O God, who in the glorious Transfiguration of your Only Begotten Son confirmed the mysteries of faith by the witness of the Fathers and wonderfully prefigured our full adoption to sonship, grant, we pray, to your servants, that, listening to the voice of your beloved Son, we may merit to become coheirs with him. Who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever. Amen
