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.
It is significant that the Latin word "templum" originally meant a vast space, open on all sides, from which one could survey the whole surrounding landscape as far as the horizon. This is what is meant to CONTEMPLATE: to "set one's sights on" Heaven from the temple that defines the field of vision... The temple is the place, the organ of vision.
