A Greek Catholic priest in the Diocese of Munkács, and later a Hungarian Greek Catholic pastor serving in the United States.
His father was György Suba, a Greek Catholic priest, and his mother was Paulina Gebé. Among his siblings were two other priests: Arnold András Suba, who also served in the United States, and Viktor Suba, who remained in Hungary. Among his sisters, a later American source mentions Helen Demjanovis, Eugenia Holosnay, and Andrea Hrenyo; another sister was the wife of Greek Catholic priest Nicholas Chopey.
He completed his theological studies in Uzhhorod and Budapest; he also studied theology at the University of Budapest. Gyula Firczák, Bishop of Munkács, ordained him a priest in Uzhhorod in 1905. Sources provide differing dates for the ordination: a Hungarian ecclesiastical source gives April 16, 1905, while his American obituary lists June 6, 1905.
He began his priestly ministry at the bishop’s office in Munkács. From 1901 to 1904, he served as the bishop’s archivist and registrar; from 1904 to 1908, as a clerk; and from 1908 to 1911, as a secretary and chief secretary of the diocesan curia. In addition, he taught at the teacher training college in Uzhhorod. Later, he served as a field chaplain in the army of the Austro-Hungarian Monarchy; according to his American obituary, he held the rank of captain. Hungarian sources place his service as a field chaplain between 1911 and 1913.
According to his American obituary, he arrived in the United States in 1912, while other sources indicate that he began his work in the U.S. in 1913. During the first phase of his pastoral career in the United States, he served in Hungarian and Ruthenian Greek Catholic communities in Pennsylvania, Ohio, and New Jersey. His American obituary lists Scranton, Youngstown, Toledo, Trenton, and Homestead among his places of service. According to a church history source from New Castle, he was also the pastor of the local St. Nicholas Greek Catholic Church for a brief period around 1919–1920.
In Youngstown, he served as pastor of the Hungarian St. George Greek Catholic parish. Contemporary Hungarian-American press sources from 1922 also confirm his ministry there under the name “Ernő Suba.” Based on earlier church directories, his ministry in Youngstown can be dated to 1921–1927. Subsequently, from 1927 to 1931, he served in Toledo. The records of the mother diocese listed him as a priest on leave of absence starting in 1931; however, this did not mean that his pastoral work in the United States had ceased.
He later served in Homestead, Pennsylvania, where he retired. He then moved to Wilkes-Barre and served as an assistant pastor at St. Mary’s Greek Catholic Church alongside his brother-in-law, Nicholas Chopey. A Hungarian source documents his service there in 1937–1938; in 1942, a Hungarian list of priests still mentions him in connection with Wilkes-Barre.
In the final years of his life, he suffered from prolonged illness. He passed away on July 15, 1950, at the age of 72, in Danville, Pennsylvania. His gravestone still stands today, bearing the inscription “Rev. Ernest Suba, 1877–1950.”

Sources provide differing dates for his ordination: April 16, 1905; June 6, 1905.
