The Mother of God is so much closer to God than others who draw near to Him, that she is able to intercede more powerfully than any of them; and by this I mean not just human beings, but even all the ranks of angels. Isaiah [the Prophet] writes of the highest order of angels in heaven: 'And the Seraphim stood round about Him' (Isa. 6:2); whereas David says of the Mother of God: 'At Thy right hand stood the queen ...' (Ps. 44:8). ... the Seraphim are 'round about' God, but only the Queen of all stands beside Him.
