On December 16, 2010, Bishop Coakley was appointed by Pope Benedict XVI as the fourth Archbishop of the Archdiocese of Oklahoma City. He was installed as Metropolitan Archbishop on February 11, 2011.
Archbishop Coakley has selected "Duc in Altum" as his episcopal motto (Put out into the Deep). It is found in St. Luke’s gospel when Jesus, after teaching the crowds from Simon’s boat, invites the apostles to “put out into the deep” and lower their nets for a catch (Lk.5:4). Obedient to Jesus’ command, Simon Peter and his companions cast their nets as directed, and “caught such a great number of fish that their nets were at the breaking point” (Lk. 5:4). Jesus calls the Church today, as always, to put out into the deep, as a witness to hope, to hear, and to respond joyfully to his word with faith and confidence. It is a call to embrace the challenges and oppoprtunities of the New Evangelization.
