All the angels are amazed at humans, who through their holy works appear clothed with an incredibly beautiful garment. For the angel without the work of the flesh is simply praise; but the humans with their corporeal works are a glorification! Therefore the angels praise humans' work.
... When one enters the mystery of God, the first mystery is silence. When one loves another, silence is absolutely necessary. Long before lovers can speak openly of their love, they speak by silence, a deep silence, especially when it deals with God. It is by entering the mystery of silence that slowly everyone becomes like our Beloved.
