And one cried unto another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.
All Commentaries on Isaiah 6:3 Go To Isaiah 6
John Chrysostom
AD 407
Do you desire to learn how the powers above pronounce that name; with what awe, with what terror, with what wonder? “I saw the Lord,” says the prophet, “sitting upon a throne, high, and lifted up; around him stood the seraphim; and one cried to another and said, “Holy, holy, holy, Lord God of hosts; the whole earth is full of his glory!” Do you perceive with what dread, with what awe, they pronounce that name while glorifying and praising him? But you, in your prayers and supplications, call upon him with much listlessness; when it would become you to be full of awe and to be watchful and sober!
