Angels are intelligent reflections of light, that original light which has no beginning. They can illuminate. They do not need tongues or ears, for they can communicate without speech, in thought.
John of DamascusMore John of Damascus quotes
The saints must be honored as friends of Christ and children and heirs of God. Let us carefully observe the manner of life of all the apostles, martyrs, ascetics, and just men who announced the coming of the Lord. And let us emulate their faith, charity, hope, zeal, life, patience under suffering, and perseverance unto death so that we may also share their crowns of glory.
John of Damascus
