AC 5329 - the presence of angels

AC 5329
... there is a correspondence of all things in the world
with those in heaven;
the angels perceive heavenly things
when a person perceives worldly ones.
Unless this were the case
no angel from heaven could possibly be with a person.
But in order that angels may be with a person,
the Word has been given,
in which the angels may perceive a Divine holiness
which they can communicate
to the person with whom they are present.
