Rev. Frederick H. Edlefsen, Pastor
Email the Pastor

Please contact Fr. Edlefsen's administrative assistant to arrange a meeting.

Fr. Edlefsen is a native of New Jersey, grew up in Louisiana, went to LSU and then UVA for graduate school. He was ordained in 2001 after his seminary studies at Mount St. Mary's in Emmittsburg, MD. Fr. Edlefsen was Parochial Vicar at St. James in Falls Church from 2001-2005, Chaplain at Bishop O'Connell High School from 2005-2007, Chaplain at the Catholic Campus Ministry at the University of Mary Washington from 2007-2014, and he came to St. Agnes in 2014 as Parochial Administrator. On the Feast of St. Agnes, January 21, 2016, he was made Pastor by Bishop Paul Loverde, who formally installed him in March 2016.

Fr. Edlefsen loves the great outdoors and hiking, enjoys reading history, novels and stories, comedy, social commentaries and theology. His favorite magazine is Montana Outdoors, though he's never lived in Montana (it's a nice thought). He also loves music, everything from classical to folk. On his day off, you might find him at a secluded place along Potomac River or the Shenandoah Mountains reading a good book. Sts. Bernard of Clairvaux and Therese of Lisieux are among his favorite saints.

His hope for St. Agnes is that we grow in holiness as "missionary disciples" of Jesus Christ. He envisions a parish that welcomes people into the fold of Christ's flock so as to become holy in this life and saints for the next. He would like every living room the parish to be a sanctuary of God's peace and charity.
