That by the angels of God ascending and descending, is to be
understood, that a perpetual intercourse should now be opened
between heaven and earth, through the medium of Christ,
who was God manifested in the flesh.
Our blessed Lord is represented in his mediatorial capacity as
the ambassador of God to men; and the angels ascending and
descending upon the Son of Man, is a metaphor taken from the
custom of dispatching couriers or messengers from the prince
to his ambassador in a foreign court, and from the ambassador
back to the prince.
