McNamara then attended St. Mary's Seminary in Baltimore, Maryland and the Catholic University of America in Washington, D.C.[2]
McNamara was ordained to the priesthood for the Archdiocese of Chicago by Cardinal George Mundelein on December 23, 1922.[3] McNamara became a professor at Archbishop Quigley Preparatory Seminary in Chicago in 1925, and served as a chaplain at St. Vincent Infant Hospital in Chicago from 1932 to 1937. McNamara was made pastor of St. Francis Xavier Parish in Wilmette, Illinois, in 1937, and named a domestic prelate by the Vatican in 1946.
On December 17, 1948, McNamara was appointed as the first bishop of the newly erected Diocese of Joliet in Illinois by Pope Pius XII. He received his episcopal consecration on March 7, 1949, from Cardinal Samuel Stritch, with Bishops John Boylan and Albert Zuroweste serving as co-consecrators. McNamara also served as chancellor of the College of St. Francis in Joliet.[4]
