But Master John, elected to the bishoprick of Elphin by Clarus, Archdeacon of that see, and by Malachy the Cathedral Dean and Gelasius the Sacristan, proceeded to visit the Lord Pope at Lyons-sur-Rhone, where he was in exile, having been expelled from the Holy See by the Roman Emperor; and he found such favour in the eyes of the Lord Pope and of the papal court that the election of Comarba Comain by the junior canons of the choir of Elphin was quashed, while his own election by the elder clergy, though fewer in number, was honoured, the Lord Pope giving him letters for the Archbishop of Tuaim ordering his consecration as bishop in the name of Jesus Christ our Lord. He was consecrated, and on the day of his consecration the faithful of Christ and seekers to preserve the truth answered: Thanks be to God.
