### Priesthood

Mussio was ordained to the priesthood for the Archdiocese of Cincinnati by Archbishop John T. McNicholas on August 15, 1935. Mussio then traveled to Rome to study at the Pontifical University of Saint Thomas Aquinas. He earned a doctorate in canon law in 1939 with a dissertation entitled "The Education of Offspring : a Primary End of Matrimony"
Following his return to Cincinnati in 1939, Mussio was appointed as assistant chancellor of the archdiocese. He was named chancellor and a papal chamberlain in 1942. In addition to his other duties, Mussio taught canon law at Mount St. Mary's Seminary.

### Bishop of Steubenville

On March 10, 1945, Mussio was appointed the first bishop of the newly erected Diocese of Steubenville by Pope Pius XII. He received his episcopal consecration on May 1, 1945, from Archbishop McNicholas, with Bishops Michael Ready and George Rehring serving as co-consecrators, at St. Monica's Pro-Cathedral. He was installed at Holy Name Cathedral in Steubenville on May 23, 1945. In 1958, Mussio joined with the other Catholic bishops of Ohio in opposing a so-called right to work amendment to the Ohio Constitution that would have outlawed mandatory union membership in unionized workplaces.
As bishop, Mussio established 73 parishes and 20 missions, the College of Steubenville in Steubenville, St. John Vianney Seminary, a Camaldolese hermitage, Samaritan House, Catholic Social Services, and St. John's Villa. He also founded the diocesan newspaper, The Steubenville Register. Mussio was appointed an assistant at the pontifical throne on June 8, 1960. In a 1960 article in the publication Ave Maria from the University of Notre Dame, Mussio said that existing parish structures were outdated and cumbersome. He believed that lay people needed to relieve priests of administrative roles in their parishes so that the priests could spend more time evangelizing and ministering to parishioners.
Between 1962 and 1965, Mussio attended all four sessions of the Second Vatican Council in Rome. In accord with the Council's reforms, he established the Steubenville Ecumenical Institute to foster better relationships among Christians and Jews.
