an area near Belgrade in present-day Serbia. He was brought before the governor during the reign of Emperor Diocletian because of the persecution of Christians. St. Irenaeus of Sirmium was tortured, imprisoned and then was beheaded for his refusal to sacrifice to pagan gods. His body was thrown into the river. He is commemorated today in the Catholic Church, while the Orthodox Churches on the Old Calendar commemorate him on April 6 [2][3][4].

Author's note: There is a difference between Eastern Catholic Churches and Eastern Orthodox Churches. Eastern Catholics are in communion with the Vatican but retain their liturgical, theological, and cultural traditions. Eastern Orthodox Churches are independent from the Vatican and maintain their own leadership and traditions. Usually, Saints that are commemorated in the area of Eastern Europe and the Asia Minor area have different dates of commemoration due to this generally known difference [5].
