He was ordained May 25, 1996, at the Cathedral of the Most Blessed Sacrament in Detroit by then-archbishop Cardinal Adam Maida. Archbishop-designate Byrnes considers his great-uncle, Fr. Remy McCoy, an order priest of the Missionaries of Africa who served in Ghana, as a major influence on his path to the priesthood. Fr. McCoy passed away in 1990. Archbishop-designate Byrnes began his priestly ministry as associate pastor at St. Joan of Arc parish in St. Clair Shores and as an adjunct faculty member at Sacred Heart Major Seminary. He served in those roles until 1999, at which time he departed to Rome to study at the Pontifical Gregorian University. He earned his Doctorate in Sacred Theology in 2003. Returning to Detroit, he joined the faculty of Sacred Heart Major Seminary and served as weekend assistant at three Detroit parishes: Presentation/Our Lady of Victory, St. Gregory the Great, and Church of the Madonna.
In January 2004 he was named Vice Rector of Sacred Heart Major Seminary and also pastor of Presentation/Our Lady of Victory, where Deacon Hubert Sanders is the deacon administrator. Additionally, between 2007 and 2009, he served on the archdiocesan Presbyteral Council. After being ordained a bishop on May 5, 2011, Archbishop-designate Byrnes assisted Archbishop Vigneron in pastoral oversight of the northeast region of the Archdiocese of Detroit, which includes parts of Macomb, St. Clair, and Lapeer counties. In October 2012, Archbishop-designate Byrnes was asked by Archbishop Vigneron to lead key efforts in the Archdiocese of Detroit related to evangelization. These efforts include the Unleash the Gospel New Evangelization initiative and the upcoming Archdiocesan synod.
